3 INSTALLATION AND CONNECTION
This chapter describes the electrical and mechanical installation procedures for the CFW11W G2. The directions
and suggestions must be observed so as to ensure the safety of people and equipment, and the proper operation
of the inverter.
3.1 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 Environment Conditions
Avoid:
„
Direct exposure to sunlight, rain and high humidity.
„
Inflammable or corrosive liquids or gases.
„
Dust, metal particles or oil suspended in the air.
Environment conditions permitted for operation:
„
Ambient temperature: 0 °C to 45 °C (32 °F to 113 °F) - rated conditions (measured around the inverter). From
45 ºC to 55 ºC (113 °F to 131 °F) - 0.5 % of current derating for each Celsius degree above 45 ºC (113 °F).
„
Coolant input temperature: 0 ºC to 45 ºC (32 °F to 113 °F) according to the coolant used. From 45 ºC to 55 ºC
(113 °F to 131 °F) – 1 % of current derating for each Celsius degree above 45 ºC (113 °F).
„
Coolant flow: 20 l/min.
„
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 above 1000 m of altitude.
„
From 2000 m to 4000 m (6.600 ft to 13.200 ft) - maximum voltage (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 CFW11W G2, it is necessary: control set, UP11W G2 power units and cable sets to
connect the UC11 G2 to the UP11W G2.
