WARNING – THIS APPLIANCE MUST BE EARTHED
Verify that the electrical supply cable is sufficient for the rated loading.
Check that the incoming supply conforms to the rated supply.
The heater power circuit must be protected by a suitably rated over
current device.
The supply cables used must be suitable for hazardous area installation,
and for the temperature stated on the rating plate. They must be
connected to the heater using ATEX certified EEx d cable glands
designed for use with a female M20x1.5 parallel thread to BS ISO
262:1998.
Where the cable entry requires an adaptor, for size reduction, a suitable
ATEX certified EEx d adaptor must be used.
If the supply cable is housed in a conduit, to protect wiring, a suitable
ATEX certified EEx d adaptor must be used.
The incoming cables must be connected to the factory fitted heater
terminals provided. Do not alter any factory fitted wiring.
Before energising the heater for the first time, ensure that the insulation
resistance is at least 2 M
The heater is supplied with an earth stud, located inside the terminal box,
which must be connected to earth.
After connection check the continuity of earth connections.
