Electrical Safety Precautions
This section describes safety precautions for high voltage, thunderstorms, high leakage current, power cables, and fuses.
High Voltage
- Direct contact with a high-voltage power source or indirect contact through damp objects can be fatal.
- Misoperations on high-voltage facilities may result in fire, electric shock, or other accidents.
High Leakage Current
To protect personal and equipment safety, ground the equipment before powering it on.
If a high leakage current mark is labeled near the power connector of the equipment, you must connect the PGND terminal on the shell to the ground before connecting the equipment to an AC input power supply. This is to prevent the electric shock caused by leakage current of the equipment.
Power Cable
Never install or remove the equipment or power cables while the power is on. The electric arc or spark generated between a power cable and conductor may cause fire or eye damage.
- Before installing or removing power cables, you must power off the equipment.
- Before connecting a power cable, verify that the label on the power cable is correct.
Fuses
If the fuse on the equipment is blown, replace the fuse with a fuse of the same type and specifications to ensure safe operation of the equipment.
