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 PCD module is connected to a higher voltage (50 ... 250 V), approved compo-

nents 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 PCD is

disconnected from the power supply.
