•

Do not open or mutilate the battery or batteries. The battery contains dilute sulfuric acid, which

is extremely toxic. If the battery fluid leaks, take approximate measures so that the leak battery
fluid is not sticking to your skin or clothing. If dilute sulfuric acid enters your eye, this may
cause eyesight to be lost. Additionally, if dilute sulfuric acid is in contact with your skin, this
may cause a burn.

It is electrically conductive and corrosive. The following procedures

CAUTION

should be observed:
a. War full eye protection and protective clothing.
b. If electrolyte contacts the skin, wash it off immediately with water.
c. If electrolyte contacts the eyes flush thoroughly and immediately with water. Seek

medical attention.

d. Spilled electrolyte should be washed down with a suitable acid neutralizing agent. A

common practice is to use a solution of approximately one pound (500 grams)
bicarbonate of soda to approximately one gallon (4 liters) of water. The bicarbonate of
soda solution should be added unit the evidence of reaction (foaming) has ceased. The
resulting liquid should be flushed with water and the area dried.

short-circuited. Doing so, output circuit cannot be supplied due to protection function
working and fuse breaking.

(2) Load units prohibited to connect

Laser printer, plain paper facsimile machine, copy machine, OHP, drier
In the load units listed above, when the heater is heated, a large current is flown and
over-load may occur. If this occurs, the battery backup may not function or the UPS
may be broken.

(3) Power supply environment

If the UPS is used under the condition that power failure is occurred frequently for a
long time (once a week or more), battery may not be charged sufficiently, or battery
service life may become short due to battery deterioration.

(4) If the UPS is not operated for 6 months or more, it may need to charge the battery.

Carry out no-load operation for 20 hrs. or more once every 6 months.

(5) Insulation test

4. Outline

This equipment is a stationary type uninterruptible power system that supplies good and

stable AC power to an important unit, which does not allow even instantaneous power shut-off.

The system makes basic unit of 3.5kVA, which is composed of a rectifier, charger, an inverter,
a battery, and commercial power transmission circuit (bypass circuit) work two or three units
together without common parts. This is possible to increase and decrease output capacity.

Even if an error occurs in the AC input power supply, the inverter operation is continued by
the DC power supplied from the battery. If the AC input power supply is recovered, the inverter
operation is continued while charging the battery. Therefore, the UPS supplies completely
uninterruptible AC power to the loads connected without even instantaneous power shut-off.

In case set to parallel redundancy method which has one unit capacity to equipment
capacity for load capacity, if the inverter malfunctions occurs, malfunction unit is cut
automatically, and inverter supply from normal unit is continued.
