This chapter provides information on installing and wiring the CFW-11.
The instructions and guidelines listed in this manual shall be followed
to guarantee personnel and equipment safety, as well as the proper
operation of the inverter.

3.1 MECHANICAL INSTALLATION

3.1.1 Installation Environment

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 ºC to 50 ºC (14 ºF to 122 ºF) for frame sizes B, C and D models.
- 10 ºC to 45 ºC (14 ºF to 113 ºF) for frame sizes E, F and G models.
- 10 ºC to 40 ºC (14 ºF to 104 ºF) for frame size H.
From 40 ºC to 45 ºC (104 ºF to 113 ºF) for frame size H: 1 % of current derating for each Celsius degree
above maximum temperature as specified in item above.
From 50 ºC to 60 ºC (122 °F to 140 °F) for frame sizes B, C and D models and from 45 ºC to 55 ºC (113
ºF to 131 ºF) for frame sizes E, F, G and H models: 2 % of current derating for each Celsius degree above
maximum temperature as specified in item above.
Altitude: up to 1000 m (3.300 ft) above sea level - standard conditions (no derating required).
From 1000 m to 4000 m (3.300 ft to 13.200 ft) above sea level - 1 % of current derating for each 100 m
(330 ft) above 1000 m (3.300 ft) altitude.
