NOTE: Please also refer to the Programming Manual.
When the drive is powered up, the power components and some of the control
components are connected to the line supply. It is extremely dangerous to touch
them. The drive cover must be kept closed.
In general, the drive power supply must be disconnected before any operation on
either the electrical or mechanical parts of the installation or machine.
After the ALTIVAR has been switched off and the display has disappeared
completely, wait for 10 minutes before working on the equipment. This is the time
required for the capacitors to discharge.
The motor can be stopped during operation by inhibiting start commands or the
speed reference while the drive remains powered up. If personnel safety requires
prevention of sudden restarts, this electronic locking system is not sufficient: fit
a cut-off on the power circuit..
The drive is fitted with safety devices which, in the event of a fault, can shut down
the drive and consequently the motor. The motor itself may be stopped by a
mechanical blockage. Finally, voltage variations, especially line supply failures,
can also cause shutdowns.
If the cause of the shutdown disappears, there is a risk of restarting which may
endanger certain machines or installations, especially those which must
conform to safety regulations.
In this case the user must take precautions against the possibility of restarts, in
particular by using a low speed detector to cut off power to the drive if the motor
performs an unprogrammed shutdown.
The drive must be installed and set up in accordance with both international and
national standards. Bringing the device into conformity is the responsibility of
the systems integrator who must observe the EMC directive among others within
the European Union.
The specifications contained in this document must be applied in order to
comply with the essential requirements of the EMC directive.
The Altivar 31 must be considered as a component: it is neither a machine nor a
device ready for use in accordance with European directives (machinery
directive and electromagnetic compatibility directive). It is the responsibility of
the end user to ensure that the machine meets these standards.
The drive must not be used as a safety device for machines posing a potential
risk of material damage or personal injury (lifting equipment, for example). In
such applications, overspeed checks and checks to ensure that the trajectory
remains under constant control must be made by separate devices which are
independent of the drive.
The products and equipment described in this document may be changed or
modified at any time, either from a technical point of view or in the way they are
operated. Their description can in no way be considered contractual.

(1)These power ratings and currents are for a maximum ambient temperature of 50°C and a switching frequency of 4 kHz in continuous
operation.The switching frequency is adjustable from 2 to 16 kHz.
Above 4 kHz, the drive will reduce the switching frequency in the event of excessive temperature rise. The temperature rise is controlled
by a PTC probe in the power module. Nonetheless, the nominal drive current should be derated if operation above 4 kHz needs to be
continuous.

Wiring recommendations
Power
The drive must be earthed to conform with the regulations concerning high leakage currents (over 3.5 mA).
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 RCDs with reinforced immunity from the
range (Merlin Gerin brand).
If the installation includes several drives, provide one "residual current device" per drive.
Keep the power cables separate from circuits in the installation with low-level signals (detectors, PLCs, measuring apparatus, video,
telephone).
If you are using cables > 50 m between the drive and the motor, add output filters (please refer to the catalogue).
Control
Keep the control circuits away from the power cables. For control and speed reference circuits, we recommend using shielded twisted
cables with a pitch of between 25 and 50 mm, connecting the shielding to ground at each end.

Operation on an IT system
IT system: Isolated or impedance earthed neutral.
Use a permanent insulation monitor compatible with non-linear loads (a Merlin Gerin type XM200, for example).
pppM2 and N4 drives feature built-in RFI filters. These filters can be isolated from ground for operation on an IT system as follows:
ATV 31
ATV31H018M2 to U22M2 and ATV31H037N4 to U40N4:
Pull out the jumper on the left of the ground terminal as illustrated below.

Principle
• Grounds between the drive, motor and cable shielding must have "high frequency" equipotentiality.
• Use shielded cables with shielding connected to ground throughout 360° at both ends for the motor cable 6, braking resistor (if used) 8,
and control-signalling cables 7. Metal ducting or conduit 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.

4 Non-shielded wires for relay contacts
5 Fix and ground the shielding of cables 6, 7 and 8 as close as possible to the drive:
- Strip the shielding.
- Use stainless steel cable clamps of an appropriate size on the parts from which the shielding has been stripped, to attach them to the
plate 1.
The shielding must be clamped tightly enough to the metal plate to ensure correct contact.
6 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.
For 0.18 to 1.5 kW drives, if the switching frequency is higher than 12 kHz, use cables with low linear capacitance: max. 130 pF
(picoFarads) per metre.
7 Shielded cable for connecting the control/signalling wiring.
For applications requiring several conductors, use cables with a small cross-section (0.5 mm
2
).
The shielding must be connected to ground at both ends. The shielding must be continuous and intermediate terminals must be in EMC
shielded metal boxes.
8 Shielded cable for connecting braking resistor (if fitted).
The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes.
Note:
• If using an additional input filter, it should be mounted under the drive and connected directly to the line supply via an unshielded cable.
Link 3 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.
