Installing the heater
CAUTION!
Before installation, check the support tube of the feed arm for sharp edges on the end face of the support tube. If sharp edges
are present on the end face of the support tube, smooth the edges so that the heater strip will not be damaged by them.
Installing a new feed arm heater
Before the heater is slid into the support tube it can be wetted with a lubricant such as a silicone spray or liquid soap. This will make
insertion easier.
Slide the heater into the support tube so that the
heater strip
on the support hose is
at the top
.
Working from the rear (reflector end) of the feed arm, slide the heater into the support tube, starting with the U-bend of the heater
strip. When doing this, slightly compress the support hose.
There is no need to provide additional fastening of the heater within the support tube.
Electrical connection
1. Feed the connection cable of the feed arm heater into the terminal box of the controller and secure it with cable ties. The cable is
then threaded through the cable gland (M16) provided.
2. Before connecting the cable to the controller, check the insulation resistance R
i
of the heater:
Heater no.
Target value Actual value
Insulation resistance Ri
> 999 MΩ
3. The supply to the heater must include an earth leakage circuit-breaker.
CAUTION!
The heater for the feed arm is operated at 230 V.
