Requirements and Procedures for
Electrical Connection
WARNING!
Please observe the relevant national safety regulations for the
construction and operation of electrical installations as well as the
following safety instructions.
Before connecting the power supply, check that the operating voltage
on the rating plate is the same as the mains voltage.
The protective-conductor terminal must be connected to a protective
conductor before any other connections are set up.
The device can be dangerous if the protective conductor is interrupted
inside or outside the device or the protective-conductor terminal is
disconnected.
WARNING!
You must be able to disconnect the device from the power supply! For
this purpose, install a 2-pin mains isolator in the power supply line,
since the device does not have its own power switch.
NOTE
Lay the signal lines separate from the power supply lines. Carefully plan
the combination of signal lines in cables.
