Safety Guidelines
. Prohibitions
1. As high voltage exists within UPS, no one but Avansys
technician and Avansys-authorized technician should open the
panel and the chassis cover. Otherwise, one may get electric
shock and such situation is not covered under warranty.
2 2. When the UPS is purchased to supply the equipment listed
below, please consult the distributor in advance on the UPS
application, setting, management and maintenance, which need
special consideration and design.
Life support medical apparatus;
Facilities such as lift which may endanger human life;
Mission-critical equipment like above.
3. Never dispose of battery in a fire, as battery may explode
when exposed to flame.
. Matters needing attention
1. The UPS contains its own energy source-battery, the UPS
output may carry live voltage even when the UPS is not
connected to an AC supply.
2. To move or re-wire the UPS, please disconnect the input and
make sure that the UPS is completely shut down. Otherwise, live
voltage still exists at the output terminal, which may cause
electric shock.
3. To ensure human safety, the UPS must be reliably grounded
before use.

4. The operating environment and storage method will affect the
lifetime and reliability of the UPS. Please don’t use the UPS long
in the following environments
Place with temperature and relative humidity outside
specifications (temperature: 0 to 40 , relative humidity: 5% to
95%);
Place with direct sunlight or near heat source;
Place with vibration or shock;
Place with dust, corrosive material, salt or flammable gas.
5. Please keep the air inlet and outlet unblocked. Poor ventilation
will increase the internal temperature, which will shorten the
lifetime of the UPS components, hence that of the UPS.
6. Liquid and other irrelevant substances are strictly prohibited
inside the UPS chassis.
7. In case of fire, please use dry-chemical fire extinguisher. Using
foam fire extinguisher may cause electric shock.
8. High ambient temperature shortens battery lifetime, so battery
should be replaced regularly to ensure normal UPS operation
and adequate backup time. Battery replacement must be
conducted by authorized technician.
9. If the UPS will not be used for long, it should be placed in dry
environment. Storage temperature of standard UPS (with battery):
–20 +55 , storage temperature of long backup time UPS
(without battery): –40 +70 .
10. During the period the UPS is left unused, it is recommended
to supply the UPS with AC mains for more than 12 hours every 3
months, so that the battery will not be damaged due to long time
of not-in-use.

11. Please don’t open or damage the battery, as the electrolyte is
harmful to skin and eye. If tainted with electrolyte, wash it off
immediately with plenty of water and go to hospital for a check.
