Edwards RV3 Instruction Manual

230 V and Figure: Three-phase electrical connecons: 380–460 V, item 1) to suit
the local electrical supply:
▪ For 200-230 V electrical supplies, the links must be congured as shown in
Figure: Three-phase electrical connecons: 200–230 V.
▪ For 380-460 V electrical supplies, the links must be congured as shown in
Figure: Three-phase electrical connecons: 380–460 V.
4.7.2 Connect the pump to the local electrical supply
WARNING:
Ensure that the electrical installaon of the RV pump conforms with local and
naonal safety requirements. It must be connected to a suitably fused and protected
electrical supply and a suitable earth (ground) point.
Note:
To prevent automac restart of the pump-motor if the electrical supply is restored aer
an electrical supply failure, connect the pump to the electrical supply through suitable
control equipment which must be reset manually aer 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 protecon which can be adjusted to suit
the full load current rangs shown in Table: Electrical data (three-phase pumps with Part
Numbers ending in -905). The fuse rangs 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 protecon device may specify dierent values to ensure correct
operaon of the fuse and the over-current protecon device. Ensure that the fuse used
is suitable for the starng 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 t the cable-gland
to the cable lead through hole in the side of the terminal box. Using a tool this
should be ghtened 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 connecons: 200–230 V and Figure: Three-phase
electrical connecons: 380–460 V. The earth (ground) terminal connecon must be
ghtened to a torque of 2.13 to 2.87 Nm.
5.
Tighten the dome-shaped nut on the cable-gland unl the outer sheath of the
cable is rmly gripped. Using a tool this should be ghtened to a torque of 2.5 Nm,
do not overghten.
6.
Ensure that the cover gasket is correctly posioned, then ret the cover to the
terminal-box and secure with the screws.
