Installation, Connection and Energization
Allowed environmental conditions:
„
Temperature: from 0 ºC to 40 ºC (32 ºF to 140 ºF) - nominal conditions (no derating required).
„
From 40 ºC to 50 ºC (140 ºF to 122 ºF): current reduction of 2.5 % for each Celsius degree above 40 ºC (140 ºF).
„
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 MVW3000 is supplied in form of a panel, whose dimensions are presented in
Table 4.2 on page 4-3 to Table 4.8 on page 4-4 . According to the components assembled in each panel
division and their function, this whole panel results in the inseparable union of four functions: switching and
protection circuit, phase-shifting transformer, power cells and main control.
The inverter power arms are supplied separately in their own packing.
6.1.2 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.
6.1.3 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 6.1 on page 6-2 .

Note: For models above 8 kV (8 cells per phase), the mass information will be supplied on request.
Observe the gravity center and ensure that the hoisting mechanism is adequate and safe. Use the configuration
showed in the
Figure 6.1 on page 6-3 .
