Connecting cable:
3 x 0.22 mm², length 1 m,
plug-in connection
Installation and fitting:
Electrical connection must be carried out in accordance with the
requirements of the local Electricity Board.
The connecting cable must not come into contact with the hot
pipe as excessive heat will accelerate the ageing of the cable
insulation.
When choosing the switching contacts and the network fuses, the
start up of the heating element has to be taken into consideration.
The following cable lengths are recommended for a 24 V
installation:
Cable cross-
section [mm
2
]
2 x 0.22
2 x 0.80
2 x 1.50
When installing several actuators, the indicated length of cable
must be divided by the number of mounted actuators.
A safety transformer according to EN 61558-2-6 must always be
used. Dimensioning of the transformer is determined by the start
up power of the actuators.
