grounding. Contact with any part of a grounded battery can result in electric shock.

Do not attempt to open or disassemble batteries. The electrolyte is harmful to the skin and eyes. The battery
contains diluted sulfuric acid, which is extremely toxic. If a battery leaks, take appropriate measures to
prevent any battery fluid contacting your skin or clothing. Diluted sulfuric acid may cause blindness if it
gets into the eye, may burn skin upon contact. It is electrically conductive and corrosive. Observe the
following procedures if electrolyte spills:
a. Wear full eye protection and protective clothing.
b. If sulfuric acid contacts the skin, wash it off immediately with water.
c. If sulfuric acid contacts the eyes, flush thoroughly and immediately with water, and seek medical

attention.

d. Spilled sulfuric acid should be washed down with a suitable acid-neutralizing agent, such as a solution

of approximately one pound (500 grams) bicarbonate of soda in one gallon (4 liters) of water. The
bicarbonate of soda solution should be applied until evidence of reaction (foaming) has ceased. The
resulting liquid should be flushed with water and the area dried.

Lead acid batteries can present a risk of fire due to generation of hydrogen gas. The following procedures
should always be followed:
a. DO NOT SMOKE when near batteries.
b. DO NOT allow flames or sparks near batteries.
c. Before working with batteries, discharge static electricity from the body by first touching a grounded

metal surface before touching the batteries.
Do not dispose of batteries in fire, as they could explode.
If a fire occurs near a battery, do not use water to extinguish it. Use only a powder-distinguishing agent

(ABC). Using water can cause the fire to spread.

Strictly observe the following precautions when handling the batteries. Failure to do so may cause battery

leakage, overheating or explosion.
a. Do not solder to any part of the battery directly.
b. Do not charge the battery with reversed positive (+) and negative (-) terminal polarity.
c. Do not mix different battery types, brands or versions.
d. Do not attempt to peel off or break the outer covering of a battery.
e. Do not subject batteries to strong physical shock, or throw them away.

2. For Proper Operation

2.1 Input Power Requirements

(1) Please use UPS as a commercial power supply in the region and the output voltage of UPS

are matched referring to the table below.

MODEL AC input voltage AC input frequency NOTE

E11A202U001 120V (+15%,-20%) 50 or 60Hz (±5%)

※

E11A202U001J 100,110,115,120V (+15%,-20%) 50 or 60Hz (±5%)

The frequency variation range is set to ±3% when the UPS is shipped from the factory.
If the frequency variation range of input power supply is

③

“Frequency sync range” of §10.1 “Setup Menu Item List”. An input power error occurs when
the frequency sync range exceeds the setting value, preventing the UPS from switching to
inverter operation.

±

5%, select ±5% as described in item

(2) The current capacity of the AC power supply must satisfy the requirements of the UPS

(It is different depending on the model.)

MODEL Input capacity Recommended capacity of breaker

E11A202U001 1.8kVA 20A or more (Demand of UL rules)

E11A202U001J 1.8kVA 30A or more (Demand of UL rules) *

*NOTE: Please set up Branch circuit protector of 30A in the switchboard for E11A202U001J.

In branch circuit protector, please protect two poles of the ac input.

(Demand of UL rules)

2.2 Installation Precautions

※

※

* Installation must be in accordance with the National Electric Code Articles 110-17 and 110-18.

(1) Carefully consider the leakage current when a leakage circuit breaker is installed on the

input side. The maximum leakage current of the UPS is 3mA.

(2) Keep the UPS at least 1 m (about 40 inches) away from CRT displays. Other devices which

may be sensitive to magnetic flux should be kept away from the UPS, as it emits a slight
amount of magnetic flux.

(3) The UPS employs a fan for forced-air cooling. Provide at least 20 cm (about 8 inches)

clearance at the front and back of the UPS to permit free airflow at the air intake and
exhaust vents. Also, for maintenance purposes, a space of at least 1 m (about 40 inches) will
be needed at the front of the UPS and a space of at least 50 cm (about 20 inches) will be
needed at the back of the UPS.
When mounting the UPS in a rack, use a rack which allows ventilation and provide at least
20 cm (about 8 inches) clearance from the front and back of the rack to permit free airflow at
the air intake and exhaust vents. Also, for maintenance purposes, a space of at least 1 m
(about 40 inches) will be needed at the front of the rack, and a space of at least 50 cm (about
20 inches) will be needed at the back of the rack.
For details, see §6.3 “Installation Space”.

(4) When the AC input power is single-wire grounded, always connect the ground phase to the S

terminal (phase) side on the UPS.

(5) As far as possible, do not ground the output (load) side. If you must make a single-wire

grounded connection, always connect the ground phase to the V terminal (phase) side on the
UPS. (This is to prevent short-circuiting by the ground.)

2.3 Usage Precautions

(1) Never short-circuit the output terminals, or connect a load which draws short-circuit current.

Doing so causes protective functions to activate or the circuit breakers to trip, preventing
output.

