Electrical connections

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 name plate and the technical specifications (see "Technical Specifications" chapter and/or
data sheet).
Important
The electrical connection is carried out with the transmitter in the installed state.
The signal cable wires must be provided with wire end sleeves.
The cross-head screws of the connection terminals are tightened with a size 1 screwdriver
(3.5 mm or 4 mm).

Conductor material

• Standard conductor material must be used for the power supply cable.
• The maximum peripheral wire cross section is 2.5 mm
Notice! Potential damage to parts!
A rigid conductor material can result in wire breaks.
The connecting cable must be flexible.
Line length
From the lower edge of the housing (no cable gland) to the hole in the clamping area, an
additional 100 mm of line is needed. An overall line length (without cable gland) of approx. 200
mm is required (approx. 100 mm bared).
