Precautions
If the safety of personnel requires the prohibition of unwanted or unexpected starts, electronic locking is performed by the
Altivar 71's “Power Removal” function.
This function requires the use of connection diagrams conforming to category 3 of standard EN 954-1 and safety integrity level 2
according to IEC/EN 61508.
The Power Removal function takes priority over any run command.
Read and understand the instructions in the "programming manual".
INCOMPATIBLE LINE VOLTAGE
Before switching on and configuring the drive, ensure that the line voltage is compatible with the supply voltage range
shown on the drive nameplate. The drive may be damaged if the line voltage is not compatible.
Failure to follow these instructions can result in equipment damage.
UNINTENDED EQUIPMENT OPERATION
• Before switching on and configuring the Altivar 71, check that the PWR (POWER REMOVAL) input is deactivated (at
state 0) in order to prevent unexpected starts. Do not forget to reactivate the Power Removal input to start the motor.
• Before switching on or on exiting the configuration menus, check that the inputs assigned to the run command are
deactivated (at state 0) since they can cause the motor to start immediately.
Failure to follow these instructions will result in death or serious injury.

Mounting in a wall-mounted or floor-standing enclosure
Installing the heatsink inside the enclosure
The power dissipated by the drive power components is given in the table below.
Power dissipated
These levels of power dissipation are given for operation at nominal load and for a switching
frequency of 2.5 Hz.
The drive has a fan for cooling the power components. The air is circulated from the bottom to
the top of the unit via a duct (the duct is shown shaded gray on the diagram opposite). This duct
is isolated from the control section by IP54 protection. The DC choke extends this duct while
maintaining IP54 protection.
The drive dissipates a great deal of power which must be evacuated to the outside of the
enclosure.
Air inlets and outlets must be provided to ensure that the flow of air in the enclosure is at least
equal to the value given in the table below for each drive.
Several methods of evacuation are possible. The following is a proposed method for IP23 and
IP54 mounting.
IP23 mounting (standard operating conditions):
Figure 1
Install the drive on an enclosure baseplate.
Install the DC choke in accordance with the mounting recommendations.
The simplest mounting is to extend the IP54 duct between the upper outlet of the DC choke
and the top of the enclosure . Fixing points are provided for this purpose on the top of the
DC choke.
The hot air is thus evacuated to the outside and does not contribute towards increasing the
internal temperature of the enclosure.
It is advisable to add a plate approximately 150 mm from the top of the enclosure over the
air outlet opening to prevent foreign bodies falling into the drive cooling duct.
The air inlet can be via a grille on the bottom front panel of the enclosure door, in accordance
with the required flow rates given in the above table.
Figure 2
It is advisable to use a kit for IP31/NEMA type 1 conformity (to be ordered as an option) for
attaching the power cables. The design of the IP31 kit is based on the same principle as the
DC choke, and has an IP54 duct to help guide the incoming air.
Note:
- If the air in the power circuit is totally evacuated to the outside, very little power is dissipated
inside the enclosure. In this case, use the dissipated power table for dust and damp proof
flange mounting (see the next page).
- Connect all the additional metal parts to ground.

Mounting in a wall-mounted or floor-standing enclosure
Mounting the heatsink inside the enclosure (continued)
IP54 mounting (standard operating conditions):
The drive must be mounted in an IP54 enclosure in certain environmental conditions: dust,
corrosive gases, high humidity with risk of condensation and dripping water, splashing liquid,
etc.
The simplest way of obtaining an enclosure with IP54 protection is to follow the mounting
recommendations for IP23 protection with the following 5 additional points:
1 Do not make an air inlet hole in the enclosure door. The air will enter through the bottom of
the enclosure via a plinth added for the purpose.
2 Add the IP31 or NEMA type 1 conformity kit in accordance with the mounting instructions.
3 Add an enclosure baseplate designed to provide IP54 protection around the power cables.
4 Add an air evacuation duct between the baseplate and the duct of the IP31 or NEMA type 1
conformity kit. The IP31 or NEMA type 1 conformity kit enables an extension duct to be
mounted. Drill a hole in the base of the enclosure to allow air to enter. Place seals around the
duct that has been added to maintain IP54 protection.
5 Add a 200 mm plinth at the bottom of the enclosure with grilles to allow air to enter.
Note: Connect all the additional metal parts to ground.
Dust and damp proof flange mounting (heatsink outside
the enclosure)
This mounting is used to reduce the power dissipated in the enclosure by locating the power
section outside the enclosure.
This requires the use of the dust and damp proof flange mounting kit VW3A9509...517
(please refer to the catalog).
The degree of protection for the drive mounted in this way becomes IP54.
To fit the kit to the drive, please refer to the manual supplied with the kit.