(2) Unsuitable load devices

Do not connect laser printers, plain paper fax machines, copy machines, or overhead
projectors as load devices. Such devices typically include heating elements that draw high
current. This may cause an overload that could prevent battery backup operation when an
outage occurs, and could damage the UPS.

−

6 −

(3) Power supply environment

If the UPS is used in an environment subject to long and frequent power outages (more than
once a week), the batteries may not receive sufficient charge, which could result in
foreshortened battery life and premature battery failure.

(4) If the UPS is not operated for a long period, the batteries may require recharging. Operate

the UPS with no load to recharge the batteries as indicated in the following table, according
to the storage temperature. If the batteries in the UPS are left uncharged, their service life
will be greatly foreshortened.

Storage Temperature Charge Interval No-Load Operation
25°C (77°F) Once every 6 months At least 20 hours
30°C (86°F) Once every 4 months At least 20 hours
40°C (104°F) Once every 2 months At least 20 hours

(5) Insulation testing

Before testing indoor wiring insulation, shut down the UPS and disconnect the input and
output cables. Conducting an insulation test with the UPS connected may damage electronic
components such as the built-in arrester.

(6) Rack support rails (not supplied) are required to mount the UPS on a rack. For details,

contact your supplier or Sanyo Denki representative.

2.4 Dealing with Errors

Contact your supplier or Sanyo Denki representative if any of the following occur.
(1) The red ALARM indicator lights (except when the UPS stops because of a prolonged power

outage).

(2) The green INV.ON/STAND BY indicator, green INPUT indicator, or green OUTPUT indicator

does not light even when the UPS is operated properly.

(3) Another condition occurs which you suspect is caused by a failure in the UPS.

4. Overview

The SANUPS E11A is a stationary-type uninterruptible power supply designed to provide
high-quality, stable AC power to critical equipment that requires continuous,
uninterrupted power.
The UPS is comprised of rectifier, charger, inverter, battery, and utility power transfer
(bypass) circuits. In the event of failure of the AC utility power source, AC output to the
load is sustained by the inverter converting DC power from the batteries. When the utility
power recovers, inverter operation continues while the batteries are recharged. The UPS
is therefore able to supply completely uninterrupted AC power to connected loads without
even momentary power loss.

CAUTION

(1) Battery backup time confirmation

Refer to §11.5 “Battery Test”, and periodically perform a battery backup time test.
Depending on the results of the test, exchange the battery.
The default Setup menu setting is to perform an automatic battery test once every 6
months.

(2) Estimated battery replacement interval

Battery service life is affected by operating conditions such as ambient temperature
and the number of discharge cycles. Ambient temperature has a particularly strong
influence as indicated in the following table (refer to the table to predict when
batteries will need to be replaced according to average ambient temperature). Using
batteries after their service life has expired can cause leakage, and in the worst case
damage may result, so we recommend exchanging batteries early as a preventative
and protective step.

15. Functional Description

15.1 Basic Operation

(1) Normal Operation

In normal operation, the UPS switches automatically
depending on the state of the power.

*

The UPS does not switch automatically when item ① “UPS operation mode” in §10.1

“Setup Menu Item List” is set to “Double Conversion”.
However,The UPS switch automatically according to the state of the input power and the
load condition when item

①

"UPS operation mode" in §10.1 "Setup Menu Item List" is

set to "Economy".

(a) Active Filter mode

The UPS operates in Active Filter mode when the input power voltage is within a
certain range and the output power factor is below a certain value. In Active Filter
mode, the UPS receives power from the utility power source and supplies it to the load.
At the same time, it compensates for high frequencies in the input power at the
inverter. The batteries are kept continually charged and ready in case a problem
(outage or voltage drop) occurs in the utility supply.

(b) Double Conversion mode

The UPS switches to Double Conversion mode when the input power voltage is outside
a certain range. In Double Conversion mode, the UPS converts AC power from the
utility power source into DC power through the rectifier, and reconverts this DC power
back into AC power through the inverter and supplies it to the load. The output power
is stable AC power synchronized with the input power source. The batteries are kept
continually charged and ready in case a problem (outage or voltage drop) occurs in the
utility supply

(c) Economy mode

The UPS switches to Economy mode when the input power voltage is within a certain
range and the output power factor is above a certain value. In Economy mode, the UPS
receives power from the utility power source and supplies it to the load. At the same
time, the inverter is connected to the load and ready to activate. The batteries are kept
continually charged and ready in case a problem (outage or voltage drop) occurs in the
utility supply.

(2) On Failure of Utility Power

When a fault or an outage occurs in the utility power source, the rectifier and charger
cease operating while inverter operation continues, now using the batteries as a DC source
to produce AC voltage, to ensure stable power supply to the load without even a
momentary power dropout. At the same time, the buzzer sounds the battery operation
alarm, and the green INPUT indicator starts blinking.

(3) Upon Recovery of Utility Power

When normal utility power is restored, rectifier and charger operations resume
automatically, returning to the normal operating state described in §15.1 (1).

(4) When Battery Voltage Declines

When low voltage or an outage in the utility power source continues, causing the battery
voltage to decline to about 45V (1.85V/cell), the red BATT.LOW indicator in the above
figure lights to indicate low battery voltage.

