Installation regulations and relay contacts
A.3.1
Installation regulations for switching extra-low voltage
For safety reasons, max. voltages of 50V may be switched on this module.
The safety standard relating to the air and leakage current distances between ad-
jacent channels is not stated for this module for higher voltages (50 … 250V).
It should be noted that all connections to the relay contacts of the module… A250
must be connected on the same circuit, i.e. only 1 phase for each module is per-
mitted. The individual load circuits can however be secured individually again.
A.3.2
Installation regulations for switching low voltage
For safety reasons, the extra-low voltage (up to 50V) and low voltage (50… 250V)
may not be connected to the same module.
If a module from Saia PCD
®
Systems is connected to low voltage (50… 250V),
components that are approved for low voltage use must be used for all elements
that are electrically connected to this system.
When using low voltage, all connections to the relay contacts of the module ...A200 must
be connected on the same circuit, i.e. only 1 phase for each module is permitted over 1
shared fuse. The individual load circuits can however be secured individually again.
