Electronics power supply
Terminal type: Type 49 plug-in terminal
Function Connec-
tion
Incoming supply
400V
or
Incoming supply
230V
NOTE
In the case of line voltages which exceed the tolerance range specified in Section 3.4, the
electronics supply voltage, field circuit mains supply connection and converter fan connection
must be adjusted by means of transformers to the permissible value stated in Section 3.4. It is
essential to use an isolating transformer for rated line voltages in excess of 460V.
The rated supply voltage for the armature circuit (index 001) and the field circuit (index 002) must
be set in parameter P078.
Fan
(for forced-cooled converters ≥ 400A)
Terminal type: DFK-PC4 plug-in terminal (screw-type)
The insulation on the supply cables must be taken up to the terminal housing.
Function
Incoming supply 400V bis 460V
PE conductor
or
Incoming supply 230V
WARNING
The converter might overheat if the incorrect phase sequence is connected (incorrect direction
of rotation of fan).
Check:
• On converters up to 850A (fan at bottom), check whether fan is rotating in direction of arrow
• On converters of > 850A (fan at top), check whether fan is rotating in counter-clockwise
direction (to left) when viewed from above
Caution: Rotating parts can cause physical injuries!
