3.7.1 Connection of electric motors
• Prior to connecting the motor, always consult the electricity company’s regulations
(European standard EN60204-1.)
• Employ a thermal motor protection switch.
• Adjust the motor protection switch to the nominal current absorbed by the motor.
• So as to be able to work safely on a pump set one must install a circuit breaker as
close as possible to the machine. It also is advisable to place an earth leakage switch.
• Leave the connecting of electric motors to qualified personnel.
• Take the necessary measures to prevent damage to electrical connections and wiring.
• Electrical equipment, terminals and components of control systems may still carry live
current when at rest.
• Contact with these may be fatal, result in serious injury or cause irreparable material
damage.
• The switching equipment must comply with current regulations, as stipulated by
EN60204-1.
• For single-phase alternating current, use motors with a sufficient high starting torque.
• Always provide proper earthing.
• Check motor specifications for start-stop frequency.
