Mains power cables
DANGER – Serious damage to health / risk to life
— The incoming mains supply cable must be isolated or
disconnected at the supply end of the cable before
making power connections at the transmitter and / or
sensor.
– Before making power connections between the
transmitter and sensor, set the sensor power switch
on the transmitter PCB to the OFF position – see
page 16. This internal switch on the transmitter is
NOT a safety isolation switch and is fitted for
operational purposes only.
Referring to Fig. 15:
1. Prepare the incoming power cable and transmitter to sensor
power cable for connection by cutting back the outer PVC
sheathing and wire ends to the dimensions shown below:
5 mm
(0.25 in.)
50 mm
(2.0 in.)
