Installation instructions
For reasons of safety it is not permissible to connect low voltages (up to 50 V) and
higher voltages (50 … 250 V) to the same module.
If a Saia PCD
®
module is connected to a higher voltage (50 … 250 V), approved com-
ponents for this voltage must be used for all elements that are electrically connected
to the system.
Using higher voltage (50 … 250 V), all connections to the relay contacts must be
connected on the same circuit, i.e. in such a way that they are all protected against
one AC phase by one common fuse. Each load circuit may also be protected
individually.
I/O modules and I/O terminal blocks may only be plugged in and removed when the
Saia PCD
®
and the external +24 V are disconnected from the power supply.
