PRODUCT INFORMATION

Powering the Motor

Powering the Motor
Risk of severe injury or death by electrical shock.
• To reduce risk of electrical shock, disconnect power and lockout-tagout before working on or around
the system. More than one disconnect switch may be required to de-energize the equipment before
servicing.
• If the power disconnect is out of sight, lock it in the open position and tag it to prevent unexpected
application of power.
• Make sure that the supply voltages and frequencies are suited to the characteristics of the submers-
ible rewindable electric motor.
Observe the instructions on the motor type plate and dimension the electrical system accordingly. The con-
nection examples in this chapter concern the actual motor and do not serve as recommendation for the
upstream control elements.
Ensure that all steps in the previous section have been properly followed.
Power Supplied by a Generator
Discuss power requirements of the site with the generator manufacturer.
The voltage tolerance, 50Hz: -10% to +6%/ 60Hz: ± 10%, (on the motor terminals) and the deviation of a
motor current from the mean value of all three currents must not be more than 5%.
Generator selected on the basis of the motor start behavior (i.e. starting current with a power factor of 0.5).
Generator provides sufficient continuous power without fail.
Starting voltage at least 55% of the nominal voltage.
You must follow the following on/off sequences unconditionally:
• ON: first switch on the generator and then the motor.
• OFF: first switch off the motor and then the generator.
Fusing and Motor Protection
Provide an external mains switch (1) enabling the voltage to be removed
from the system.
Provide fuses (2) for every single phase on site.
Provide a motor starting and protection switch (3)(see connection alterna-
tives).
Provide an emergency stop system, if required for your specific application.
Ground the motor (4) (exterior grounding possible with all motors).
Surge Voltage Protection
IEC 60099 requires installation of an overload/surge protector (5) within the power supply.
