3 INSTALLATION AND CONNECTION

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 of CFW-11 inverters with degree of protection IP2X or Nema1: from -10 ºC to 50 ºC (104 °F to
122 °F) - rated conditions (measured around the inverter).
Temperature of CFW-11 inverter with degree of protection IP55: from -10 ºC to 40 ºC (50 °F to 104 °F)
- rated conditions (measured around the inverter).
Current derating according to the ambient temperature:
CFW-11 inverters with degree of protection IP2X or Nema1: from 50 ºC to 60 ºC (122 °F to 140 °F) -
current derating of 2 % for each degree Celsius above 50 ºC (122 °F).
CFW-11 inverters with degree of protection IP55: from 40 ºC to 50 ºC (104 °F to 122 °F) - current derating
of 2 % for each degree Celsius above 40 ºC (104 °F).
Humidity: from 5 % to 95 % non-condensing.
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) altitude. From 2000 m to 4000 m (6,600 ft to 13,200 ft) - maximum voltage (240 V for
models 220...240 V and 480 V for models 380...480 V) derating of 1.1 % for each 100 m (330 ft) above
2000 m (6,600 ft).
