3 INSTALLATION AND CONNECTION
3.1 MECHANICAL INSTALLATION
3.1.1 Environmental Conditions
Avoid:
 Direct exposure to sunlight.
 Inflammable or corrosive liquids or gases.
 Dust, metallic particles or oil mist.
Environmental conditions permitted for the operation of the drive:
 Temperature surrounding the inverter: from 0 ºC (32 °F) to the rated temperature
specified as follows:
40 ºC (104 °F) – Nema4x/IP66 (mounted on the wall).
50 ºC (122 °F) – Nema4x/IP66 (mounted integrated on the motor).
 For temperatures surrounding the inverter higher than the specifications above, it is
necessary to apply a derating on the current of 2 % for each Celsius degree ( or 1.11
% each °F), limited to an increase of 10 ºC (50 °F).
 Air relative humidity: 5 % to 90 % non-condensing.
 Maximum altitude: up to 1000 m (3,300 ft) - standard conditions (no derating required).
 From 1000 m to 4000 m (3,300 ft to 13,200 ft) current derating of 1 % each 100 m
(or 0.3 % each 100 ft) above 1000 m (3,300 ft) altitude.
 From 2000 m to 4000 m (6,600 ft to 13,200 ft) maximum voltage reduction (480 V for
380…480 V models) of 1.1 % for each 100 m (330 ft) above 2000 m (6,600 ft) altitude.
 Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution.
Condensation must not originate conduction through the accumulated residues.
3.1.2 Positioning and Mounting
The external dimensions, the net weight (mass) of the drive and the suggested torque
values are presented in figure B.1 of Appendix B.
Integrate the motor
For assembling of the drive onto the motor follow the step by step guide in figure C.1
of Appendix C.
Wall mounted
For assembling of the drive in the wall follow the step by step guide in figure C.2 of
Appendix C.
ATTENTION!
Provide independent conduits for the physical separation of signal, control,
and power cables (refer to section 3.2 - Electrical Installation).
