[To prevent electric shock, note the following]
[To prevent fire, note the following]
WARNING
●
Before wiring, turn off the power and wait for 20 minutes or more until the charge lamp turns off. Then,
confirm that the voltage between L+ and L- is safe with a voltage tester or others. Otherwise, an
electric shock may occur. In addition, when confirming whether the charge lamp is off or not, always
confirm it from the front of the converter unit.
●
Ground the converter unit, drive unit, and servo motor securely.
●
Any person who is involved in wiring and inspection should be fully competent to do the work.
●
Do not attempt to wire the converter unit, drive unit, and servo motor until they have been installed.
Otherwise, it may cause an electric shock.
●
Do not operate the switches with wet hands. Otherwise, it may cause an electric shock.
●
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause an electric
shock.
●
During power-on or operation, do not open the front cover of the converter unit and the drive unit.
Otherwise, it may cause an electric shock.
●
Do not operate the converter unit and the drive unit with the front cover removed. High-voltage
terminals and charging area are exposed and you may get an electric shock.
●
Except for wiring or periodic inspection, do not remove the front cover of the converter unit and the
drive unit even if the power is off. The converter unit and the drive unit are charged, and you may get
an electric shock.
●
To prevent an electric shock, be sure to connect the protective earth (PE) terminal (marked ) of the
converter unit and the drive unit to the protective earth (PE) of the cabinet.
●
To avoid an electric shock, insulate the connections of the power supply terminals.
CAUTION
●
Install the converter unit, the drive unit, the servo motor, and the regenerative resistor on
incombustible material. Installing them directly or close to combustibles will lead to smoke or a fire.
●
Be sure to connect a magnetic contactor between the power supply and the main circuit power supply
(L1/L2/L3) of the converter unit, in order to configure a circuit that shuts off the power supply by the
magnetic contactor. If the magnetic contactor is not connected, a continuous flow of a large current
may cause smoke or a fire when the converter unit or the drive unit malfunctions.
●
Be sure to connect a magnetic contactor for each converter unit between the power supply and the
power supply (L1/L2/L3) of the converter unit, in order to configure a circuit that shuts off the power
supply by the magnetic contactor. If a molded-case circuit breaker or fuse is not connected, a
continuous flow of a large current may cause smoke or a fire when the converter unit malfunctions.
●
When using the regenerative resistor, shut the power off with an alarm signal. Otherwise, a
regenerative transistor malfunction or the like may overheat the regenerative resistor, causing smoke
or a fire.
● Provide adequate protection to prevent screws and other conductive matter, oil and other combustible
matter from entering the converter unit, the drive unit, and the servo motor.
