10.Check internal mains connector plug
Q
is plugged into the
correct socket for the supplied mains voltage (115 V [upper
socket] or 230 V [lower socket]).

— 230 V (lower socket)
11.Proceed to page 16 to make signal connections.
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.
