Electrical connection

Before commissioning, an expert should check that one of the necessary electrical protective devices
is available. Earthing, neutral, earth leakage circuit breakers, etc. must comply with the regulations
of the local electricity supply authority and a qualified person should check that these are in perfect
order.
ATTENTION! The power supply system on site must comply with local regulations with regard
to cross-sectional area and maximum voltage drop. The voltage stated on the
nameplate of the pump must correspond to that of the mains.
Suitably rated means of disconnection shall be incorporated in the fixed wiring by the installer for all pumps in
accordance with applicable local National codes.
The power supply cable must be protected by an adequately dimensioned slow-blow fuse corresponding to the
rated power of the pump.
The incoming power supply as well as the connection of the pump itself to the terminals on the control
panel must comply with the circuit diagram of the control panel as well as the motor connection
diagrams and must be carried out by a qualified person.
All relevant safety regulations as well as general good technical practice must be complied with.
Submersible pumps used outdoors must be fitted with a power cable of at least 10 metre length. Other
regulations may apply in different countries.
In all installations, the power supply to the pump must be via a residual current device (e.g. RCD, ELCB, RCBO
etc.) with a rated residual operating current in accordance with local regulations. For installations not having a
fixed residual current device the pump must be plugged into the power supply through a portable version of the
device.
All three phase pumps must be installed with motor starting and overload protective devices in the fixed wiring
by the installer. Such motor control and protective devices must comply with the requirements of IEC standard
60947-4-1. They must be rated for the motor that they control, and wired and set/adjusted according to the
instructions provided by the manufacturer. In addition, the overload protective device that is responsive to the
motor current shall be set / adjusted to 125% of the marked rated current.
Risk of electrical shock. Do not remove cord and strain relief and do not connect conduit to pump.
NOTE Please consult your electrician.
The following components should be incorporated in the fixed wiring for all single phase pumps:
• Motor starting and/or running capacitor that complies with the requirements of IEC 60252-1 and rated as
specified in the installation instruction. The capacitor shall be class S2 or S3.
• Motor contactor that complies with the requirements of IEC Standard 60947-4-1 and rated for the motor that it
controls.