Note: When item

⑫

“Low battery voltage signal timing” in §10.1 “Setup Menu Item List”
is set to “2 minutes” or “3 minutes”, the alarm is issued at the point when the
remaining battery time drops to the specified level.

(5) Extended Power Outage

If a power outage persists and the battery voltage reaches the final discharge level, a
protective circuit shuts off the inverter to prevent over-discharging of the batteries. When
normal utility power recovers after the inverter has been stopped automatically, operation
is automatically resumed, returning to the normal operating state described in §15.1 (1).

Note: When item

⑦

“Restart time” in §10.1 “Setup Menu Item List” is set to “OFF”,
inverter output remains stopped. When it is set to “30%”, “50%”, or “80%”, the UPS
restarts operation once the batteries are charged to the specified level and then
returns to the normal operating state described in §15.1 (1).

15.2 Protective Functions

(1) Overload Protection

If the UPS output is overloaded by exceeding the current capacity of the inverter, such as
when a computer system boots up, the output selector switch automatically switches the
source of AC power from the inverter to the bypass circuit, without interruption. After a
certain period of time has elapsed, the source of power to the load is switched back to the
inverter without interruption (auto-return), as shown in §15.1(1).

Note: When item

to “Bypass”, the UPS switches to inverter power supply without interruption when
the overload is resolved.

Utility
power

(2) Inverter Fault Protection

If a fault occurs in the inverter, the output selector switch activates automatically and
switches from inverter power to bypass power without interruption. The red ALARM
indicator lights, and the alarm buzzer sounds. The power supply route is the same as for

an overload. Press

Note: What to do if an inverter fault occurs

Output from the UPS will stop if a power outage occurs during bypass operation due
to an inverter fault. Contact your supplier or a Sanyo Denki representative as soon
as possible.

Appendix. Usage notes for SANUPS SOFTWARE STANDALONE

When using supplied “SANUPS SOFTWARE STANDALONE”, please note the following
instructions.

“Charge” on the main screen of “SANUPS SOFTWARE STANDALONE”

For the charge rate (as a %) of the battery displayed on the main screen of “SANUPS
SOFTWARE STANDALONE”, please note the followings.
Refer to §6.1 “Main Screen” in the User Guide of SANUPS SOFTWARE STANDALONE for
details.

1. Proceed as follows to charge the batteries of the UPS for 12 hours or more at initial startup
of the UPS.

（

Use the internal battery only.）

Perform this operation before powering the connected load devices on.

①

Verify that the battery connector is connected correctly.
See §6.4 “Preparation Before Installation” in the E11A Instruction Manual for details.

②

Perform step “§9.1 ①” in the E11A Instruction Manual.

③

Verify that the Green INPUT LED on the UPS control panel lights.
Charging starts automatically.

④

Keep the UPS in the condition of step ③ for 12 hours or more.

However, you use the Battery Modules (Option), in the following list.

Battery Modules

BC-E11A202US×1unit

BC-E11A202US×2 unit

BC-E11A202US×3 unit

BC-E11A202USL×1 unit

BC-E11A202USL×2 unit

Charge time

36 hours or more

60 hours or more

84 hours or more

48 hours or more

84 hours or more

2. If the UPS is stopped and then restarted, even when the UPS is charged by step 1,
“Charge” might be displayed as “80%” or “90%” not “100%” on the main screen.
This occurs owing to the operating conditions such as ambient temperature.
However after normal operation of the UPS for 1 or 2 hours, “Charge” is displayed properly.

But if you use the Battery Modules (Option), after normal operation of the UPS for 2 hours
or more, “Charge” is displayed properly.

3. Connect the battery connector correctly. If the UPS is operated without the batteries,
“Charge” is not displayed properly. Moreover, even if the battery connector is reconnected
and operates the UPS, the proper charge rate is not displayed immediately.
After normal operation of the UPS for 12 hours or more, “Charge” is displayed properly.

4. Display of “Charge” is only an approximation. An actual charge rate of the battery might be
different.

“Backup Time” on the main screen of “SANUPS SOFTWARE STANDALONE”

For the presumed “Backup Time” (in minutes) displayed on the main screen of “SANUPS
SOFTWARE STANDALONE”, please note the followings.
Refer to §6.1 “Main Screen” in the User Guide of SANUPS SOFTWARE STANDALONE for
details.

−

42 −

1. In §6.4 (1) “Setting the shutdown trigger conditions”, if “When the battery-low occurs,
shutdown execution” is selected as the shutdown trigger conditions, set the time more than
40% of the presumed backup time displayed on the main screen.
Refer to §6.4 “Setting the Shutdown Conditions” in the User Guide of SANUPS SOFTWARE
STANDALONE for details.

2. If the “Load” displayed on the main screen is less than 30%, the presumed backup time
sometimes shows improper value. Therefore “When the battery-low occurs, shutdown
execution” feature is not recommended to use with such a low load factor condition.

3. The presumed backup time is only an approximation. An actual backup time might be
different.
