8.2.9 X30 and X31 - Power Supply
X two 6-pole Power CombiCon
Pin Designation
X30
1 L1
Main supply. The intermediate circuit voltage depends on the input voltage. Ex-
ample: 3 x 400 V
AC
-10 %/+20 % for an intermediate circuit voltage of 560 V.
2 L2
3 L3
4 PE earth conductor
5 LL1
Logic voltage supply. The logic voltage supply must always be connected (same
potential as main supply, see "Technical Data“,
page 25
).
6 LL2

must be bridged with REX if no external ballast resistor is existent
1 If an external ballast resistor is used, the wire strap between X31/5 and 6 must
be removed. The external ballast resistor is then connected bUB and
REX.
Warning
LL1 and LL2 must always be connected. The angle pulses and error
messages are kept in case of an EMERGENCY STOP situation. If
the main voltage supply is turned off, make sure that all three mains
phases are also turned off! For this reason a main contactor with po-
sitively driven contacts must be used.
