WARNING: LIGHTNING STRIKE
Risk of re and injury from lightning strike. The operator is responsible for assessing the
hazard potenal when used outside of buildings.
7.6.1 Wiring the motor
All variants of EDS pump are supplied with a three-phase 5.5 or 7.5 kW pump motor.
Wire the motor in accordance with the instrucons supplied with the motors.
Ensure that the electrical installaon of the EDS pump conforms to your local and naonal
safety requirements. It must be connected to a suitably rated fused and protected electrical
supply and a suitable earth (ground) point.
Provide suitable strain relief on the electrical supply cables. If you do not, the cables (or
wires in the cables) may become disconnected and there may be a risk of injury or death by
electric shock.
We recommend that you connect the electrical supply to the pump motor through a suitable
current monitor, and that you congure the high current seng on the current monitor to
switch o the pump motor at a suitable overload current.
Connect the electrical supply to the pump motor through a contactor which has a manual
reset control. The contactor must be installed such that manual reset is required aer a
power failure. The contactor must incorporate a motor circuit-breaker which meets the full
load current rangs of the pump motor.
You must be able to isolate and lock out the electrical supply to the EDS pump motor.
The EDS pump can be operated direct-on-line or via a frequency converter. Selecon and
installaon of a frequency inverter is the responsibility of the user. Ensure that the motor
operaon and cercaon is not adversely aected by the use of a frequency converter. The
min and max motor speeds given in the technical data must be followed.
