4.0 Electrical connection / Wiring diagrams
Isolate the unit fully from the mains electric supply. All work may only be carried out by a qualified person.
All relevant national and international safety and installation regulations are to be adhered to. An appliance is required
for cut off from the supply with a minimum of 3 mm contact opening of each pole. Power supply voltage and frequen-
cy must correspond to the data given on the rating plate. The introduction of the power cable must be done so that in
case of water, entry along the power cable is impossible. The cable may not touch sharp objects. The degree of pro-
tection of the SlimVent models with connected piping system is IP 44.
The electrical connection is carried out at the connecting terminals and in the terminal box IP 55 (pre-assembled).
The assigned wiring diagram SS-934.1 is to be considered (see fig.4).
The electrical connection must be fully isolated from the supply up to the final assembly !
EMV regulation/norm
Important indication for the electromagnetic compatibility
Interference resistance according to DIN EN 55014-2 depending upon impulse form and energy rate of 1000 V to
4000 V. With operation with fluorescent tubes, switch power supplies, electronically regulated halogen bulbs etc. these
values can be exceeded.
In this case additional suppression shielding activities (not provided by Helios) are necessary (L -, C or RC elements,
protection diodes, resistors).
