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 installing the inverter in an area with:
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 50 ºC (14 °F to 122 °F) – standard conditions (surrounding the inverter).
From 50 ºC to 60 ºC (122 °F to 140 °F) - 2 % of current derating for each Celsius degree above 50 ºC (122 °F).
Humidity: from 5 % to 90 % 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) - 1 % of current derating for each 100 m (330 ft) above
1000 m (3,300 ft) altitude.
Pollution degree: 2 (according to EN50178 and UL508C) with non-conductive pollution. Condensation shall
not originate conduction through the accumulated residues.
3.1.2 Mounting Considerations
Consult the inverter weight at the table 8.1.
Mount the inverter in the upright position on a flat and vertical surface.
External dimensions and fixing holes position according to the figure 3.1. Refer to the section 8.3 for more
details.
First mark the mounting points and drill the mouting holes. Then, position the inverter and firmly tighten the screws
in all four corners to secure the inverter.
Minimum mounting clearances requirements for proper cooling air circulation are specified in figures 3.2 and 3.3.
Inverters of frames A, B, and C can be arranged side-by-side with no clearance required between them. In this
case, the top cover must be removed as shown in figure 3.3 (b) .
Do not install heat sensitive components right above the inverter.
ATTENTION!
When arranging two or more inverters vertically, respect the minimum clearance A + B (figure 3.2) and
provide an air deflecting plate so that the heat rising up from the bottom inverter does not affect the
top inverter.
