3 INSTALLATION AND CONNECTION
3.1 MECHANICAL INSTALLATION
3.1.1 Environmental Conditions
Avoid:
Direct exposure to sunlight.
„
Inflammable, corrosive liquids or gases.
„
Metallic particles or oil mist.
„
Environmental conditions permitted for the operation of the inverter:
Ambient temperature surrounding the inverter: from 0 ºC (32 °F) until:
„
40 ºC (104 °F) - Nema4x/IP66 (mounted on the wall).
50 ºC (122 °F) - Nema4x/IP66 (mounted integrated on the motor).
40 ºC (104 °F) - Nema4x/IP66 mounted integrated on the motor (Refer to
208).
40 °C (104 ºF) - Nema4x/IP66 (inverter including safe stop module).
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 of
„
current).
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.
