Installation Electrical
1. Electrical connection
a. Preparation
i. Ensure that the voltage and frequency of the supply match the requirements on the data
plate.
ii. Ensure that all circuit breakers and similar equipment are rated correctly, and set to the
appropriate level where applicable.
iii. Ensure that all cables and wires are of a sufficient specification for the required current
and voltage, and comply with all relevant regulations.
iv. Ensure that the pump cable sheath is completely undamaged. Any cuts or holes which
penetrate the outer sheath or further are not permitted, and the pump should not be used if
any such fault is present. Water can travel down the inside of the outer sheath and into the
motor.
v. If the pump will be running intermittently, ensure that the max start/stops of the pump are
complied with through the appropriate means.
vi. The cable gland on the pump is resin-filled to ensure weathertightness. If the cable is
strained in any direction this may be compromised and therefore the pump should be
returned to the dealer / manufacturer for the cable to be re-set in resin.
b. Connection
i. Ensure that control panel entry holes are suitably protected to prevent cable damage and
isolate accidental cable strain to outside the panel. In most cases this will be an IP rated cable
gland.
ii. Use cable crimps or ferrules where possible to ensure that all strands of each core are
used, remain undamaged, and are protected.
iii. Earth should always be connected to the earth terminal in the panel.
iv. With three phase pumps the three live connections are usually numbered 1 to 3, and most
commonly connected as follows for the correct phase rotation:
1. Normally Brown / Red
2. Normally Black
3. Normally Grey / Gray / Blue