Installing the kit for IP31/NEMA type 1 conformity
On ATV71H D55M3X to D75M3X and D90N4 to C50N4 drives, the cable shielding can be attached and connected to ground using one of
the following two kits:
• Kit for IP31 conformity (VW3 A9 109 ... 116)
• Kit for NEMA Type 1 conformity (VW3 A9 209 ... 216)
This kit is not supplied with the drive. It must be ordered separately (please refer to the catalog). It is mounted under the drive as shown
below.
- Mount the chassis on the wall or in the bottom of the enclosure under the drive. Ensure that the chassis is tightly secured to the
drive to maintain the IP54 seal of the ventilation duct.
- Mount the EMC plate on the kit chassis using the screws provided.
- Mount the bridge to ensure equipotentiality of the grounds between the drive and the EMC plate.
- Then mount the IP31 or NEMA type 1 cover on the EMC plate using the screws provided.
Position of the charging LED
Before working on the drive, turn it off, wait until the red capacitor charging LED has gone out, then measure the DC bus voltage.
Position of the capacitor charging LED
Procedure for measuring the DC bus voltage
The DC bus voltage can exceed 1000 V c. Use a properly rated voltage sensing device when performing this procedure. To measure the
DC bus voltage:
1 Disconnect the drive power supply.
2 Wait for the capacitor charging LED to go off.
3 Measure the voltage of the DC bus between the PA/+ and PC/- terminals to check whether the voltage is less than 45 V c.
Refer to page 25 for the layout of the power terminals.

Wiring recommendations
Power
The drive must be connected to the protective ground. To comply with current regulations concerning high leakage currents (above 3.5 mA),
use at least a 10 mm? (AWG 6) protective conductor or 2 protective conductors with the same cross-section as the power section AC supply
conductors.
• Check whether the resistance to the protective ground is one ohm or less. Connect a number of
variable speed drives to the protective ground, as shown in the diagram (see left). Do not lay
protective grounding cables in a loop or in series.
When upstream protection by means of a "residual current device" is required by the installation standards, a type A device should be used
for single phase drives and type B for 3-phase drives. Choose a suitable model incorporating:
• HF current filtering
• A time delay which prevents tripping caused by the load from stray capacitance on power-up. The time delay is not possible for 30 mA
devices. In this case, choose devices with immunity against accidental tripping, for example "residual current devices" with reinforced
immunity from the s.i range (Merlin Gerin brand).
If the installation includes several drives, provide one "residual current device" per drive.
WARNING
IMPROPER WIRING PRACTICES
• The ATV71 drive will be damaged if input line voltage is applied to the output terminals (U/T1,V/T2,W/T3).
• Check the power connections before energizing the ATV71 drive.
• If replacing another drive, verify that all wiring connections to the ATV71 drive comply with all wiring instructions in this
manual.
Failure to follow these instructions can result in death or serious injury.
WARNING
INADEQUATE OVERCURRENT PROTECTION
• Overcurrent protective devices must be properly coordinated.
• The Canadian Electricity Code and the National Electrical Code require branch circuit protection. Use the fuses
recommended on the drive nameplate to achieve published short-circuit current ratings.
• Do not connect the drive to a power feeder whose short-circuit capacity exceeds the drive short-circuit current rating
listed on the drive nameplate.
Failure to follow these instructions can result in death or serious injury.

