WARNING:
Although some instruments have internal fuse protection, you must use a suitably
rated external protection device, such as a fuse or miniature circuit breaker (
MCB)
.
Switch
off
the power supply and any high-voltage operated control circuits before
making any connections.
The equipment operates on alternating current electricity. Always take suitable safety precautions to
avoid the possibilities of an electric shock.
2.5 SENSOR
UNIT
The prefabricated, eight-conductor cable connecting the sensor unit to the
transmitter unit arrives in place from our factory. We’ve provided this
service to assist you to avoid opening the junction box, which could admit
moisture.
You may mount the transmitter either next to the sensor unit or up to 330 feet
(100 meters) away. Also allow sufficient space on the transmitter unit’s left-
hand side. The access plate and holes on the left side allow room for the
connection of cables to the unit.
Extend the cable by placing a junction box adjacent to the sensor unit, and by
using the required length of 8-conductor cable. You can specify the length of
interconnect cable you’ll need at the time of order.
