Wiring
◆
Do not allow non-professionals to perform product installation, wiring, maintenance, inspec-
tion or parts replacement.
◆
Never perform wiring at power-on. Failure to comply may result in electric shock.
◆
Cut off all power supplies before wiring. Wait at least 10 minutes after power-off so that re-
sidual voltage can discharge safely. Wait at least 10 minutes after power-off so that residual
voltage can discharge safely.
◆
Make sure that the equipment is reliably grounded. Failure to comply may result in electric
shock.
◆
Follow the proper electrostatic discharge (ESD) procedures, and wear an anti-static wrist
strap to perform wiring. Failure to comply may result in damage to the equipment or the
internal circuit the product.
◆
Never connect the power cable with the product output terminals (U, V, W.). Failure to com-
ply may result in equipment damage or even fire.
◆
When connecting driving equipment with the motor, make sure the phase sequence of the
drive and motor are consistent to prevent motor reverse rotation.
◆
The cable used in wiring must conform to the wire diameter and shielding requirements,
the shielding layer of the shielded cable must be reliably grounded at one end.
◆
After wiring, make sure there are no fallen screws or exposed wire inside the cabinet or
product.
Power-on
◆
Before power-on, make sure that the equipment or products are intact, all wiring are safely
connected, and the motor device allows a restart.
◆
Before power-on, check if the power supply meets the equipment requirements, avoid
equipment damage or fire.
◆
At power-on, equipment or product may start running abruptly, keep away from mechanical
device.
◆
After power-on, never open the cabinet door or the protective shell to avoid electric shock.
◆
Never touch any terminals at power-on to avoid electric shock.
◆
Never dismantle the equipment or remove any parts from the equipment at power-on to
avoid electric shock.
Operation
◆
Never touch any terminals during operation. Failure to comply may result in electric shock.
◆
Never dismantle the equipment or remove any parts from the equipment during operation.
Failure to comply may result in electric shock.
◆
Never touch the equipment shell, fan or resistor for temperature detection. Failure to com-
ply may result in burn!
◆
Do not allow non-professional technicians to detect signals during operation. Failure to
comply may result in equipment damage even personal injuries.
