1.3 Electrical Safety
Grounding
AC and DC Power
ESD
For the equipment that needs to be grounded, install the ground cable first when installing the
equipment and remove the ground cable last when removing the equipment.
Do not damage the ground conductor.
Do not operate the equipment in the absence of a properly installed ground conductor.
Ensure that the equipment is connected permanently to the protective ground. Before operating the
equipment, check its electrical connection to ensure that it is securely grounded.
DANGER
Do not connect or disconnect power cables with the power on. Transient contact between the
core of the power cable and the conductor will generate electric arcs or sparks, which may
cause fire or personal injury.
Before installing or removing a power cable, turn off the power switch.
Before connecting a power cable, check that the label on the power cable is correct.
If the equipment has multiple inputs, disconnect all the inputs before working with the
equipment.
A damaged power cable must be replaced by the manufacturer, service agent, or professionals
to avoid risks.
High voltage operations and installation of AC-powered facilities must be performed by qualified
personnel.
Wear ESD gloves or a well-grounded ESD wrist strap when touching the device or handling boards
or application-specific integrated circuits (ASICs).
When holding a board, hold its edge without touching any components. Do not touch the components
with your bare hands.
Package boards with ESD packaging materials before storing or transporting them.
NOTICE
The static electricity generated by human bodies may damage the electrostatic-sensitive
components on boards, for example, the large-scale integrated (LSI) circuits.

1.4 Installation Environment Requirements
1.5 Mechanical Safety
Using Ladders
Figure 1-1 wearing an ESD wrist strap
If any liquid is detected inside the equipment, immediately disconnect the power supply and
contact the vendor.
Do not expose the equipment to flammable or explosive gas or smoke. Do not perform any
operation on the equipment in such environments.
The environmental temperature must be between 0 °C and +50 °C, and the relative humidity.
Between 0% and 90% (without condensation).
Install on a sturdy supported surface. Indoor installation only.
Use wooden or fiberglass ladders when you need to perform live working at heights.
When a step ladder is used, ensure that the pull ropes are secured and the ladder is held firm.
Before using a ladder, check that it is intact and confirm its load bearing capacity. Do not
overload it.
Ensure that the ladder is securely positioned. The recommended angle for a ladder against
the floor is 75 degrees, as shown in the following figure. An angle rule can be used to measure
the angle. Ensure that the wider end of the ladder is at the bottom, or protective measures have
been taken at the bottom to prevent the ladder from sliding.

DANGER
When removing a heavy or unstable component from a cabinet, be aware of unstable or heavy
objects on the cabinet.
NOTICE
Do not drill holes into the equipment. Doing so may affect the electromagnetic shielding of the
equipment and damage components or cables inside. Metal shavings from drilling may
short-circuit boards inside the equipment.
Drilling Holes
Moving Heavy Objects
Obtain the consent from the customer, subcontractor, and Redx before drilling.
Wear goggles and protective gloves when drilling holes.
When drilling holes, protect the equipment from shavings. After drilling, clean up any shavings that
have accumulated inside or outside the equipment.
When climbing a ladder, take the following precautions to reduce risks and ensure safety:
Keep your body steady.
Do not climb higher than the fourth rung of the ladder from the top.
Ensure that your body's center of gravity does not shift outside the legs of the ladder.
When drilling holes into a wall or floor, observe the following safety precautions:

1.6 Battery Safety
DANGER
Do not expose batteries at high temperatures or around heat-generating devices, such as
sunlight, fire sources, transformers, and heaters. Excessive heat exposure may cause the
batteries to explode.
Do not burn batteries. Otherwise, the batteries may explode.
To avoid leakage, overheating, fire, or explosions, do not disassemble, alter, or damage
batteries, for example, insert sundries into batteries or immerse batteries in water or other
liquids.
Basic Requirements
Be cautious to avoid injury when moving heavy objects.
When moving the equipment by hand, wear protective gloves to prevent injuries.
Move or lift the equipment by holding its handles or lower edges. Do not hold the handles of modules
(such as power supply units, fans, and boards) that are installed in the equipment because they
cannot support the weight of the equipment.
Avoid scratching the case surface or damaging case components and cables during equipment
transportation.
When transporting the equipment using a forklift truck, ensure that the forks are properly positioned to
ensure that the equipment does not topple. Before moving the equipment, secure it to the forklift truck
using ropes. When moving the equipment, assign dedicated personnel to take care of it.
Choose railways, sea, or a road with good condition for transportation to ensure equipment safety.
Avoid tilt or jolt during transportation.
Move a cabinet with caution. Any bumping or falling may damage the equipment.
Before operating batteries, carefully read the safety precautions for battery handling and master the
correct battery connection methods.

To ensure battery safety and battery management accuracy, use batteries provided with the
UPS by Redx. Redx is not responsible for any battery faults caused by batteries not provided
by Redx.
NOTICE
Wear goggles, rubber gloves, and protective clothing to prevent skin contact with electrolyte in the
case of electrolyte overflow. If a battery leaks, protect the skin or eyes from the leaking liquid. If the
skin or eyes come in contact with the leaking liquid, wash it immediately with clean water and go to
the hospital for medical treatment.
Use dedicated insulated tools.
Move batteries in the required direction. Do not place a battery upside down or tilt it.
Keep the battery loop disconnected during installation and maintenance.
Use batteries of specified models. Using batteries of other models may damage the batteries.
Dispose of waste batteries in accordance with local laws and regulations. Do not dispose of batteries
as household waste. If a battery is disposed of improperly, it may explode.
The site must be equipped with qualified fire extinguishing facilities, such as firefighting sands and
powder fire extinguishers.
Before installing batteries, observe the following safety precautions:
Install batteries in a well-ventilated, dry, and cool environment that is far away from heat sources,
flammable materials, moisture, extensive infrared radiation, organic solvents, and corrosive gases.
Take fire prevention measures.
Place and secure batteries horizontally.
Note the polarities when installing batteries. Do not short-circuit the positive and negative poles of
the same battery or battery string. Otherwise, the battery may be short-circuited.
Check battery connections periodically, ensuring that all bolts are securely tightened.
When installing batteries, do not place installation tools on the batteries.

WARNING
Battery Short Circuit
Lithium Battery
DANGER
Battery short circuits can generate high instantaneous current and release a great amount
of energy, which may cause equipment damage or personal injury.
To avoid battery short-circuit, do not maintain batteries with the power on.
The safety precautions for lithium batteries are similar to those for lead-acid batteries except that you
also need to note the precautions described in this section.
Battery short circuits can generate high instantaneous current and release a great amount
of energy, which may cause equipment damage or personal injury.
There is a risk of explosion if a battery is replaced with an incorrect model.
A battery can be replaced only with a battery of the same or similar model recommended by the
manufacturer.
When handling a lithium battery, do not place it upside down, tilt it, or bump it with other objects.
Keep the lithium battery loop disconnected during installation and maintenance.
Do not charge a battery when the ambient temperature is below the lower limit of the operating
temperature (charging is forbidden at 0°C). Low-temperature charging may cause crystallization,
which will result in a short circuit inside the battery.
Use batteries within the allowed temperature range; otherwise, the battery performance and safety
will be compromised.
Do not throw a lithium battery in fire.
When maintenance is complete, return the waste lithium battery to the maintenance office.
