other property.
NOTICE!
WARNING!
This UPS unit contains hazardous AC and DC voltages. Only qualified electricians should
connect the UPS, AC line and external batteries, and must be familiar with batteries and battery
installation.
Before installing, maintaining or servicing the UPS, shut off the UPS and disconnect all sources
of AC and DC power.
As the UPS has no built-in disconnection devices to switch off external AC and DC input power,
ensure that disconnection devices are available as separate parts in connection with the
installation.
The installer must provide each external disconnecting device for this UPS system with labels
with the following text:
“Isolate the Uninterruptible Power Supply (UPS) as instructed in this guide before working on
circuit”
AC and/or DC voltage will always involve a potential risk of AC voltage at UPS output generated
from either batteries or utility. To avoid equipment damage or personal injury, always assume
that there may be voltage at UPS output.
This system is equipped with an auto-start function. If activated, the system may start without
warning. Refer to the “Programming” section for information on de-activation.
Indicates a hazard which, if not avoided, could result in injury or death.
Indicates a hazard which, if not avoided, could result in damage to the product or
Read and pay attention to this important information.
TEST BEFORE YOU TOUCH!
To reduce the risk of fire or electric shocks, install the UPS and external batteries in a
temperature and humidity controlled indoor area, free of conductive contaminants.
UPS batteries are high-current sources. Shorting battery terminals, DC terminals or DC busbars
can cause severe arcing, equipment damage and injury. A short circuit can cause a battery to
explode. Always wear protective clothing and eye protection and use insulated tools when
working on batteries.
CAUTION!
This unit contains components sensitive to electrostatic discharge (ESD). If you do not follow the
ESD procedures, you may cause severe damage to electronic components.
PLEASE RECYCLE
The shipping materials are recyclable. Please save for later use or dispose of them appropriately.

Introduction
1.0Introduction
This UPS system is designed to offer reliable and problem-free power supply for several years.
The system requires only a minimum of maintenance, but we recommend you follow the
maintenance guidelines described in the “Maintenance & Testing” section of this User Guide.
1.1Display Unit
The display unit (located on the front of the UPS) is the link between the user and the UPS and
consists of a display, an alarm LED indicator and a keyboard. The display reads parameters,
measured values and alarm messages.

WARNING!
AC voltage generated either from batteries or utility may be present at UPS output. Always
disconnect AC input supply source, switch off UPS, AND switch off DC.
TEST BEFORE YOU TOUCH!
Some UPS systems have a factory-set auto-start feature, which automatically switches on the
UPS whenever utility supply is switched on (AC line). See the “Parameter Settings” section in
this User Guide for instructions on how to de-activate this function.
Only qualified electricians should start up or shut down APC BC300 Series UPS systems, and
instructions in the Installation Guide should be followed. The UPS must be completely shut
down before service or before the UPS is taken out of operation for more than 24 hours.
Although you cannot completely start or shut down the unit, you can switch the UPS into
stand-by mode and return it to normal operation by following the instructions below. (In standby mode, the UPS does not provide output voltage.)
2.1UPS Stop (for stand-by)
To put the unit into stand-by mode, press the red control button inside the unit’s front door.
2.2UPS Start (from stand-by)
To take the unit out of stand-by and switch it back to normal operation, press the
green control button inside the unit’s front door.
.
NOTICE!
Make sure the UPS operates in normal operation for at least 12 hours every three months to
recharge the batteries.

Operation Mode Description
The UPS is in the normal operation mode. During normal operation,
utility (AC line) passes through the UPS and to the load. The inverter
regulates the output and charges the batteries. The UPS measures
all three phases, and the display reads out the% load of the highest
loaded phase.
When AC input is out of tolerance (outside programmed limits), the
UPS is running in battery mode. The main static switch is open, and
the inverter is powered from the batteries. The power is then fed to
the loads. If the batteries are depleted, the unit will switch to standby mode (see below) and wait for utility to return in tolerance. If autostart is programmed to “ON,” the unit will automatically start about
30 seconds after utility has returned. If auto-start is programmed to
“OFF,” you must start the unit manually by pressing the green
button inside the front door. (See the “Parameter Settings” section in
this User Guide.)
through the main transformer, and to the loads. The UPS’ inverter is
in stand-by and is synchronized to the utility, ready to transfer the
unit to battery operation if utility voltage is out of tolerance.
power flows in bypass, and the UPS will periodically transfer to
normal operation to charge the batteries (at 7-day intervals by UPS
default). The inverter is in stand-by and is synchronized to utility,
ready to transfer to battery operation if utility voltage is out of
tolerance. The output voltage is not regulated in this mode, but
efficiency increases. Call APC Technical Support or your nearest
APC office for more information on programming your APC BC300
Series UPS for Economy Mode.
** Stand-by ** Both static switches are open. The unit is not supplying output
voltage.