Wiring recommendations
Keep the power cables separate from circuits in the installation with low-level signals (detectors, PLCs, measuring apparatus, video,
telephone).
The motor cables must be at least 0.5 m (20 in.) long.
Do not immerse the motor cables in water.
Do not use lightning arresters or power factor correction capacitors on the variable speed drive output.
Control
Keep the control circuits away from the power circuits. For control and speed reference circuits, we recommend using shielded twisted
cables with a pitch of between 25 and 50 mm (0.98 and 1.97 in.) and connecting the shielding to ground at each end.
If using conduit, do not lay the motor, power supply and control cables in the same conduit. Keep the metal conduit containing the power
supply cables at least 8 cm (3 in.) away from the metal conduit containing the control cables. Keep the non-metal conduits or cable ducts
containing the power supply cables at least 31 cm (12 in.) away from the metal conduits containing the control cables. If it is necessary for
control and power cables to cross each other, be sure they cross at right angles.

Selecting the encoder
The 7 encoder interface cards available as options with the ATV71 enable three different encoder technologies to be used.
• Optical incremental encoder with differential outputs compatible with the RS422 standard
• Optical incremental encoder with open collector outputs
• Optical incremental encoder with push-pull outputs
The encoder must comply with the following two limits:
• Maximum encoder frequency 300 kHz
• Maximum resolution 10000 points/revolution
Choose the max. standard resolution within these limits to obtain optimum accuracy.
Wiring the encoder
Use a shielded cable containing 3 twisted pairs with a pitch of between 25 and 50 mm (0.98 in. and 1.97 in.). Connect the shielding to ground
at both ends.
The minimum cross-section of the conductors must comply with the table below to limit line voltage drop:

supply for the LIs
• SW1 switch set to "Int Sink" position • SW1 switch set to "Ext Sink" position
WARNING
Unintended Equipment Operation
• When the SW1 switch is set to "Int Sink" or "Ext Sink", the common must never be connected to ground or the protective
ground, as there is then a risk of accidental starting on the first insulation fault.
Failure to follow these instructions can result in death or serious injury.

Connection of several drives in parallel on the DC bus
Connection in parallel on the DC bus is recommended in applications for which full motor power must be guaranteed.
Connection on DC bus between drives with equivalent ratings
Each drive uses its own charging circuit
Drives , and must not be more than one size apart when they are connected in this way.

Operation on an IT (Isolated or impedance grounded neutral) system
IT system: Isolated or impedance grounded neutral.
Use a permanent insulation monitor compatible with non-linear loads: a Merlin Gerin type XM200 or equivalent.
Altivar 71 drives feature built-in RFI filters. These filters can be isolated from ground for operation on an IT system as follows:
ATV71H D55M3X to D75M3X and ATV71H D90N4 to C11N4:
ATV71H C13N4 to C16N4:
CAUTION
When the filters are disconnected, the drive switching frequency must not exceed 4 kHz. Refer to the programming
manual for the corresponding parameter setting.
Failure to follow these instructions can result in equipment damage.

Electromagnetic compatibility, wiring
Electromagnetic compatibility
Principle
• Grounds between drive, motor and cable shielding must have "high frequency" equipotentiality.
• Use of shielded cables with shielding connected to ground at both ends for the motor cables, braking resistor (if used) and control-signal
wiring. Conduits or metal ducting can be used for part of the shielding length provided that there is no break in continuity.
• Ensure maximum separation between the power supply cable (line supply) and the motor cable.

1 Altivar 71
2 Sheet steel grounded plate
3 Metal clamps
4 Shielded cable for motor connection, with shielding connected to
ground at both ends. The shielding must be continuous and
intermediate terminals must be in EMC shielded metal boxes.
5 Shielded cable for connecting the braking resistor (if used).
The shielding must be continuous and intermediate terminals must
be in EMC shielded metal boxes.
6 Shielded cables for connecting the control-signal wiring. For
applications requiring a large number of conductors, use cables with
a small cross-section (0.5 mm2).
7 Shielded cables for connecting the "Power Removal" safety
function input. The shielding must be continuous and intermediate
terminals must be in EMC shielded metal boxes.
8 Shielded cables for connecting the encoder. The shielding must be
continuous and intermediate terminals must be in EMC shielded
metal boxes.
9 Non-shielded wires for relay contact output
10 Connection to the protective ground
11 Non-shielded power supply wires or cable
Note:
• If using an additional input filter, it should be installed under the drive and connected directly to the line supply via an unshielded cable.
Link 4 on the drive is then via the filter output cable.
• The HF equipotential ground connection between the drive, motor and cable shielding does not remove the need to connect the PE
protective conductors (green-yellow) to the appropriate terminals on each unit.
