3.1.2 Electrical Safety
High Voltage
The high voltage power supply provides power for the device operation. Direct or indirect
contact (through damp objects) with high voltage and AC mains supply may result in serious
injuries.
During the installation of the AC power supply facility, follow the local safety
regulations. The personnel who install the AC facility must be qualified to perform high
voltage and AC operations.
Do not wear conductive articles, such as watches, hand chains, bracelets, and rings
during the operation.
When water is found in the rack or the rack is damp, switch off the power supply
immediately.
When the operation is performed in a damp environment, make sure that the device is
dry.
Non-standard and improper high voltage operations may result in fire and electric shock.
Therefore, you must abide by the local rules and regulations when bridging and wiring AC
cables. Only qualified personnel are allowed to perform high voltage and AC operations.
Before powering on a device, ground the device. Otherwise, personal injury or device damage
may be caused by high leakage current.
Tools
Dedicated tools must be used during high voltage and AC operations. Avoid using ordinary
tools.
TP48600B-N16A3
User Manual 3 Safety

High Electrical Leakage
Ground the device before powering it on. Otherwise, personal injury or device damage may
be caused by high leakage current.
If a "high electrical leakage" tag is present on the power terminal of the device, you must
ground the device before powering it on.
3.1.3 Inflammable Environment
Operating the electrical device in an inflammable environment can be fatal.
Do not place the device in an environment that has inflammable and explosive air or gas. Do
not perform any operation in this environment.
3.1.4 Battery
Storage Battery
Before operating storage batteries, carefully read the safety precautions for battery handling
and connection.
Improper handling of storage batteries causes hazards.
When operating storage batteries, avoid short circuit and overflow or leakage of the
electrolyte. Electrolyte overflow may damage the device. It will corrode metal parts and
circuit boards, and ultimately damage the device and cause short circuit of circuit boards.
Basic Precautions
Before installing and maintaining the battery, note the following:
Do not wear metal articles such as wristwatch, hand chain, bracelet, and ring.
Use special insulation tools.
TP48600B-N16A3
User Manual 3 Safety

Take care to protect your eyes when operating the device.
Wear rubber gloves and a protective coat in case of electrolyte overflow.
When handling a storage battery, ensure that its electrodes are upward. Leaning or
reversing the storage battery is prohibited.
Short Circuit
Battery short circuit may cause human injuries. Although the voltage of ordinary batteries is
low, the instantaneous high current caused by the short circuit releases a great deal of energy.
There is danger of explosion if the battery is incorrectly replaced. Therefore, replace the
battery only with the same or equivalent type recommended by the manufacturer.
Keep away metal objects, which may cause battery short circuit, from batteries. If metal
objects must be used, first disconnect the batteries in use before performing any other
operations.
Hazardous Gas
Do not use unsealed lead acid storage batteries. Lead acid storage batteries must be placed
horizontally and stably to prevent the batteries from releasing flammable gas, which may
cause fire or erode the device.
Lead acid storage batteries in use emit flammable gas. Therefore, ventilation and
fireproofing measures must be taken at the sites where lead acid storage batteries are used.
Battery Temperature
If a battery overheats, the battery may be deformed or damaged, and the electrolyte may
overflow.
When the temperature of the battery is higher than 60℃, check the battery for electrolyte
overflow. If the electrolyte overflows, absorb and counteract the electrolyte immediately.

3.2.1 Electricity Safety
High Electrical Leakage
If the "high electrical leakage" tag is present on the power terminal of the device, you must
ground the device before powering it on.
3.2.2 Electrostatic Discharge
The static electricity generated by human bodies may damage the electrostatic-sensitive
components on boards, for example, the large-scale integrated (LSI) circuits.
Human body movement, friction between human bodies and clothes, friction between shoes
and floors, or handling of plastic articles causes static electromagnetic fields on human bodies.
These static electromagnetic fields cannot be eliminated until the static is discharged.
To prevent electrostatic-sensitive components from being damaged by the static on human
bodies, you must wear a well-grounded electrostatic discharge (ESD) wrist strap when
touching the device or handling boards or application-specific integrated circuits (ASICs).
Figure 3-2 shows how to wear an ESD wrist strap.
