3.5 Cooling water connections (all EH1200, EH2600 and EH4200
pumps only)
Note: Refer to Section 2.8 for the cooling water requirements.
Connect the cooling water supply and return lines. One connector is on the rear of the hydrokinetic drive/gearbox,
the other connector is on the underside of the gear cover. The supply and return lines can be connected to either of
the connectors; the direction of cooling water flow is not important.
Refer to Section 2.8 for the minimum cooling water flow rate required. If the danger of the condensation of gases in
the booster is not process critical, always connect the supply line to the gearbox cover first.
3.6 Electrical connections
3.6.1 Electrical supply configuration
Refer to the wiring instructions provided with the pump motor. Configure electrical connections according to the
manufacturer’s instructions.
3.6.2 Motor connections
The motor must be correctly configured and the electrical connections must be correct for the electrical supply.
If not, the motor can be damaged.
Ensure the electrical installation of the EH pump conforms with local and national safety
requirements. It must be connected to a suitably fused and protected electrical supply with a
suitable earth (ground) point.
Provide suitable strain relief on the electrical supply cable. If not, the cable (or wires in the cable)
may become disconnected from the pump and there may a risk of injury or death by electric shock.
Connect the electrical supply to the motor through a contactor which has a manual reset control.
Connect the electrical supply to the motor so that it is automatically switched off if the backing
pump stops. If not, the EH pump may overheat if it continues to operate when the backing pump
is stopped.
Ensure that the EH pump can be isolated and locked out from the electrical supply.
