KNOWING Y OUR HOME UPS
Now lets begin the journey to explore various aspect of your Su-Kam Digital
Home UPS. Welcome aboard!
In its most basic form, an Digital Home UPS transforms Direct Current (DC) to
Alternating Current (AC). The battery bank with the Digital Home UPS acts as a
reservoir to ensure continuous supply of power whenever mains supply from
utility power is not available.
On the front panel of the digital Home UPS there is one Power Active switch and
a graphical symbol panel, for indications.
1. MAINS ON : This white graphical symbol, when lit, indicates that incoming
mains is available.
2. INV. ON : This white graphical symbol shows that incoming mains is not
available and the output is from Home UPS.
3. BATT. CHARGING / CHARGED : This white graphical symbol, shows
that the incoming mains is available and simultaneously the battery is also
being charged . This white graphical symbol, glows intermittently during
charging and glows continuously when battery is charged.
4. FUSE BLOWN : Mains fuse blows off when the Home UPS is operating on
mains and the load connected through the Home UPS exceeds the specified
limits prescribed for the Home UPS. In this case, at once reduce the extra
load and replace the glass fuse given at back to restore the mains line. During
this stage, the Mains ON graphical symbol, glows intermittently with buzzer
beeps .

5. LOW BATT. : This graphical symbol, appeals when battery voltage goes
down to a low limit during discharge. The Digital home UPS will shut
down automatically after a few minutes. During this stage the graphical
symbol glows and the buzzer gives continuous beep.
6. O.L. / SHORT CIRCUIT : This graphical symbol, shows that either
Short circuit has occurred or there is overload on the Home UPS. The
Digital Home UPS resets itself automatically and makes 8 attempts in
case of overload and 4 attempts in case of short circuit to switch ON. If
the overload or short circuit continues even after these attempts, the
Digital Home UPS switches OFF and will switch ON only after the
power active switch is first OFF and then put ON. In the event of
unsuccessful attempts the Digital Home UPS automatically shuts down.
During overload or short circuit the graphical symbol glows and the
buzzer gives a intermittent beep. If there is short circuit at the output,
the Digital Home UPS will switch OFF permanently after a few attempts.
It can be reset by repairing the short circuit and then switching OFF and
ON the power active switch.
7. POWER ACTIVE SWITCH : The latching ON/OFF switch in the front is
to be pressed to ensure that the Digital Home UPS switch on in the event of
mains failure and connected load is energised by Digital Home UPS.

The has two battery wires coming out from the rear side,
a Fuse holder, 2 toggle switches, an output Socket and an input mains
or 3 way cable .We connect the two battery wires to the terminals of the
battery, the red coloured to positive terminal and the black coloured to the
negative. A three core input cable has to be used to connect the
to incoming AC Mains. Ensure that incoming phase (or line) is
connected to line (Red wire) neutral is connected to neutral (Black Wire)
and earth is connected to earth (Green Wire). After this the output is
connected through the output socket at the rear of the

IMPORTANT SAFETY INSTRUCTIONS
Before proceeding further kindly go through the safety instructions
carefully.
General Precautions:
1. Before using the Home UPS read all instructions and cautionary markings
on the Home UPS, the Batteries, all appropriate section of this instruction
manual.
2. Do not expose Home UPS to rain, liquids of any type. The Home UPS is
designed for interiors only.
3. Do not disassemble the Home UPS, take it to a Su-Kam Engineering
Service Centre when service or repair is required. Opening by unqualified
personnel entails electric shock or fire hazard.
4. To reduce risk of electric shock, disconnect all wiring before cleaning.

8. Be extra cautious when working with metal tools on and around batteries.
It could short-circuit the batteries or other electrical parts, producing a spark
that could cause an explosion.
9. Remove conductive jewelry such as rings, bracelets, necklaces, and watches
when working with a battery. A battery can produce a short-circuit current
high enough to weld a ring or causing severe burns.
5. Warning-Risk of Explosive gases
WORKING IN THE VICINITY OF A LEAD ACID BATTERY
MAY BE DANGEROUS. BATTERIES GENERATE EXPLOSIVE
GASES DURING NORMAL OPERATION.
Provide ventilation to outdoors from the Battery compartment.
The battery enclosures should be designed to prevent accumulation and
concentration of hydrogen gas in“pockets’’ at the top of the compartment.
V ent the battery compartment from the highest point. A sloped lid can also be
used to direct the flow to the vent opening location. To reduce the risk of
battery explosion, follow all the instructions of batteries supplier or any
equipment you intend to use in the vicinity of batteries.
6. Do not cover your Home UPS with any cover or cloth.
7. Do not install this Home UPS on or near flammable materials (plywood,
Chemicals, gasoline etc.).

Safety
Instructions

Special Notices:
!Do not switch on the heavy load TV, Refrigerators, Motor, Cooler, etc when
Home UPS is running on battery backup and is in UPS mode. This may
cause rebooting of your computer.
!Avoid connecting the stabilizer between utility power and Home UPS. The
AVR of stabilizer may cause your computer to reboot.
!We recommend that you have point to point wiring of the Home UPS.
GROUNDING INSTRUCTIONS: This Home UPS must be
connected to a grounded, permanent wiring system.
!
IMPORTANT PRECAUTIONS:
The output side of the AC wiring should never be connected to a
generator or incoming utility power. This condition is far worse than a short
circuit. If the unit survives this condition, it will shut down until correction is
made.
Note : Never disconnect the battery cables while the is delivering
power or battery charger is operating. The Power Active Switch has no effect on
the charger; it turns off only the power output during backup mode. To disconnect
the batteries for service:
(a) turn off the power switch.
(b) disconnect all AC power.
(c) disconnect all the battery cables.
