Electrical connections

WARNING – Electrical dangers!
Observe the applicable regulations governing
electrical installation. Connections must only be
established in a dead-voltage state. The
transmitter has no switch-off elements. Therefore,
overcurrent protective devices, lightning
protection, or voltage disconnection options must
be provided at the plant.
Check that the existing operating voltage
corresponds to the voltage indicated on the name
plate.
The same lines are used for both the power
supply and output signal.

Cable connection

Depending on the model supplied, the electrical connection is
established via cable gland M16x1.5 (for diameters of
5 to 10 mm) or M20x1.5 (for diameters of 6 to 11 mm), a
threaded bore for cable gland 1/2-14 NPT, or via the Han 8U
plug, i.e., via the miniature plug connector M12 x 1 (see also
"Technical specification / Electrical connections").
The screw terminals are suitable for wiring cross-sections up
to 1.5 mm².
It is recommended that you strip approx. 30 ... 35 mm
(1.18 ... 1.38 inch) off the cable jacket.

IMPORTANT (NOTICE)
After a period of several weeks, removing the screws
in the housing cover requires increased force. This is
not caused by the threads, but instead is due solely
to the type of seal.
