230 V and Figure: Three-phase electrical connections: 380–460 V , item 1) to suit
the local electrical supply:
▪ For 200-230 V electrical supplies, the links must be configured as shown in
Figure: Three-phase electrical connections: 200–230 V .
▪ For 380-460 V electrical supplies, the links must be configured as shown in
Figure: Three-phase electrical connections: 380–460 V .
4.7.2 Connect the pump to the local electrical supply
WARNING:
Ensure that the electrical installation of the RV pump conforms with local and
national safety requirements. It must be connected to a suitably fused and protected
electrical supply and a suitable earth (ground) point.
Note:
To prevent automatic restart of the pump-motor if the electrical supply is restored after
an electrical supply failure, connect the pump to the electrical supply through suitable
control equipment which must be reset manually after an electrical supply failure.
We recommend that the electrical supply is connected to the motor through a starter or
circuit breaker which has thermal over-current protection which can be adjusted to suit
the full load current ratings shown in Table: Electrical data (three-phase pumps with Part
Numbers ending in -905) . The fuse ratings in Table: Electrical data (three-phase pumps
with Part Numbers ending in -905) are provided for guidance only. The supplier of the
thermal over-current protection device may specify different values to ensure correct
operation of the fuse and the over-current protection device. Ensure that the fuse used
is suitable for the starting currents given in Table: Electrical data (three-phase pumps
with Part Numbers ending in -905) .
1. Remove the cover from the motor terminal box.
2. Remove the cable-gland from the inside of the terminal box and fit the cable-gland
to the cable lead through hole in the side of the terminal box. Using a tool this
should be tightened to a torque of 3.75 Nm.
3. Pass the electrical supply cable through the cable-gland. The diameter of the
electrical supply cable should be in the range 7 to 11 mm.
4. Use insulated crimped connectors to connect the wires in the cable to the
terminals U1, V1 and W1 and Earth (ground) in the terminal-box as shown in
Figure: Three-phase electrical connections: 200–230 V and Figure: Three-phase
electrical connections: 380–460 V . The earth (ground) terminal connection must be
tightened to a torque of 2.13 to 2.87 Nm.
5. Tighten the dome-shaped nut on the cable-gland until the outer sheath of the
cable is firmly gripped. Using a tool this should be tightened to a torque of 2.5 Nm,
do not overtighten.
6. Ensure that the cover gasket is correctly positioned, then refit the cover to the
terminal-box and secure with the screws.
