INSTALLATION AND CONNECTION
This chapter describes the procedures for the electrical and mechanical installation of the CFW-11W Modular
Drive. The directions and suggestions must be observed so as to ensure the safety of people and equipment,
and the proper operation of the inverter.
2.1.
ENVIRONMENTAL CONDITIONS
Avoid installing the CFW-11W in areas with:
Direct exposure to sunlight, rain and high humidity
Inflammable or corrosive gases or liquids
Excessive vibration
Dust, metallic particles and oil mist.
Environment conditions for the operation of the inverter:
Ambient temperature: 0 °C to 40 °C (32 °F to 104 °F) – nominal conditions (measured around the
inverter). 40 °C to 45 °C (104 °F to 113 °F) – current derating of 2 % for each 1 °C (1.8 °F) above 40 °C
(104 °F).
Coolant input temperature: 0 ºC to 40 ºC (32°F to 104°F) according to the coolant used. 40 ºC to 45 ºC
(104 °F to 113 °F) – current derating of 3 % for each 1 °C (1.8 °F) above 40 ºC (104 °F)
Coolant flow: 20 l/min.
Air relative humidity: 5 % to 90 % non-condensing.
Maximum altitude: up to 1000 m (3,300 ft) – nominal conditions. 1000 m to 4000 m (3,300 ft to 13,200
ft) – current derating of 1 % for each 100 m (or 0.3 % each 100 ft) above 1000 m (3,300 ft). 2000 m to
4000 m (6,600 ft to 13,200 ft) – maximum voltage derating of 1.1 % for each 100 m (or 0.33 % each
100 ft) above 2000 m (6,600 ft). Maximum altitude up to 4000 m (13,200 ft).
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution. Condensation
shall not originate conduction through the accumulated residues.

COMPONENT LIST
The kit for panel mounting is composed of the control set and the UP11 power units, whose number varies
according to the current. The control set contains the UC11 control unit, the cable sets required for wiring the
IPS board to the power units and the ribbon cable that connects the IPS board to the CC11 control board.
