ECHNICAL

 

DATA

) does not 

exceed the maximum switching voltage of the relay (see technical data of the 
relay).

NOTE

installation

notes

Observe the following points when attaching connecting wires to the terminal 
strip:

Shorten all the wires to be used to the length required for the installation

Always fit all the ends of the wires with wire end sleeves before connecting 
them to the terminal strip

Any wires that are not used and project into the housing must be cut off as 
closely as possible to the cable gland.

Close all unused cable glands with blind plugs.
