3.1 Electrical connection
The electrical connection and initial start-up must only be carried out by
qualified electricians according to the following wiring diagrams.
- The relevant standards, safety regulations (e.g. DIN VDE 0100), as well as
the technical connection conditions of energy suppliers must be adhered to!
3.2 Wiring diagram SS-1361 for FWS 2
The fireman's switch is completely ready-for-connection and tested, and all connections
are made to the connection terminals.
The switching contacts can be read directly from the fireman's switch. Furthermore, the-
re is the possibility to connect multiple fireman's switches in a row. An end module/
terminating resistor must be placed in the last fireman's switch.
