4 Electrical Connection

Assembly work must only be carried out under gas-free conditions!
Consider static electricity instructions (ESD)!

4.1 Wiring

•
The technical requirements and regulations for wiring, electrical safety, as well as project specific and
environmental and local conditions etc. must be observed when mounting.
•
We recommend the following cable types
Power supply 230 V
Alarm message 230 V (also possible together with power supply)
Signal message, bus connection, warning devices 24 V
Possibly connected external analog transmitters
1
The recommendation does not consider local conditions such as fire protection etc.
•
Use copper conductors only for the terminal is only for connection to copper wire.
•
Avoid any influence of external interferences by using shielded cables for the bus line, but do not
connect the shield.
•
Remove the cable isolation as short as possible. It is important to ensure that bare wires, e.g. wire
shields do not come into contact with the mounted PCB (risk of short-circuit).
•
Low voltage wire and mains connected wire must be fixed separately by cable ties or similar, to secure
against looseness.
•
Analog sensors are connected directly to the spring type terminals of the module. The correct polarity
must be observed.
•
The alarm signals are available as voltage-free change-over contacts. If required, the voltage supply is
available at the terminal L.
The exact position of the terminals for the sensors and alarm relays is shown in the connection diagrams.
