6.2 Wiring
6.2.1 Supply and signals
The power supply L+ and M24 from the W row is screw - terminated on the
1L+ and M24 screw terminals. The second 1L+ is wired to the two fuses
(16 A and 4 A). The fused voltages PM (4 A) and L+ (16 A) are screw-faste-
ned on the respective press-fit nuts. Here you also find the connector for the
round cable which is wired to the M7 power supply.
The 5-V bus supply from TPM 478-2 is terminated on the 5 V and 0 V termi-
nals.
Here you also interconnect 0V and M24 if this connection does not exist at
another location (0-V block). (Mandatory connection!)
Existing MZ or BS can be terminated on the respective press-fit nuts.

A patch cord equipped with sub-D connectors on both ends is used to connect
Process Control Monitoring signals, inserted and secured on X30.
The load power supply L+ - of the DIO module is routed across a so-called
“Multi-Fuse”, in order to separate the system from the DIO if an error occurs
( e.g. short-circuit in the DIO connector).
Outputs are available on the screw terminals X31, X32 and X33, inputs on
X35, X36 and X37.
All cables are routed through the front and rear cable duct and, as far as re-
quired, secured in appropriate places with cable ties.
The power supply modules 6DS1000-... inserted in the EUs serve two major
purposes:
Supply of one or multiple EUs with fused L+ and PM,
as well as for the supply of modules via +5 V bus.
After installation of the PCS7/TM, you must switch off the front panel PS
switches for the +5 V bus system of 6DS1000. The assigned error LED is
irrelevant (can be covered up).
