3 INSTALLATION AND CONNECTION

This chapter describes the procedures for the electrical and mechanical installation of the CFW-11M and
CFW-11W G2 RB. The directions and suggestions must be observed to ensure the safety of people and
equipment and the proper operation of the inverter.

3.1 AIR-COOLED UP11 G2 MECHANICAL INSTALLATION

The power units must be installed in the drive panel appropriately, allowing easy extraction and reinstallation in
case of maintenance. The mounting must be such to avoid damage during the panel transportation.

3.1.1 Environmental Conditions

Avoid:
Direct exposure to sunlight, rain, excessive moisture or marine environment.
„
Inflammable or corrosive liquids or gases.
„
Excessive vibration.
„
Dust, metal particles or oil suspended in the air.
„
Permissible environment conditions for operation:
Ambient temperature: 0 °C to 45 °C (32 ºF to 113 ºF) - rated conditions (measured around the inverter). From
„
45 ºC to 55 ºC (113 ºF to 131 ºF) - 2 % of current derating for each Celsius degree above 45 ºC (113 ºF).
Maximum altitude: up to 1000 m (3.300 ft) – rated conditions.
„
From 1000 m to 4000 m (3.300 ft to 13.200 ft) – 1 % of current derating for each 100 m (330 ft) above 1000 m
„
(3.300 ft) of altitude.
From 2000 m to 4000 m (6.600 ft to 13.200 ft) - maximum voltage (480 V for models 380...480 V and 690 V for
„
models 500...690 V) derating of 1.1 % for each 100 m (330 ft) above 2000 m (6.600 ft).
Maximum altitude of 4000 m (13.200 ft).
„
Air relative humidity: 5 % to 95 % non-condensing.
„
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution. Condensation must
„
not cause conduction of the accumulated residues.

3.1.2 Part List

For the panel mounting of the CFW11M G2 RB, it is necessary: UC11RB G2 control set, UP11 G2 power units,
synchronism transformers and cable set to connect the UC11RB G2 to the UP11 G2.
