Power Supply
(10)When attaching the main power cord to the pump,
please use the power cord which meets the rated
voltage and current, pursuant to the provision.
4-Core-cable(Size of the wire lead: 1.0m
㎡
or larger,
300V or more, 10A or more,
100
℃
or higher, one
earth cable included)
Ensure that one of the core wires is used as an earth
wire. Firmly attach the 6 - 12mm diameter Cable gland
compatible cable fitted with the appropriate terminals
(M3 terminal block screws) to a terminal block.
Tighten the cap of the cable gland by max 2.5N
･
m.
Failure to follow these requirements may result in
electric shock.
Wiring and ground construction should be done subject
to your local law and the safety requirements.
The wire with insulation having an outer surface that is
green with or without yellow stripes is the grounding
wire.
(11) Switch off the main power supply, before disconnecting the power wire from the pump.
Failure to do so may result in electric shock.
(12) Touching the power cord with wet hands may result in electric shock.
(13) Touching electrical wiring etc while inserting the power cord may result in electric shock.
(14)The electric motor fitted to this pump incorporates a thermal protector; however it is not
guaranteed to be open when it eventually fails at some time. For safety reasons therefore, it
is necessary to fit an overload (over current), protection device and an earth leakage
breaker.
Operation
(15) This pump is not designed to be explosion-proof. When using the pump, ensure that there
are no inflammable materials such as solvents, or explosive gases, in the vicinity. Use under
such conditions may result in injury or fire.
(16) Inserting fingers or objects into the motor inlet may result in electric shock, injury, or fire.
(17) Operating the pump with the discharge outlet blocked, or with a device which prevents
passage of gas to the discharge outlet, may result in rupture of the pump. The internal
pressure of the pump rises and the pump body may rupture and the motor become
overloaded.
This pump is not designed to be pressure-resistant. The internal pressure of the pump is
limited to 0.03 MPa (gauge pressure).
Maintenance and Repair
(18) The pump should be dismantled or repaired only by a repair technician trained by the
manufacturer.
(19) To prevent ingestion of microscopic particles resulting from wear of components, use a dust
mask and gloves during repair work.
