Warning

Batteries, battery posts, terminals and related accessories
contain lead and lead compounds, and other chemicals known
to the state of California to cause cancer and birth defects or
other reproductive harm. Wash hands after handling.

SAFETY PRECAUTIONS

Although all valve-regulated batteries have the elec­trolyte immobilized within the cell, the electrical hazard
associated with batteries still exists. Work performed on

these batteries should be done with the tools and the
protective equipment listed below. Valve-regulated

battery installations should be supervised by personnel
familiar with batteries and battery safety precautions.

Protective Equipment

To assure safe battery handling, installation and
maintenance, the following protection equipment
should be used:

1. Safety glasses or face shield

2. Acid-resistant gloves

3. Protective aprons and safety shoes

4. Proper lifting devices

5. Properly insulated tools

Procedures

The following safety procedures should be followed
during installation: (Always wear safety glasses or

face shield.)

1. These batteries are sealed and contain no free elec­trolyte. Under normal operating conditions, they do not

present any acid danger. However, if the battery jar or
cover is damaged, acid could be present. Sulfuric acid

is harmful to the skin and eyes. Flush affected area
with water immediately and consult a physician if
splashed in the eyes.

2. Prohibit smoking and open flames, and avoid arcing in
the immediate vicinity of the battery.

3. Do not wear metallic objects, such as jewelry, while
working on batteries.

4. Keep the top of the battery dry and clear of all tools and
other foreign objects.

5.

Provide adequate ventilation (per IEEE standard 1187 and
/or local codes) and follow recommended charging voltages

6. Extinguishing media: Class ABC extinguisher. Note:

may be used but not directly on the cells due

to thermal shock and potential cracking of cases.

7. Never remove or tamper with pressure relief valves.
Warranty void if vent valve is removed.

8. Inspect all flooring and lifting equipment for functional
adequacy.

9. Adequately secure battery modules, racks, or cabinets
to the floor.

10. Connect support structure to ground system in accor­dance with applicable codes.

RECEIVING AND STORAGE

Receiving Inspection

Upon receipt, and at the time of actual unloading, each
package should be visually inspected for any possible
damage or electrolyte leakage. If either is evident, a
more detailed inspection of the entire shipment should
be conducted and noted on the bill of lading. Record
receipt date, inspection data and notify carrier of any
damage.

Unpacking

1. Always wear eye protection.

2. Check all batteries for visible defects such as cracked
containers, loose terminal posts, or other unrepairable
problems. Batteries with these defects must be replaced.

3. Check the contents of the package against the packag­ing list. Report any missing parts or shipping damage
to your East Penn agent or East Penn Mfg. Co.
immediately.

4. Never lift batteries by the terminal posts.

5.

.

Always lift batteries by the bottom or use the lifting handles.

Storage

1. Cells should be stored indoors in a clean, level, dry and
cool location. Recommended storage temperature is 0°F
to 90°F (–18°C to 32°C).

2. Stored lead-acid batteries self discharge and must be
given a charge six months from date of manufacture
to prevent permanent performance degradation.
Record dates and conditions for all charges during
storage.

3. Recommended charge during storage is at a constant
voltage of .30 volts per battery greater than recom­mended float voltage for 24 hours. (Reference the float
voltage chart on next page.)

4. Do not store beyond 12 months.

INSTALLATIONS

General

Caution should be taken when installing batteries to
insure no damage occurs. The battery cabinet, tray,
rack, etc. shall be inspected for sharp edges that could
cause damage to the battery casing. Batteries shall not
be dropped, slid, placed on rough or uneven surfaces
such as tray lips or grated flooring. Mishandling of
batteries could result in equipment damage or human
injury. East Penn will not be liable for damage or injury
as a result of mishandling or misuse of the product.

Grounding

When grounding the battery system, proper techniques
should be applied per electrical standards, such as NEC
and/or local codes.

Cabinets

Cabinet systems come factory assembled and prewired.
Do not tip or turn cabinets on their sides when position­ing them in their intended installation area. Cabinets
must be used in an upright position. These systems
are preconnected. Only inter-shelf, inter-cabinet and
connections to the load are required. See the connection
diagram inside the cabinet. Inter-cabinet and load
connection cables are not included.

General

1. Install the lockwasher and torque the terminal bolts or
uts. (See Table 1 for correct torque values.)

n
DO NOT OVERTORQUE. Some batteries have cable

harnesses (torque value is 45 ± 5).

. After torquing the connections on racked batteries, read

2

the voltage of the battery string to assure that individual
batteries are connected correctly. The total voltage should
be approximately equal to the number of batteries times
the measured voltage of one battery (when connected in
series). If the measurement is less, recheck the connections
for proper voltage and polarity.

3. Read and record intercell connection resistance and

note the method of measurement. This helps determine
a satisfactory initial installation and can be used as a
reference for future maintenance requirements. See

Appendix A, recording forms, in the back of the manual.
Clean, remake and remeasure any connection having
a resistance measurement greater than 10% of the
average of all the same type of connections (inter­cell, inter-tier or shelf, inter-rack or inter-cabinet).

4. Battery performance is based on the output at the battery

terminals. Therefore, the shortest electrical connections
between the battery system and the operating equipment
results in maximum total system performance.

Do not select cable size on current carrying
capability only. Cable size should not provide a greater

voltage drop between the battery system and operating
equipment than specified. Excess voltage drop will
reduce the desired support time of the battery system.

See rack assembly instructions.

BATTERY ASSEMBLY

(Always wear eye protection.)

1. Set up the batteries so that the positive post (+) of one
battery is connected to the negative post (–) of the next
battery for all series connections.

2. The intercell connector contact surfaces shall be cleaned
by rubbing gently with a non-metallic brush or pad before
installing connectors. No-ox-ID grease can be used but
is not required.

3. Install all intercell connectors loosely to allow for final
alignment of batteries, then torque. (See Table 1 for

correct torque/retorque values.)
