DANGER
Earth conductor not properly connected
Danger of death from electric shock!
▷
Never operate the motor without earth conductor.
▷
The earth conductor must be connected by a professional electrician only.
NOTE
The motor lead is selected for submerged operation and must be completely
submerged, including the cable connector.
See order documentation for any other use!
For pump sets installed in VdS-approved sprinkler installations always refer to and
observe the applicable requirements stipulated by VdS (German association of
property insurance companies). In accordance with VdS 2025, the cable must be laid
in such a way that it is protected against short circuit and earth fault.
NOTE
Before fitting the submersible cable to the motor verify that the cable entry is clean
and dry. Apply a non-conductive silicone paste to the rubber elements of the cable
connector to facilitate assembly.
Submersible motors are supplied fitted with a motor lead. The motor lead has been
extended with a suitably sized extension cable to meet the length required for the
specific installation. Unless otherwise indicated, the motor lead is designed for
submerged operation only. To meet this condition the cable connector also has to be
completely submerged.
Extension cables connected by KSB
If agreed with KSB, the extension cable can be supplied connected to the motor lead
with a watertight cable connector.
▪
Unless otherwise specified in the order documentation, KSB's
extension cables
are designed for:
–
Being laid freely exposed to air and in contact with surfaces
–
A voltage drop along the cable of
ᅀ
V
≦
3 %
For any other ways of laying the cable, e.g. in cable ducts, etc. observe the
information on the maximum current-carrying capacity as per the applicable
directives.
Extension cables connected by the operator
If the supplied extension cable is to be connected at the site, observe the following:
1.
Observe the installation instructions of the cable connector to be used.
2.
If the operator is responsible for connecting an extension cable, make sure the
extension cable is selected and dimensioned for a maximum voltage drop of
≦
3 %. The extension cable has to be approved for the applicable operating
conditions.
3.
In 4-core cables the earth conductor is part of the power cable and must also be
connected in the cable connector when connecting an extension cable.
4.
3-core motor leads do not include an earth conductor. A separate earth
conductor is connected on the outside of the motor. The earth conductor has to
be extended and connected separately.
