Connecting the supply voltage
NOTICE
Risk of damage to the device!
The device can become damaged if it is connected to a voltage supply that is already
switched on.
•
Only connect the device when the supply cable is de-energized.
The device must be connected to a power supply unit with the following properties:
•
Supply voltage DC 10.8 V – 28.8 V (SELV/PELV as per currently valid standards)
•
Electricity source with at least 3 W power
To ensure protection against short-circuits/overload in the customer’s supply cables,
the wire cross-sections used must be appropriately selected and protected.
