3.1 WARNINGS AND CAUTIONS RELATING TO MOUNTING
3.1.1 WARNING
- Check the specification code of the amplifier.
Check that the delivered amplifier is as originally ordered.
- Mount a ground fault interrupter.
To guard against fire and electric shock, fit the factory power
supply or machine with a ground fault interrupter (designed for
use with an inverter).
- Securely ground the amplifier.
Securely connect the ground terminal and metal frame of the
amplifier and motor to a common ground plate of the power
magnetics cabinet.
- Be aware of the weight of the amplifier and other
components.
Control motor amplifiers and AC reactors are heavy. When
transporting them or mounting them in the cabinet, therefore, be
careful not to injured yourself or damage the equipment. Be
particularly carefull not to jam your fingers between the cabinet
and amplifier.
- Never ground or short-circuit either the power supply lines or
power lines.
Protect the lines from any stress such as bending. Handle the ends
appropriately.
- Ensure that the power supply lines, power lines, and signal
lines are securely connected.
A loose screw, loose connection, or the like will cause a motor
malfunction or overheating, or a ground fault.
- Insulate all exposed parts that are charged.
- Never touch the regenerative discharge resistor or radiator
directly.
The surface of the radiator and regenerative discharge unit
become extremely hot. Never touch them directly. An
appropriate structure should also be considered.
- Close the amplifier cover after completing the wiring.
Leaving the cover open presents a danger of electric shock.
- Do not disassemble the amplifier.
