3.4.2 Connecting the electric cables
Warning
• Use only PELV circuits as per IEC/EN 60204-1 (protective
extra-low voltage, PELV) for the electric power supply.
• Also observe the general requirements for PELV circuits
in accordance with IEC/EN 60204-1.
• Only use power sources which guarantee reliable electrical
isolation of the operating voltage as per IEC/EN 60204-1.
Protection against electric shock (protection against direct
and indirect contact) is guaranteed in accordance with
IEC/EN 60204-1 by using PELV circuits (electrical equipment
of machines, general requirements).
Note
Check within the framework of your EMERGENCY STOP
circuit to ascertain the measures necessary for putting
your machine/system into a safe state in the event of an
EMERGENCY STOP (e.g. switching off the operating voltage
for the valves and output modules, switching off the
compressed air).

Instructions on connecting the electric elements of the MP A-S
valve terminal with multi-pin plug connection can be found in
the package insert.
MPA-F valve terminal with CPX terminal:
Instructions on connecting the operating voltage can be
found in the system description of your CPX terminal.
Detailed instructions on connecting the CPX modules
(bus node, I/O modules etc.) can be found in the relevant
descriptions for the CPX module (see the system description
