4. Electrical connection
Wiring must only be carried out with power off!
Provide standed wires with ferrules.
Check all lines and connections before swit-
ching on the equipment.
Interference and distortion
All connections are protected against the effects
of interference. The location should be selec-
ted to ensure that no capacitive or inductive
interferences can affect the sensor or the
connection lines! Interference can be caused
by motors, switch gear, cyclic controls and
contactors. Suitable wiring layout and choice of
cable can minimise the effects of interference.
The sensor should be positioned well away from
cables with interference; if necessary a protec-
tive screen or metal housing must be provi-
ded. The running of wiring parallel to the mains
supply should be avoided.
Power supply
The unit is battery-powered. EG10 version has
external power supply through connection cable
and enclosed battery box. TF and TS casing is
with integral battery box.
