Precautions
• Wear an ESD-preventive wrist strap and make sure the wrist strap makes good skin contact.
• Before installing the power module, make sure the operating voltage provided by the external
power supply system is consistent with that marked on the power module, and the output voltage of
the power module is consistent with the powered device, preventing damage to the power module
and powered device.
• Do not touch any naked wire or terminal. Doing so may result in a personal injury.
• Never place the power module in wet locations and prevent fluid from leaking into the power
module.
• Do not often open the shell of the power module to prevent damage to the power module. If a
failure occurs on the internal wires or units, contact the technical stuff to troubleshoot the problem.
