INSTALLATION, CONNECTION AND ENERGIZATION
Allowed environmental conditions:
Temperature: From 0 ºC to 40 °C (32 °F to 140 °F) - nominal conditions (no derating required).
From 40 °C to 50 °C (140 °F to 122 °F): current reduction of 2.5 % for each Celsius degree above 40 °C (140 °F).
Relative humidity: from 5 % to 90 % non-condensing.
Altitude: up to 1000 m (3.300 ft) - nominal conditions (no derating required).
From 1000 m to 4000 m (3,300 ft to 13.200 ft) - current derating of 1 % each 100 m (or 0.3 % each 100 ft) above 1000 m (3.300 ft)
altitude.
Pollution degree: 2 (according to IEC/UL standards) with non-conductive pollution.
Condensation shall not originate conduction through the accumulated residues.
The medium voltage inverter MVW01 is supplied in form of a panel, whose dimensions are presented in Table 3.1 on page 3-3 . According
to the components mounted in each column and to their function, this complete panel results in in the inseparable union of three functions,
rectifier, inverter and control.
The inverter power arms are supplied separately in their own packing.
Arm dimensions: 360 mm x 1040 mm x 680 mm (width x height x depth).
10.1.2 Handling Recommendations
The inverter package must be removed only at the installation site, where the panel will be operated.
Before hoisting or moving the panel, locate the hoisting eyes and fragile spots in the documentation that comes with the product. Follow the
instructions that come with the panel.
10.1.3 Hoisting
Make sure that the lifting device used to hoist the panel and the arms is suitable for their weight and shape, refer to the Table 10.1 on page 10-2 .

The inverter arms weigh approximately 140 kg (308.6 lb) each arms.
Observe the gravity center and ensure that the hoisting mechanism is adequate and safe.
Use the configuration showed in the Figure 10.1 on page 10-3 .
The cables or chains used for hoisting must be at a minimum angle of 45° regarding the horizontal plane.
Hoisting must be done in a slow and stable manner. Before starting make sure the entire pass is clear of obstacles. If any alteration or damage
in the panel structure is noticed, then abort the hoisting and rearrange the cables or chains.
