Warning – Electrical voltage risk!
Observe the corresponding instructions for the electrical installation. Only connect in dead-
voltage state!
Since the transmitter has no switch-off elements, overvoltage protection devices, lightning
protection or voltage separation capacity must be provided on the plant side.
Energy supply and signal are routed in the same line and are to be implemented as SELV or
PELV circuit according to norm (standard version). In the ignition-proof version, the guidelines
according to the ignition-proof norms are to be adhered to.
It must be checked whether the existing power supply corresponds with the specifications on
the model plate and in the technical specifications in the “Technical specifications" section or
the data sheet.
Important
The signal cable wires must be provided with wire end sleeves.
The slotted screws of the connection terminals are tightened with a size 1 screwdriver
