3. SAFETY PRECAUTIONS
Before installing or maintaining this system, it is extremely important to read this
manual and be sure that all system drawings and schematics are reviewed and
clearly understood. If there are any questions concerning this manual or any of the
installation or maintenance procedures and/or requirements please contact a C&C
Power representative before proceeding.
When installing this power system, follow all applicable federal, state and local
regulations as well as industry guidelines to insure proper system installation.
Only qualified electricians or DC power technicians should attempt to install or
service this equipment.
System installation and maintenance should always be performed with heavily
insulated tools. It is also recommended to wear rubber gloves, boots, and use
insulating mats to stand on when working on this equipment.
Always wear eye protection when installing or maintaining batteries and/or power
equipment.
Battery cabinet systems are extremely heavy. Use a minimum of two people when
unloading and setting equipment in place.
Do not smoke or present open flames near any battery system.
For the safety of others, never leave an open cabinet or panel unattended.
To reduce the risk of fire, replace fuses with the same type and rating of fuses
supplied with the system.
DC Power and Batteries can be very dangerous and have extremely high short
circuit current. Electrical shock, severe burns, fire or death can result from a system
short.

5. SYSTEM OVERVIEW
During normal operating conditions the UPS supplies power to the load as well as the necessary
power required to keep the batteries at the proper float voltage. When AC power fails, the
batteries will discharge in order to provide the necessary backup power to the load. It is the
responsibility of the customer to make sure the batteries are not discharged below manufactures
recommendations. After any battery discharge has occurred, the batteries should be recharged as
soon as possible. Batteries will be damaged if not properly recharged right away. See the UPS
manual for more information on charging the batteries.

7.2 INSTALLATION STEPS
7.2.1 EQUIPMENT LOCATION
Prior to installation, verify floor loading requirements and all applicable codes pertaining to the
related equipment. Environmental conditions should also be reviewed. Battery systems require
an area with proper ventilation and cooling. An ambient temperature between 20°C to 25°C
(68°F to 77°F) is recommended for optimum battery life and performance. The cabinet has vent
holes located at the front and rear of the system. Never install the cabinet into a sealed
enclosure. Clearance around the equipment should be as suggested by NEC and/or all applicable
national and local codes.
7.2.2 EQUIPMENT MOUNTING
1. The BC11 is equipped with four casters, two swivel type casters in the front and two rigid
type casters in the rear. Roll the cabinet off of the skid with the provided ramp and move
the cabinet into the desired location.
2. On the floor in the desired location, mark the location of the 6 mount holes located on the
mounting brackets provided.
3. Move the cabinet out of the way and drill holes for the recommended hardware.
4. Move the cabinet back into place, align holes, and tighten hardware.
5. Should any drilling be performed on this equipment, make sure all exposed batteries and
connections are completely covered using insulated type mats.
7.2.3 EQUIPMENT GROUNDING
Terminate a cabinet ground wire from the main building ground source to the supplied #6-
300MCM mechanical lug located on the breaker pan. See section 6.2 for sizing recommendations.
Wire should be sized per NEC and/or all applicable national and local codes.
Before installing or maintaining this system, it is extremely important to read this
manual and be sure that all system drawings and schematics are reviewed and
clearly understood. If there are any questions concerning this manual or any of the
installation or maintenance procedures and/or requirements please contact a C&C
Power representative before proceeding.
Under certain conditions, batteries can vent potentially explosive gas (hydrogen).
Never enclose batteries or battery cabinets in a sealed room.
Battery cabinet systems are extremely heavy. Use a minimum of two people when
unloading and setting equipment in place.
All system ground wires should be derived from the main building ground source.
For multi cabinet systems, each cabinet needs to have a designated cabinet ground
wire derived from the main building ground source.

7.2.4 DC CONNECTIONS
1. Open the front door on the cabinet and check for any noticeable problems or damage that
may have occurred during shipment.
2. Review the attached installation drawing and schematic. A cable has been left off in the
middle of the battery string for safety and will be installed later.
3. Check and re-torque internal battery connections, as shipping may have caused these
connections to come loose. Proper torque values are noted on the drawing and also on the
battery case.
4. Connect main cables from the UPS or charger source to the battery cabinet output. The
battery cabinet output connection point will vary depending on the cabinet configuration.
The main output connection point may be directly to the circuit breaker, to the fuse block,
or to a terminal block or bus bars. Review the supplied cabinet drawing for information on
the battery cabinet output. All cables should be sized per NEC and any other local codes
pertaining to this equipment. Refer to the UPS or charger manual for wiring external
batteries. Note: Make sure charging source is disconnected before making these
connections.
5. Connect the cable that was left off during shipment and install as shown on the drawing.
Torque connections properly.
7.2.5 SYSTEM OPERATION
Please refer to the UPS system manual for system start up and operation information.
Review the attached system drawings and schematics for model specific
information on DC output connections.
Wire should be sized for a maximum voltage drop of 0.5 volt.
Battery cabinets that are not supplied with an incorporated DC output disconnect
device must have an appropriate disconnect device provided external to the cabinet.
Verify that the output breaker is in the off/open position before making any DC
connections to additional cabinets or to the UPS. Also verify that the UPS charger
is not running.

8.SYSTEM MAINTENANCE
8.1 BATTERY REPLACEMENT
1. Prepare the new battery for installation. Verify that the battery is the same type and amp-
hour rating as the batteries that are in the system.
2. Using a digital voltmeter, measure the battery voltage to verify that it is 12.4 VDC or above.
3. Use a brass wire brush or abrasive pad to polish the battery terminals.
4. Apply no-ox type terminal grease to the battery terminals to avoid corrosion.
5. Disconnect the UPS from the battery string by turning off/opening the circuit breaker in the
battery cabinet.
6. Remove the center jumper on the battery string to reduce the voltage. If replacing all
batteries, continue reducing the voltage by removing the inter-shelf jumpers.
7. Disconnect the cables from the battery to be replaced.
8. Remove the bad battery. Depending on battery location, it may be necessary to remove
additional batteries to safely gain access to the bad battery.
9. Put the new battery into place. Make sure new battery is installed properly regarding
polarity orientation. Use the supplied wiring drawing found inside the battery cabinet door
to verify the cabinet wiring.
10. Reconnect the cables to battery and make sure the connections are properly torqued.
Before proceeding with system maintenance, be sure to review and understand all
of the SAFETY PRECAUTIONS in this manual!
Verify that the output breaker is in the off/open position before servicing the
system.
When batteries are replaced they must be properly installed paying special attention
to terminal polarity orientation! If wired incorrectly it will cause a short in the
system and can result in electrical shock, severe burns, fire and possible death! Be
sure to review the system schematics before terminating any battery cables.
Caution: Risk of explosion if batteries are replaced by an incorrect type.
Do not dispose of batteries in a fire. The batteries may explode. Contact your local
hazardous waste or recycling center for battery disposal requirements.
Do not discard batteries in the trash. This product contains sealed lead acid
batteries. Contact your local hazardous waste or recycling center for battery
disposal requirements.
