This UPS full complies with “IEC62040-1-1-General and safety
requirements for use in operator access area UPS”. Dangerous
voltages are present within the battery box.
However, the risk of contact with these high voltages is minimized
for non-service personnel. Since the component with dangerous
voltage can only be touched by opening the protective cover with
a tool, the possibility of touching high voltage component is
minimized. No risk exists to any personnel when operating the
equipment in the normal manner, following the recommended
operating procedures in this manual.
Battery Safety
⟡
All the battery maintenance and servicing procedures
involving internal access need special tools or keys and
should be carried out only by trained personnel.
⟡
When connected together, the battery terminal voltage will
exceed 200Vdc and is potentially lethal.
⟡
Battery manufacturers supply details of the necessary
precautions to be observed when working on, or in the
vicinity of a large bank of battery cells. These precautions
should be followed implicitly at all times. Particular attention
should be paid to the recommendations concerning local
environmental conditions and the provision of protective
clothing, first aid and fire-fighting facilities.
⟡
Ambient temperature is a major factor in determining the
battery capacity and life. The nominal operating temperature
of battery is 20
℃
. Operating above this temperature will
reduce the battery life. Periodically change the battery
according to the battery user manuals to ensure the back-up
time of UPS.
⟡
Replace the batteries only with the same type and the same
number, or it may cause explosion or poor performance.
⟡
When connecting the battery, follow the precautions for high-
voltage operation before accepting and using the battery,
check the appearance of the batteries. If the package is
damaged, or the battery terminal is dirty, corroded or rusted
or the shell is broken, deformed or has leakage, replace it
with new product. Otherwise, battery capacity reduction,
electric leakage or fire may be caused.
