DANGER! Mains voltage
When wiring the electric power supply line, ensure that the double or reinforced insulation between
the electric circuits and the secondary circuit remains intact.
NOTICE! Mains voltage
The additional insulation must be suitable for a test voltage of 1500 VAC. The insulation must be at
least 0.4 mm thick
e.g. insulation hose, type BIS 85 from Bierther GmbH.
The additional insulation of the power cables (mains connection, alarm and signalling relays) can be implemented as follows:
1
- Terminals (plug-type connectors)
2
- Flexible insulating tubing for the power cables
3
- Connecting cable
