5 Operation
5.1 Operation precautions
Before starting work, make sure that the safety instructions in the chapter
Introduction and
Safety
on page 3 have been read and understood.
DANGER:
Never operate a pump without a properly installed coupling guard. Personal injury will occur
if you run the pump without a coupling guard.
WARNING:
• Install, earth (ground), and wire the equipment according to the local and National
Electrical Code Requirements.
• Install an all leg disconnect switch near pump.
• Disconnect and lock out electrical power before installing or servicing the unit.
• Electrical supply must be in accordance with the specifications given on the pump’s
nameplate.
• Motors equipped with automatic thermal protectors open the motor’s electrical circuit
when an overload exists. This can cause the pump to start unexpectedly and without
warning.
Use only stranded copper wire to motor and ground. Wire size MUST limit the maximum
voltage drop to 10% of the motor nameplate voltage, at the motor terminals. Excessive
voltage drop will affect performance and void motor warranty. The ground wire must be at
least as large as the wires to the motor. Wires should be color coded for ease of
maintenance.
Three phase motors require all leg protection with properly sized magnetic starters and
thermal overloads.
Electrical Hazard:
Make sure that you have grounded (earthed) the pump, the drive unit, and the controls
before connecting the electrical power.
