High-voltage precautions
A high-voltage power supply provides power for the device. Direct or indirect contact (through damp objects) with a high-voltage power supply (including the main power in a building) can result in fatal danger.
When installing the AC power supply, follow standard safety regulations. Personnel who install the AC power supply must be qualified to perform high voltage and AC operations.
Do not wear conductive objects such as a watch, chain, bracelet, or ring during the operation.
Switch off the power supply immediately if you find water in the cabinet or if the rack is damp.
Make sure that the device is kept away from water when being operated in a damp environment.
Improper operation on a high-voltage power supply may result in fire and electric shock. To connect and route the AC cables through a certain area, you must follow standard rules and regulations. Personnel must have an up-to-date certificate for operating high voltage and AC power devices.
You must use insulated tools when operating on high voltage and AC power.
Do not install or remove a power cord or Power Distribution Unit (PDU) cord when the power is turned on. Minimal contact between the core of the cord and a conductor can generate an electric arc or spark, to cause a fire or injury.
Wrap bare wires of the power cable with insulated tape before connecting the cable to the power distribution cabinet.
Before installing or removing the power cord or PDU cord, turn off the power.
Before connecting the power cord or PDU cord, make sure that the cord and label conform to the requirements for the installation.
Do not perform operations on high voltage, power supplies, and connections, or other conductive materials during thunder storms.
Be sure that all devices are properly grounded to prevent damage or injury during storms.
