CONFIRMATION
Don't pile packed pumps and don't lay each pump on its side in any case; otherwise the damage
may be caused to the pumps.
Keep space, 100mm or more at front and rear side, 50mm or more at lateral side, to secure
good ventilation for cooling. Bad ventilation can cause pump overheat which results in
unpredicted pump failure.
Do not place the device which could be heat source at the front of pump, and consider that air
ventilation temperature around pump is kept at 15 to 30 degrees C. High-temperature ventilation
heats up pump and causes pump failure.
For Input signals (Pin No. 1-9, 2-10, 3-11, 4-12), apply a voltage of 24V DC on the pump
controller side. Don't apply a voltage on the equipment side; otherwise the controller may go
wrong.
Pump stops in emergency off state if STOP/RESET switch on the controller is pressed during
pump operation with driving connector under direct power input. To restart the pump, turn
power off (wait until LED light goes off) then turn it back on.
Pump stops in emergency off state if STOP/RESET switch on the controller is pressed during
pump operation under remote control. To restart the pump, deactivate pump run command (pin
No. 1-9) then apply the command again or press STOP/RESET switch.
In the states that "LOCAL/REMOTE Selection Switch" in the I/O connector (CN2) is open –
means Pin No.3-11 is open circuit -, external signal mode is not available. In this case,
handling by operation-panel is required.
Pump stops if the controller is removed during operation.
Frequent power supply to the inverter may shorten the inverter life. Remote operation
described in 6.2.3 section P.37 is recommended if frequent RUN/STOP is necessary.
