Electrical connections

Electric shock due to incorrect power pack!
Danger of injury!
The combination modules are permitted to be supplied by the following voltages only:
– 24 V DC SELV or PELV circuits, whereby each of the 24 V DC supply circuits must be
provided with a DC-rated fuse which is capable of opening at a current of 6.67 A in 120 s
or less, or
– 24 V DC circuits which fulfill the requirements of limited-energy circuits according to
clause 9.4 of standard UL 61010-1, 3rd edition, or
– 24 V DC circuits which fulfill the requirements of limited power sources according to
clause 2.5 of standard UL 60950-1, 2nd edition, or
– 24 V DC circuits which fulfill the requirements of NEC Class II according to standard
UL 1310.
Make sure that the power supply of the power pack is always less than 300 V AC (outer
conductor – neutral wire).
The bus coupler supplies the power for the logistics of the combination module via the electrical
backplane connections (13) and (15).
The power supply from X1S serves only to supply the E/P pressure regulators connected to the
combination module. It is present at X2A1, pin 1 and X2A2, pin 1.
The load circuit X1S power supply connection (11) is an M12 plug, male, 4-pin, A-coded.
See Table 10 for the pin assignments of the power supply. The view shown displays the device
connections.
