Personal Safety
Before any operations, take off conductive objects such as jewelry and watches to avoid
electric shocks or burns.
For personal safety, wear insulation gloves and safety shoes during operation and
maintenance (O&M).
Use tools in correct methods to avoid hurting people or damaging devices.
In the case of fire, immediately leave the building or the equipment room, and turn on
the fire alarm bell or make an emergency call. Do not enter a building that is on fire.
When the operation is performed in a damp environment, ensure that the device is dry.
When water is found in the rack or the rack is damp, switch off the power supply
immediately.
Equipment Safety
The device must be secured on the floor or to other immovable objects such as walls and
mounting supports before operation.
Tighten the screws by using a tool when installing components.
After the installation, remove packing materials from the equipment area.
High Voltage
The high voltage power supply provides power for the device operation. Direct or indirect
contact (especially with a damp object) with the high voltage power supply may result in
fatal injury.
Non-standard and improper high voltage operations may result in fire and electric shocks.
Personnel who install AC facilities must be qualified to perform high voltage and AC
operations.
You must abide by the local rules and regulations when bridging and routing AC cables.
Follow the local laws and regulations when installing AC power facilities.
Use dedicated tools when performing high voltage and AC operations.
Put on insulation gloves before powering on or off cabinets.
Power Cables
Do not connect or disconnect power cables under power. Transient contact between the core
wire of the power cable and the conductor will generate electric arcs or sparks, which may
cause fire or personal injury.
Before connecting or disconnecting a power cable, turn off the upstream power switch,
and use a multimeter to check that the AC and DC voltages of the input port are zero.
Before connecting a power cable, check that the label on the power cable is correct.
