Electrical wiring
WARNING !
• This pump cannot be used in explosion-proof regions or in explosive or combustible atmospheres.
• Take steps to ensure that the power will not be turned on during the course of work. Hang a sign on the
power switch indicating that work is in progress.
• Do not operate the pump with wet hands. Doing so may result in electric shocks.
• Securely ground the protective earth terminal, and be absolutely sure to install a ground fault circuit
interrupter. Otherwise, you may receive electric shocks.
• Do not attempt to disassemble the pump body or the circuit parts.
!
CAUTION
• The wiring must be done by a qualified electrician or somebody with electrical knowledge.
• Connect the wires after checking the supply voltage. Do not connect the wires to a power supply that is
not within the rated voltage range.
Example of wiring
● When operating the pump in tandem
with an irrigation pump, etc.
● When running the pump on its own
IMPORTANT
• Be absolutely sure to use a commercial power source (the power
supplied by an electric power company) for supplying the power.
<Power sources that cannot be used>
Power sources in which an AC power regulator is installed
Power sources on the output side of an inverter
• Since a high voltage is generated when the power is cut off or in
other such circumstances and this may result in trouble, do not
take the power from the same terminals as the induction motor of
an irrigation pump, etc.
NOTE
• When installing an overcurrent protection device for this pump, always install a circuit protector (CP) in
consideration of the operating time and the breaking current characteristics.
• The circuit protector (CP) shown as the recommended protection device can also be used as the
powerswitch, thus simplifying the wiring connections.
• A thermal relay (TH) is used to protect against heat generation due to motor overload, which makes
it suitable for motor pumps or other equipment that are operated continuously, but it is unsuitable for
this solenoid-driven pump, which is operated non-continuously. In this case, the pump may not operate
properly.
