3 INSTALLATION AND CONNECTION
This chapter provides information on installing and wiring the CFW-11M G2. 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
The power units must be installed in the drive panel appropriately, allowing easy extraction and reinstallation in
case of maintenance. The mounting must be such to avoid damage during the panel transportation.
3.1.1 Environment Conditions
Avoid:
Direct exposure to sunlight, rain, high humidity, or sea-air.
Inflammable or corrosive liquids or gases.
Excessive vibration.
Dust, metal particles or oil suspended in the air.
Environment conditions for the operation of the inverter:
Ambient temperature: 0 °C to 45 °C (32 °F to 113 °F) - rated conditions (measured around the inverter). From
45 ºC to 55 ºC (113 °F to 131 °F) - 2 % of current derating for each Celsius degree above 45 ºC (113 °F).
Altitude: up to 1000 m (3.300 ft) above sea level – 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) of altitude.
From 2000 m to 4000 m (6.600 ft to 13.200 ft) - maximum voltage (480 V for models 380...480 V and 690 V for
models 500...690 V) derating of 1.1 % for each 100 m (330 ft) above 2000 m (6.600 ft).
Maximum altitude of up to 4000 m (13.200 ft).
Air relative humidity: 5 % to 95 % non-condensing.
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution. Condensation must
not cause conduction of the accumulated residues.
3.1.2 List of Components
For panel mounting of the CFW11M G2, it is necessary: a control set (UC11 G2), UP11 G2 power units and a cable
set to connect the UC11 G2 to the UP11 G2.
,
and
present the list of components of the CFW-11M G2 inverter.
