4 Wiring of the assembly kit
The assembly kit is already wired for operation. Wirings have still to be done by the user (op-
tional modules, see "Assembly kit, wiring diagram").
4.1 Current distribution within the assembly kit
4.1.1 HIMA devices for current distribution
It is recommended to use the HIMA supplies and current distributions:
4.1.2 Supply 24 VDC
The 24 VDC power supply can be feeded three times to the system H51q-MS (starlike wiring).
See also catalog H41q/H51q, chapter 4.3, The Input/Output Level, 24 VDC Supply and Distri-
bution.
4.1.3 Output 24 VDC
With installation of the assembly kit a conductive connection to the
frame or a separate earth connection has to be installed according to
the EMC requirements. Connection PE earth: Faston 6.3 x 0.8 mm.
Pay attention for the manufacturers information concerning detaching
and replugging of the Faston connectors!
