Safety Precautions
The following precautions are for checking products upon delivery, installation, wiring,
operation, maintenance and inspections.
Checking Products upon Delivery
Installation
Wiring
•Always use the servomotor and servo amplifier in one of the specified combinations.
Not doing so may cause fire or malfunction.
•Never use the products in an environment subject to water, corrosive gases, inflammable gases, or
combustibles.
Doing so may result in electric shock or fire.
•Connect the ground terminal to a class 3 ground (100Ωor less).
Improper grounding may result in electric shock or fire.
• Required for 7.5kW amplifiers:
Use of Yaskawa kit Number JZSP-CKT75 for wiring the power input and output terminals, or equivalent
UL listed closed-loop ring terminals designed to accept 4 AWG wires.
• Required for 200V, 11kW and 15kW amplifiers:
Use of Yaskawa kit number JZSP-CKT75 for wiring the power input and output terminals of the SGDH-
1AAE, and JZSP-CKT1E for the SGDH-1EAE, or equivalent UL listed closed-loop ring terminal to accept 4
AWG and 2 AWG wires respectively.
• Required for 400V, 6.0kW and 7.5kW amplifiers:
Use of Yaskawa kit Number JZSP-CKT75DE for wiring the power input and output terminals, or
equivalent UL listed closed-loop ring terminals designed to accept 8 AWG wires.
• Required for 400V, 11kW amplifiers:
Use of Yaskawa kit Number JZSP-CKT1ADE for wiring the power input and output terminals, or
equivalent UL listed closed-loop ring terminals designed to accept 8 AWG wires.
• Required for 400V, 15kW amplifiers:
Use of Yaskawa kit Number JZSP-CKT1EDE for wiring the power input and output terminals, or
equivalent UL listed closed-loop ring terminals designed to accept 6 AWG wires.

Operation
•Do not connect a three-phase power supply to the U, V, or W output terminals.
Doing so may result in injury or fire.
•Securely fasten the power supply terminal screws and motor output terminal screws.
Not doing so may result in fire.
•Never touch any rotating motor parts while the motor is running.
Doing so may result in injury.
•Conduct trial operation on the servomotor alone with the motor shaft disconnected from machine to
avoid any unexpected accidents.
Not doing so may result in injury.
•Before starting operation with a machine connected, change the settings to match the parameters of
the machine.
Starting operation without matching the proper settings may cause the machine to run out of control or
malfunction.
•Before starting operation with a machine connected, make sure that an emergency stop can be applied
at any time.
Not doing so may result in injury.
•Do not touch the heat sinks during operation.
Not doing so may result in burns due to high temperatures.
