connection and battery polarity to ensure correct connection. In order to ensure
personal safety and the normal use of UPS, UPS shall be reliably grounded before
use.
UPS can be used for resistive and capacitive (such as computers), resistive and
micro inductive load, not for pure capacitive and inductive load (such as motors,
air conditioners and copiers) and half wave rectifier load.
When cleaning the machine, please wipe it with a dry object. Under no
circumstances shall water be used to clean electrical parts inside or outside the
cabinet.
After completion of maintenance operations, check immediately to ensure that no
tools or other items are left in the cabinet.
In case of fire, please use dry powder extinguisher correctly for extinguishment.
There is a danger of electric shock if liquid fire extinguishers are used.
Do not close the breaker before the UPS installation is completed. Do not power
on UPS without the permission of a qualified electrician.
Battery Safety
Battery installation and maintenance shall only be performed by personnel with
battery expertise.
There is danger of electric shock and short circuit current in the battery. In order
to avoid safety accidents, when installing or replacing the battery, please pay
attention to the following matters: do not wear jewelry and watches and other
conductive objects; use special insulation tools; use facial protection; wear
protective insulating clothing; do not turn the battery upside down or tilt it;
disconnect the input breaker of the battery.
The installation environment of the battery must be far away from the hot area,
and it is not allowed to use or keep the battery near the fire source. The battery or
battery strings cannot be processed by fire, otherwise it is possible cause personal
injury due to explosion.
Environmental factors impact battery life. Elevated ambient temperatures, poor
quality utility power, and frequent short duration discharges will shorten battery
life.
The batteries should be regularly replaced to ensure the normal operation of UPS
and sufficient backup time.
Do not use a battery that is not approved by the supplier, as it may adversely
affect the operation of the system. Use of a non supplier approved battery will
void the manufacturer warranty.
Check the screws of the connecting parts of the battery regularly to make sure
they are tight and not loose. If the screws become loose parts, they must be
tightened immediately.
Please do not short the positive and negative terminals of the battery, Otherwise it
is possible to cause electric shock or fire.
Do not touch the wiring terminal of the battery. The battery circuit is not isolated
from the input voltage circuit, and there will be a high voltage hazard between the
battery terminal and the ground.
Do not open or damage the battery, otherwise it is possible to cause short circuit
and battery leakage and the electrolyte in the battery may cause damage to the
