NOTICE
Phase correct wiring of PCL bus modules
All PCL bus modules turn the phases by
180°! Therefore it’s important to adhere strictly
to the wiring rules described in this chapter!
In order to connect both ends of the power loop to the same phases, the PCL-PC on
the A side has to be connected according to the scheme in Figure 7-1 and the right
connection of the module on the B side depends on the No. of nodes in the power loop.
It has to be connected
- as stated below in Figure 7-2
, if the number of PCL nodes in that power loop is
odd
!
-
as stated in Figure 7-3
, if the number of PCL nodes in that power loop is
even
!
7.3 Power loop interconnection
Figure 7-2: Power supply wiring if the No. of nodes in the power loop is
odd
!
Figure 7-3: Power supply wiring if the No. of nodes in the power loop is
even
!
CAUTION
Malfunction / Damage
Take care that the phases are connected in the right order as visible on the right (B-)
side of the figures!
As described above, the relevant No. of nodes has to be counted in each power loop
(that could differ from the data loop(s)).
