4. Commissioning
After unpacking the module search for damage based on ex-
ternal influences. In case of mechanical deformation do not
put the module in operation. The module is mounted into the
subrack with 4 frontside screws.
Please check the input voltage level and compare it with the
type lable value on the inverter module before connecting DC
voltage.
For mounting of the units and putting into operation onsite.
Following instructions and rules have to be observed:
mount in dry, dustfree rooms only
observe the specifications about ambient conditions such
as ambient temperature or relative humidity
highly dusty or aggressive chemical atmosphere is not al-
lowed; dew and dust together can cause short
circuits on printed circuits
sufficient air cooling is required, especially when mount-
ing in cabinets with several 19 subrack levels
Check DC voltage before connecting the inverter (observe
nominal values on type label).
For connection of DC input and AC output the backside panel
connector have to be used. The DC input is protected against
wrong polarity (unit does not switch on). The UNV is
equipped with input and output fusing (MCB`s on front
panel).
The inverters (1.2 to 5.0kVA) operates with temperature
controlled fan cooling. The ambient temperature has to be
lower than 40 °C.
Please check the load power before connecting the module.
A permanent overload is not allowed and decreases the in-
