CAUTION
Read this document before you start to operate or perform work on the UPS
system.
This document contains important instructions that must be followed during the
installation, operation and maintenance of the accessory cabinets. Read all of
the instructions before operating the equipment. Keep this manual for future
reference.
In this manual, the term UPS refers only to the UPS cabinet and its internal
elements. The term UPS system refers to the entire power protection system –
the UPS cabinet, the battery cabinet, and options or accessories installed.
The accessory cabinets contain components that carry high currents and
voltage. A properly installed enclosure is earthed and IP23 rated against
electrical shock, foreign objects and water. The accessory cabinets are parts of
sophisticated power systems and only qualified personnel are allowed to install
and service them.
DANGER
The accessory cabinets carry lethal voltages. All repairs and service must be
performed by authorized personnel only. There are no user-serviceable parts
inside the cabinets.

Do not move the battery cabinets with batteries inside if the sheet plates are
not installed.
Before you start any installation or service work, make sure that all AC and
DC power sources are disconnected. Power may come from multiple sources.
Also ensure system grounding / protective bonding continuity.
In a parallel system, the output terminals may be energized even when the
UPS is turned off.
Batteries can present a risk of electrical shock or burn from high short-circuit
current.
Electric energy hazard. Do not attempt to alter any battery wiring or
connectors. Attempting to alter wiring can cause injury.
Do not open or mutilate batteries. Released electrolyte may be toxic and is
harmful to the skin and eyes.
IMPORTANT: The battery may consist of multiple parallel strings. Make sure
that you disconnect all strings before installation.
CAUTION
Only qualified service personnel knowledgeable of batteries and the required
precautions are allowed to perform installation or service work on batteries.
Keep unauthorized personnel away from the batteries. Before you install or
replace batteries, consider all the warnings, cautions, and notes concerning
appropriate handling. Do not disconnect the batteries when the UPS is in the
Battery mode.
Make sure that your replacement batteries are of the same number and type
as the battery that was originally installed.
Before you connect or disconnect battery terminals, disconnect the charging
source by opening the corresponding battery circuit breaker.
Check if the battery is inadvertently grounded. If it is, remove the source of
the ground. Contacting any part of a grounded battery can cause a risk of
electric shock. If you disconnect the grounding connection before you work on
the batteries, the risk of an electric shock is less likely.
Dispose of batteries according to your local disposal requirements.
Do not dispose of batteries in a fire. When exposed to flame, batteries may
explode.
To ensure proper cooling airflow and to protect personnel from dangerous
voltages inside the unit, keep the UPS door closed and the front panels
installed.

3.1 Introduction to EBC-F and EBC-G
The Eaton external battery cabinets provide emergency short-term backup
power to safeguard operation during brownouts, blackouts, and other power
interruptions. The battery cabinets line-up and match with the Eaton UPS
product line, and should only be used in an Eaton UPS system. This manual
gives instructions on the use and installation of two battery cabinets: EBC-F and
EBC-G.
The EBC-F is designed to be used with an uninterruptible power supply (UPS)
that is rated up to 100 kW output power. The EBC-F has one battery string that
has 36 or 40 battery blocks.
The EBC-G is designed to be used with an uninterruptible power supply (UPS)
that is rated up to 200 kW output power. The EBC-G has one battery string that
has 36 or 40 battery blocks.
Control wiring for both EBC-F and EBC-G is supplied with the cabinet. The
battery cabinet can be located anywhere near the UPS cabinet, if you run the
Battery-to-UPS power wiring outside the cabinets. However, the recommended
way to install the cables is through the left side panel of the battery cabinet, with
the battery cabinet located next to the 9PHD UPS on its right side.
There are several cable entries in the battery cabinets. The cabinets can be
wired in the following ways.

• through the left side panel
• through the right side panel
• through the back panel
• through the bottom panel
By default, Eaton UPSs and battery cabinets should only be used with valve-
regulated lead-acid (VRLA) batteries. For the battery specification of your UPS,
see the User’s and Installation Guide of your UPS. Only use batteries that have
been approved by Eaton. If you have to connect other type of batteries or other
energy storage means, consult an authorized Eaton Customer Service Engineer
before you proceed with the installation.
The battery block configuration in the chosen battery cabinet must always match
the UPS requirement. The used battery configuration must be entered into the
UPS settings during commissioning or start-up. Refer to the UPS User’s and
Installation Guide for the UPS configuration.
Both battery cabinets have a temperature sensor (Harness 9PHD EBC
temperature sensor, P-152001325).

3.3 Introduction to 9PHD transformer cabinet
The 9PHD external transformer cabinet (TFC-A) can house one or two
transformers for the UPS system. You can use either isolation transformers or
autotransformers.
You can use the transformers for the UPS input line (a single feed that supplies
both rectifier and bypass inputs), rectifier input line, bypass input line or output
lines. Typically the transformer cabinet is used for input and output, or input and
bypass lines.
