Routine maintenance is critical to the normal operation of a device. Perform
routine maintenance regularly. Read all the precautions and product
documentation before performing maintenance.
Follow local laws and safety instructions to minimize the risk of personal
injury and damage to devices.
The "NOTICE", "CAUTION", "WARNING", and "DANGER" statements in this
document do not represent all the safety instructions. They are only
supplements to the safety instructions.
Personnel who plan to install, operate, or maintain devices need to receive a
thorough training, understand all necessary safety precautions, and be able to
correctly perform all operations.
Strictly follow the safety precautions and instructions of devices when
performing operations. Users are liable for any consequence caused by
violation of general safety operation requirements or safety standards for
device design, production, and use.
Most maintenance tasks need to be performed with power off. Do not
connect the power supply during maintenance. If you need to perform
maintenance tasks such as measuring the current, voltage, and temperature
when the device is operating, connect the power supply only after you have
connected all cables. Disconnect the power supply when you finish

maintenance.

Protective measures, such as wearing insulation gloves or shoes, must be
taken during electrical maintenance.
