naonal safety requirements. The pump must be connected to a suitably fused and
protected electrical supply with a suitable earth point. For recommended cord sets
refer to Electrical cables on page 22.
Note:
To prevent automac restart of the pump-motor if the electrical supply is restored aer
an electrical supply failure, connect the pump to the electrical supply through suitable
control equipment which must be reset manually aer an electrical supply failure.

Ensure that the on/o switch on the motor (Figure: Motor voltage conguraon:
single-phase pumps, item 4) is in the ‘o’ posion.
2.
Insert the moulded IEC connector at the end of the cable into the electrical inlet-
connector on the motor (Figure: Motor voltage conguraon: single-phase pumps,
item 2).
3. Connect the plug (if ed) at the other end of the cable to the electrical supply. If a
plug is not ed, connect the wires in the cable to the correct terminals of the
electrical supply.
4.6.3 Check the direcon of rotaon
