3 INSTALLATION AND CONNECTION

This chapter describes the CFW-11 electrical and mechanical
installation procedures. The guidelines and suggestions must be
followed aiming personnel and equipment safety, as well as the
proper operation of the inverter.

3.1 MECHANICAL INSTALLATION

3.1.1 Environmental Conditions

NOTE!
The inverter are designed for indoor use only.
Avoid:
Direct exposure to sunlight, rain, high humidity, or sea-air.
Inflammable or corrosive gases or liquids.
Excessive vibration.
Dust, metallic particles, and oil mist.
Environment conditions for the operation of the inverter:
Temperature (standard conditions (surrounding the inverter), no frost allowed):
- 10 °C to 45 °C (50 °F to 113 °F) for frame sizes F and G (except models 720 A and 760 A).
- 10 °C to 40 °C (50 °F to 104 °F) for frame sizes G (only models 720 A and 760 A) and H.
From 40 °C to 45 °C (50 °F to 113 °F) for frame size G (only model 720 A): 2 % of current derating for each
celsius degree above maximum temperature as specified in item above.
From 40 °C to 45 °C (50 °F to 113 °F) for frame sizes G (only model 760 A) and H: 1 % of current derating
for each celsius degree above maximum temperature as specified in item above.
From 45 °C to 55 °C (113 °F to 131 °F) for frame sizes F, G and H: 2 % of current derating for each Celsius
degree above maximum temperature as specified in item above.
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) (or 0.3 %
each 100 ft) above 1000 m (3.300 ft) altitude.
