Precautions of safety

On handling and installation work of the pump, assure safety by confirming the mass and
the shape of the pump referring to the appearance this instruction manual, drawing, the
catalogue, and other materials. There are dangers of dropping the pump and the injury of
worker.
Never execute the operation of the pump and the mounting work of parts in a lifted
position. That type of work is dangerous causing dropping of the pump and injury of
worker.
Do not damage, break, machine, forcefully bend, stretch, or twist the power cable, bind
the power cable into a bundle, or place a heavy load on the power cable. Those kinds of
handling cause fire and electric shock.
Execute correct wiring work by a qualified technician conforming to the appropriate legal
standards. Wrong wiring by non-qualified worker is illegal and may induce electric shock
and fire.
Do apply grounding wiring. The Green and Yellow stripe cord or the Green cord is the
grounding line. Never connect the Green and Yellow stripe cord to the power source
because there is a possibility of electric shock in case of trouble or electric leak.
To prevent electric shock, install an exclusive use ground fault breaker. The electric leak
may cause electric shock and fire.
If any dust is attached to a blade or blade-attaching face of the power source plug, fully
wipe the dust off with a dry-cloth. The attached dust may cause fire.
Warning
During operation of the pump, do not insert hand or foot in the suction opening of the
pump to avoid injury at the rotary section.
Never operate the pump in water in the presence of personnel.
If electric leak occurs, the personnel may suffer electric shock.
Disassembling, repairing, and modifying the pump shall be limited to a repair technician.
There is a possibility of injury caused by electric shock, ignition, abnormal functioning,
trouble, etc.
Before entering inspection and repair, cut OFF a power source at a main disconnect
device which is equipped with an operating handle which is lockable in OFF position.
There is a possibility of electric shock and of injury caused by sudden start of the pump in
automatic operation mode.
To stop operation for a certain period, cut OFF the power switch.
Deterioration of insulation may cause electric shock, electric leak, and fire.
The user of a standard model shall refer to the columns of standard specification. Do not
use the pump at outside the range of the specification in terms of handling liquid,
installing site, power source, etc. Operation at outside the specification may cause pump
trouble, injury, electric shock, electric leak, and fire.
Do not execute dry operation in air. That type of operation causes deterioration in
insulation to lead to electric shock and electric leak.
If the insulation resistance decreases to 1MΩ or less, immediately cut OFF the power
switch, and request the inspection and repair of the pump to the supplier or EBARA
There is a possibility of motor burn out, electric shock, and fire.
Confirm non-loosening at the wirings of motor, at the primary and secondary terminals of
control panel, and at the connection and wiring terminals of the power devices in the
control panel. Remove dust from these sections. Imperfect connection of wiring caused
by loosening and attached dust may cause ignition resulting in fire.
Do not attach parts other than EBARA's standard products, and do not modify EBARA's
products. There is a possibility of electric shock and ignition, or injury caused by abnormal
functioning, break, etc. Furthermore, there may fail in performing normal functioning.
