Danger of injury!
The units 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 seconds 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 cable – neutral wire).
The X1S power supply connection (7) is an M12 plug, male, 4-pin, A-coded.
See Table 7 for the pin assignments of the power supply. The view shown displays the device
connections.

The voltage tolerance for the electronic components is 24 V DC ±25%.
The voltage tolerance for the actuator voltage is 24 V DC ±10%.
The maximum current for both power supplies is 4 A.
The power supplies are equipped with internal electrical isolation.
To discharge the EMC interferences, connect the FE connection (8) on the bus coupler via
a low-impedance line to functional earth.
The line cross-section must be selected according to the application.
