Electrical Connections
WARNING
•
The pump must be earthed.
•
The pump must be connected to an external mains switch with a contact separation
gap of at least 3mm in each pole.
•
The pump must be connected to a 230V, 50Hz supply with a switched spur fused at
5A (10A on model BP130D).
•
Metal pipes must be earthed by the use of earthing clamps to BS 951 and 4mm
earthing wire. Where the earth continuity has been broken by flexible pipes the pump
discharge and suction pipe work should be connected with earthing clamps to BS 951
and 4mm earthing wire.
CAUTION
•
Complete all pipework before making electrical connections.
•
Do not allow any water to enter into the electric terminal box.
If in doubt - consult a qualified electrician.
Connect using the following colour code:
•
BROWN to terminal L (Live).
•
YELLOW/GREEN to terminal E (Earth). Ensure that the earth lead is at least as long
as the other two leads.
•
BLUE to terminal N (Neutral).
Insert the lead fully into the terminal connector and tighten the screw firmly. Ensure that the
connection is secure. Be sure to tighten the cable restraint.
Ensure compliance with the IEE Wiring Regulations (BS 7671).
In the interests of safety it is recommended that a residual current device (RCD) be
installed in the supply circuit.
WARNING
Do not operate pump without the terminal cover in place.
The pump switch should be left on at all times for normal operation of the system.
