} Sufficient fuse protection must be provided on all output contacts with inductive loads.
} The safety system and input circuits must always be supplied by a single power supply.
The power supply must meet the regulations for extra low voltages with protective sep-
aration (SELV, PELV).
} Test pulse outputs are used to detect shorts between the inputs. Shorts between inputs
are detected if the inputs are connected to different test pulses (test pulse 0 ... test
pulse 3). Shorts between inputs of the same module with the same test pulses will not
be detected.
} Test pulse outputs must exclusively be used to activate the inputs. They must not be
used to drive loads.
Do not route the test pulse lines together with actuator cables within an unprotected
multicore cable.
} The maximum permitted total current of the test pulse outputs is 640 mA.
Connection
Procedure:
} Connect the supply voltage for the control system:
– Terminal 24 V: + 24 VDC
– Terminal 0 V: 0 V,
} Protect the supply voltage as follows:
– Circuit breaker, characteristic C - 6 A
or
– Blow-out fuse, slow, 6A
