Electrical connection
1.
Connect the connecting cable with power switched off and
secure against reconnection.
2.
Lay the connecting cable such that it doesn't come into
contact with the pump, the pump housing or the piping.
3.
Check whether the voltage and amperage in the mains match
the specifications on the type plate of the pump.
4.
Open the terminal box.
5.
Lay the cable such that no condensation or spray water can
run into the cable screws (Fig. A).
6.
Connect grounding cable.

Caution: Damage due to overheating!
For insulated piping systems, only the pump volute may be
insulated, not the lantern and the motor. These could be
damaged by heat build-up.
Danger: life threatening due to electrical shock!
Touching live parts can be fatal. Work on the electrical connec-
tion may only be performed by a trained electrician. Prior to
connecting, ensure that the connecting line is voltage-free.
Warning: Danger due to a damaged cable!
For pumps that pump hot liquids or that are used in proximity to
hot surfaces with temperatures above 194 °F [90 °C], a heat-
resistant cable must be used.
Note:
For the correct cable size, refer to local wiring
restrictions.
Caution: Damage due to incorrect voltage!
Never operate the pump with incorrect voltage. This could
damage the motor.
