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 and is well grounded.
•
Before you install the power module, make sure the voltage of the
power source is the same as the rated voltage of the power module,
and the output voltage of the power module is as required.
•
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.
Tools
Prepare an ESD-preventive wrist strap and a flat-blade screwdriver
yourself.
