Cable connection
- Use NYM cable with a customary maximum diameter of 11 mm.
- Remove cable sheath to a length of 135 mm. Strip back each wire's insulation by about 8
mm.
- Carefully slide cable through the grommet.
- The wiring diagram (SS-1080) should always be used to ensure proper wire placement.
- Check sealing of the connection cables and cable wires clamp.
- If mounted at the inlet spout the sheathed cable does not enclose evenly, the spout should
be additionally sealed with silicone. Otherwise, the IP protection will be compromised.
- The connection cable should be positioned in such a way that in case of water entering,
water may not penetrate along the cable. Cables should be laid in such a way that they do not
run over sharp edges.
- Check the fan according to the intended use.
- Supply voltage should match the name plate data.
- Ensure secure mounting and proper electrical installation of the device.
- Check the rotation of the impeller.
- All parts of the fan, especially screws and protective grid must be checked for tightness. Do
not mislay the screws included with the unit!
- Ensure that the necessary protective guard is installed, as the unit cannot be operated
without it.
- During the trial run the fan should be checked for vibrations and noise.
- Power consumption should match the name plate data.
