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.

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.

3.3 Installing the Maintenance Bypass Panel and UPS

IMPORTANT!

If you do not have an APC Maintenance Bypass Panel, you must provide overcurrent protection
and a UPS input AC disconnect means.
APC strongly recommends that a means of bypassing the UPS from the critical load be
provided for maintenance.

Follow these guidelines when installing the Maintenance Bypass Panel and UPS:

• Install the Maintenance Bypass Panel within sight of the UPS. When installing the
Maintenance Bypass Panel, see illustrations under
any instructions provided with the Maintenance Bypass Panel.

• Install all wiring in accordance with applicable electrical codes. Use 75° C copper
conductors.

• Install the AC input and UPS output in separate conduits. UPS output circuits

must be installed in dedicated conduit systems and separate from other

electrical circuits.

• Control wiring must be installed in a separate conduit.

• Good ground connections are necessary to reduce electrical noise and make the
operation of the UPS and the loads safe. Follow the grounding guidelines in the
installation wiring diagram. Refer to the National Electrical Code (NEC),
appropriate IEEE documents, and all applicable codes.

• For systems with non-linear, neutral-connected loads, standard practice is to size the
neutral conductor for 1.732 times the phase current.

• When installing the AC wiring, refer to the illustration

BC300

and to any additional diagrams provided with the UPS. The illustration

shows typical installations . Your installation may be different.

3.5.6 Product Specifications

3.5.6.1 Monitoring Port Pin Assignments

The Monitoring port is a 9-pin communications port. The port operates with no flow control at
a rate of 2400 baud. The data format is 8 data bits with 1 start bit, 1 stop bit, and no parity.
When the Triple Chassis operates with simple signalling, the following limitations and
capabilities apply to the Monitoring port:

• Pins 3, 5, and 6 are open collector outputs which must be pulled up to a common
referenced supply no greater than +40 VDC. The transistors are capable of a non­inductive load of 25 mA. Use only Pin 4 as the common.

• The output at Pin 2 generates a low-to-high RS-232 level when the device is
signalling an On Battery condition. The pin is normally at a low RS-232 level.

• The UPS is signalled to shut down when a high RS-232 level is applied to Pin 1 for

4.5 seconds. Shutdown is also dependent on the UPS status.

When the Triple Chassis operates with advanced signaling, the following limitations and
capabilities apply to the Monitoring port:

• Pin 7 is unassigned.

• DC operating voltage is available on Pin 8. This voltage may be from the UPS or from

an external adapter.

3.6 Installation of External Batteries and Battery Breaker

Some units are connected to optional external batteries in a separate cabinet or rack.
External batteries must be installed and connected to the UPS by an authorized service person
familiar with UPS battery installations and applicable building and electrical codes.

3.6.1 Battery Installation

WARNING

Full voltage and current are always present at the battery terminals. The batteries used in this
system can produce dangerous voltages, extremely high currents, and may cause a risk of
electric shock. They may cause severe injury if the terminals are shorted together or to ground
(earth). You must be extremely careful to avoid electric shock and burns caused by contacting
battery terminals or shorting terminals during battery installation. Do not touch uninsulated
battery terminals.
Only authorized service personnel familiar with battery systems and required precautions may
install and service the batteries. The installation must conform to national and local codes. Keep
unauthorized personnel away from batteries.

30 Installation Guide APC BC300 Series 10kW 208/450/480V UPS

Installation

CAUTION!

The qualified service person must take these precautions:

1. Wear protective clothing, such as rubber gloves and boots and protective eye wear. Batteries
contain caustic acids and toxic materials and can rupture or leak if mistreated. Remove rings,
metal wristwatches, other metal objects and jewellery. Do not carry metal objects in your
pockets where the objects can fall into the battery cabinet.

2. Tools must have insulated handles and must be insulated so that they will not short battery
terminals. Do not allow a tool to short between individual or separate battery terminals or to
the cabinet or rack. Do not lay tools or metal parts on top of the batteries, and do not lay them
where they could fall onto the batteries or into the cabinet.

3. Install the batteries as shown on the drawing provided with the batteries. When connecting
cables, never allow a cable to short across a battery’s terminals, the string of batteries, or to
the cabinet or rack.

4. Align the cables on the battery terminals so that the cable lug will not contact any part of the
cabinet or rack, even if the battery is moved. Keep the cable away from any sharp metal
edges.

5. Install the battery cables so they cannot be pinched be the UPS or battery cabinet doors.

6. Do not connect the battery terminal to ground (earth). If any battery terminal is inadvertently
grounded, remove the source of the ground. Contacting any part of a grounded battery can
cause a risk of electric shock.

7. To reduce the risk of fire or electric shock, install the batteries in a temperature and humidity
controlled indoor area, free of conductive contaminants.

8. Battery system chassis ground (earth) must be connected to the UPS chassis ground (earth).
If you use conduit, this ground conductor must be routed in the same conduit as the battery
conductors.

9. Where conductors may be exposed to physical damage, protect the conductors in accordance
with all applicable codes.

10. If you are replacing batteries or repairing battery connections, shut off the UPS and remove
both AC and DC power.

Battery Installation Guidelines:

• Refer to any instructions provided with the batteries, battery breaker and pre-charge
/discharge switch.

• External batteries require a fused disconnect or a DC battery breaker. There should
be a disconnecting means for each battery string. The external battery fuse protects
the battery cables. Size the cables based on the overcurrent protection device.

• The battery cables must be sized for a total maximum voltage drop of 2.0 VDC at the
rated DC current.

• Wherever conductors may be exposed to physical damage, protect the conductors in
accordance with any applicable codes. This includes battery cables between the UPS
and the battery system and cables between battery cabinets or racks.

• APC recommends the routing of battery cables through flexible conduits. Install
flexible conduits for battery cables according to local or national codes.

• The battery system ground (earth) must be connected to the UPS chassis ground
(earth). This ground conductor must be routed with the battery cables.

3.6.2 Battery Replacement

Only authorized service personnel familiar with battery systems may replace batteries. See the
“Start-up & Shutdown Procedure” section in this Installation Guide to bypass and shut down
the UPS.

CAUTION!

Study all warnings at the beginning of this section before replacing the batteries.

• Use the Same Number and Type of Battery: To ensure a well-functioning UPS
and to maintain proper battery charger operation, you must replace a given number
of batteries with the same number of batteries. The batteries must be the same
manufacturer type as the original batteries and have the same voltage and ampere­hour rating as the original batteries.

• Verify that the Battery Terminal is not Grounded: If any battery terminal is
inadvertently grounded, you must remove the connection from the terminal to
ground (earth) before you service the batteries. Contacting any part of a grounded
battery can cause a risk of electric shock. To reduce the risk of electric shocks,
disconnect the ground connection before you service the batteries.

• Handle Used Batteries with Care: Assume that old batteries are fully charged.
Use the same precautions you would use when handling a new battery. Do not short
battery terminals or the battery string with a cable or tool when you disconnect the
batteries.

• Dispose of Batteries Properly: Do not dispose of batteries in a fire as the batteries
may explode. Do not open or mutilate batteries. Released electrolyte is harmful to
the skin and eyes and may be toxic. Batteries contain lead. Many state and local
governments have regulations about disposing of used batteries. For assistance, call
APC Technical Support or call your local APC office.
