3 INSTALLATION AND CONNECTION
This chapter provides information on installing and wiring the CFW-11 RB. 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 converter.
3.1 MECHANICAL INSTALLATION
3.1.1 Installation Environment
NOTE!
The converter is 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.
„
Condições ambientais permitidas para funcionamento do conversor:
Temperature (standard conditions (surrounding the converter), no frost allowed):
„
- 10 ºC to 45 ºC (14 ºF to 113 ºF) for frame sizes E, F and G (except 720T4 and 760T4 models).
- 10 ºC to 40 ºC (14 ºF to 104 ºF) for frame size G (only 720T4 and 760T4 models).
From 40 ºC to 45 ºC (104 ºF to 113 ºF) for frame size G (only 760T4 model): 1 % of current derating for each
„
Celsius degree above maximum temperature as specified in item above.
From 40 ºC to 45 ºC (104 ºF to 113 ºF) for frame size G: (only 720T4 model): 2 % of current derating for each
Celsius degree above maximum temperature as specified in item above.
From 45 ºC to 55 ºC (113 ºF to 131 ºF) for frame sizes E, F and G: apply 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.
From 2000 m to 4000 m (6.600 ft to 13.200 ft) above sea level - reduction of maximum voltage (230 V for
220...230 V models, 480 V for 380...480 V models, 600 for 500...600 V models and 690 for 660...690 V models)
of 1.1 % for each 100 m (330 ft) above 2000 m (6.600 ft).
Humidity: from 5 % to 95 % non-condensing.
„
Pollution degree: 2 (according to EN50178 and UL508C) with non-conductive pollution. Condensation shall
„
not originate conduction through the accumulated residues.
