The following commissioning steps must be carried out after connecting the unit
(as detailed in Chapter 3):
♦ Set the rated mains voltage with S1 (Piano DIP switch) (press the corresponding lever of the switch towards
the module). It is only permissible to select one voltage (S3 also open).
The 200 V voltage range is activated by closing DIP-fix jumper S3 (by means of S1), whereby all the levers
of S1 must be open.
Works setting: for 200-230V and 380-480V units = 400V
for 500-600V units = 500V
♦ The status of the bridging relays can be switched through to the "Warning" output (terminal X36) with the
jumper S2 (DIP-Fix). When S2 is open, the "Warning" relay is opened only in the event of the excess
temperature pre-warning.
Works setting: S2 open
♦ Switch on the mains and electronic power supply.
♦ Enable the converter.
