Installation manual
Safety instructions:

For applications with frequent demand for the safety shutdown, testing should be at
short intervals, e.g. at the start of the shift, 1 x per week. However, a test should be
undertaken cyclically at least 1 x per year.

The test function for the outputs is undertaken for group operation and individual
operation. The signal outputs are not tested.

The high-side (Qx_PP) and low-side (Qx_PN) outputs are not allowed to be used
individually for safety tasks. Usage for safety tasks is only permissible in the
combination high-side / low-side (attention: not relevant from firmware release
05-00-00-01)

Mixed operation of the relay contacts is not allowed!
Mixed operation:
with
Example:
INCORRECT: 230 V AC are switched via Q1.1 + Q1.2 and 24 V DC are switched via
Q2.1+Q2.2.
CORRECT: Über Q1.1 + Q1.2 und Q2.1 + Q2.2 werden jeweils 230V AC geschalten.
Or 24 V DC are switched via Q1.1 + Q1.2 and
Q2.2.
The outputs can be loaded as follows:

Safety instructions:

For safety-related applications, only actuators with a holding power > 0.4 W or a load
resistance < 100 Ω are allowed to be used.

A series of diagnostic measures are implemented for the output system. Attention is to
be paid here in particular to the inclusion of elements for switching amplification such
as relays, contactors etc. in the shutdown circuit.
