Before commissioning
General remarks
Set-up regulati-
ons
The power source is tested to IP21 meaning:
-
protected against ingress of solid bodies with diameters greater than 12.5 mm
(0.49 in.)
- protection against vertically falling drops of water
The power source can be set up and operated outdoors in accordance with IP21. The
built-in electrical parts must however be protected from direct wetting.
The venting duct is a very important safety feature. When choosing the machine locati-
on, ensure that the cooling air can enter and exit unhindered through the air ducts on
the front and back of the machine. Any electroconductive metallic dust (e.g. from
grinding work) must not be allowed to get into the power source.
NOTE! Inadequately dimensioned electrical installations can lead to serious
damage. The mains lead and its fuse protection must be dimensioned in
accordance with the technical data.
The VST 1500 must be operated at a mains voltage of 1x230V~.
The VST 2500 and the VST 3100 can be operated at a mains voltage of 3x230 or
3x400V~. These power sources are set to 400V~ in the factory. The tolerance range of
+/- 10% means they can also be operated at 380 V~ or 415 V~.
Important! As an option, the power source can be designed for a special voltage. The
mains voltage is given on the rating plate.
Utilisation in
