● No operation under power connected state. Otherwise, there is danger of electric shock.
● Before operation, please cut all related equipments power, ensure that the main circuit DC current has dropped to
safe range. And please operate after 5 mins.
● No operation while cover/panel is dismantled. Otherwise, there is danger of electric shock.
● Do not dismantle the cover or PCB under power connected state. Otherwise, there is danger of electric shock.
● Only professional person can install, debug or maintain the peripheral equipments and options. Otherwise, there is
danger.
● Do not ware loose clothes when install, debug, maintain. Rated protective tools and safeguard should be adopted.
● Do not change wire, dismantle jumping wire, optional card, or change cooling fan while the drive is running.
Otherwise, there is danger of electric shock.
● Tighten screw according to named torque. If main circuit wire connection is loose, there is danger of overheat fire.
● Earth of the peripheral equipments and options must be reliable to prevent human body injury.
● While operation, please follow the ESD regulations. Otherwise, the drive maybe damaged.
● Do not cut the power supply while the drive is outputting voltage. Otherwise, the drive maybe damaged.
