3.3 Power Controller
If the heater used is more than 15 kW, an
additional contactor is needed. The
contactor unit is linked to the main Power
Controller with a RJ12 cable (Fig.5).
3.4 Contactor Unit
The heater is connected to the electrical
network semi-stationarily with a H07RN-F
rubber cable or its equivalent. The use of
PVC-insulated cable as a connecting cable
is prohibited due to thermal embrittlement.
The maximum distance of the junction box
from the floor is 400 mm, measured from
the upper corner of the box.
