Chapter 1 Safety Instruction
This manual contains important instructions that you should follow during installation and maintenance of the
UPS and batteries. Please read all instructions before operating the equipment and save this manual for
future reference.
Strictly follow the Safety instruction for equipment installation, operation and maintenance, inappropriate
operation may cause injury to personnel and equipment. Manufacturer assume no responsibility for violation
of operation.
Danger
This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by AUTHORIZED
SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE PARTS inside the UPS.
CUT OFF all power supply before any installation and manipulation of power wiring.
Reverse connection polarity, short-circuit of battery terminal may cause harmful high current, or even fire,
make sure proper connect battery.
Cable with sufficient current rating should be used for wiring, secure fixation and proper insulation are all
required to avoid fire accident cause by wired overheat or short-circuit.
Warning
This UPS contains its own energy source (batteries). The UPS output may carry live voltage even when
the UPS is not connected to an AC supply.
To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity controlled,
indoor environment, free of conductive contaminants. Ambient temperature must not exceed 40°C
(104°F). Do not operate near water or excessive humidity (90% maximum).
To reduce the risk of fire, connect only to a circuit provided with branch circuit over-current protection .
Output over current protection and disconnect switch must be provided by others.
To comply with international standards and wiring regulations, the sum of the leakage current of the UPS
and the total equipment connected to the output of this UPS must not have an earth leakage current
greater than 3.5 milliamperes.
If installing optional rack-mount Battery Pack, install the Battery Pack directly below the UPS so that all
wiring between the cabinets is installed behind the front covers and is inaccessible to users.
Caution
Batteries can present a risk of electrical shock or burn from high short-circuit current. Observe proper
precautions. Servicing should be performed by qualified service personnel knowledge of batteries and
required precautions. Keep unauthorized personnel away from batteries.
Proper disposal of batteries is required. Refer to your local codes for disposal requirements.
Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
In the event of fire occurring in the vicinity, please use dry powder fire extinguishers. The use of liquid
fire extinguishing agents may cause electric shock.
