Installing and removing a power
module
Safety precautions
To avoid possible bodily injury and power module and device damage,
follow these safety precautions:
•
When you install and remove a power module, always wear an
ESD-preventive wrist strap and make sure it makes good skin
contact.
•
Before you install the power module, make sure the voltage of the
power supply system is the same as the rated voltage of the power
module, and the output voltage of the power module is the same as
the voltage required by the device.
•
Do not touch any cables or terminals of the power module.
•
Do not place the power module in a wet area, and prevent liquid
from flowing into the power module.
•
To avoid power module damage, do not open the power module.
When the internal circuits or components of the power module fail,
contact the maintainer for examining and repairing.
