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

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: -10 ºC to 45 ºC (14 °F to 113 °F) - standard conditions (surrounding the inverter).
From 45 ºC to 55 ºC (113 °F to 131 °F) - current derating of 2 % each °C (or 1.11 % each °F) above 45 ºC
(113 °F).
Inverters CFW-11 with IP55 degree protection: -10 ºC to 40 ºC (14 °F to 104 °F) - standard conditions
(surrounding the inverter).
From 40 ºC a 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.
Altitude: up to 1000 m (3,300 ft) - standard conditions (no derating required).
From 1000 m to 4000 m (3,300 ft to 13,200 ft) - apply current derating of 1% for each 100 m (328 ft) above
1000 m (3,300 ft) of altitude.
From 2000 m to 4000 m (6,600 ft to 13,200 ft) - apply maximum voltage derating (240 V for models 220...240 V ,
and 480 V for models 380...480 V) of 1.1 % for each 100 m (328 ft) above 2000 m (6,600 ft).
Pollution degree: 2 (according to EN50178 and UL508C) with non-conductive pollution. Condensation
shall not originate conduction through the accumulated residues.
