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. 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.

I. Functions
For heat dissipation of UPS.Air inlet
There are several LED indicators on the panel, showing the UPS state,
load, battery backup capacity, fault, etc.
LED
When the UPS is supplying power through inverter, pressing and
holding this button for 1 second can stop the inverter output (i.e., turn off
the inverter).
OFF button
When the UPS is supplying power through bypass, pressing and holding
this button for 1 second can start the inverter output (i.e., turn on the
inverter); when the UPS is supplying power through inverter, which
obtains power from rectifier, pressing and holding this button for 4
seconds can perform manual battery test; when the UPS is giving
audible alarm, pressing this button can silence the alarm sound.

II. LED
The LED indicators on the panel are divided into 2 groups according
to their use: one group indicates the load, battery backup capacity or
fault, totally 5 LED indicators, 4 green and 1 yellow; the other group
indicates the UPS state, including the mains indicator, battery
indicator, bypass indicator, inverter indicator and fault indicator.
Below is the detailed description of these indicators:
1. UPS state indicators
The light shines in the event of fault, and goes off
otherwise.
Fault indicator
red
The light shines when the inverter is supplying
power, goes off otherwise, and flashes in the event
of inverter fault.
Inverter indicator
green
The light shines when the battery is supplying
power, goes off otherwise, and flashes in the event
of charger fault, improper battery connection,
reverse battery connection, or battery fault.
Battery indicator
green
The light shines when the bypass is supplying
power, and goes off otherwise.
Bypass indicator
green
The light shines when the mains is normal, goes off
in the event of mains failure, and flashes when the
mains voltage is outside tolerances.
Mains indicator
green
2. Load, battery backup capacity/fault locating indicators
When the AC mains is working normally during UPS operation,
these indicators indicate the load, as described in the following
table:
Chapter 1 Product Introduction 7
E1-20010915-C-1.0

4 green lights and 1 yellow light shining
indicates the UPS assumes more than 95%
rated load
4 green lights shining indicates the UPS
assumes 75%--95% rated load
3 green lights shining indicates the UPS
assumes 55%--75% rated load
2 green lights shining indicates the UPS
assumes 35%--55% rated load
1 green light shining indicates the UPS
assumes 0--35% rated load
When the battery is supplying load, these indicators indicate the
battery backup capacity, as detailed in the following table:
The yellow light shining means the battery is approaching
discharge termination voltage, and the UPS is about to
stop output
1 green light shining means the battery backup capacity is
greater than 20% rated capacity
2 green lights shining means the battery backup capacity
is greater than 40% rated capacity
3 green lights shining means the battery backup capacity
is greater than 60% rated capacity
4 green lights shining means the battery backup capacity
is greater than 80% rated capacity
In the event of UPS fault (the fault indicator shines), these indicators
tell the fault reason (as shown in the following table), so that the fault
can be located quickly.
