IMPORTANT

Please read this manual immediately on receipt of battery before
unpacking and installing. Failure to comply with these instructions will
render any warranties null and void.

CARE FOR YOUR SAFETY

Handling

DataSafe HX batteries are supplied in a fully
charged state and must be unpacked carefully to
avoid very high short-circuit currents between
terminals of opposite polarity. Use care when
handling and moving batteries. Appropriate lifting
equipment must be used.

Keep flames away

In case of accidental overcharge, a flammable
gas can leak off the safety vent.

Discharge any possible static electricity from
clothes by touching an earth connected part.

Tools

Use tools with insulated handles.
Do not place or drop metal objects on the battery.
Remove rings, wristwatch and articles of clothing

with metal parts that may come into contact with
the battery terminals.

Dispose at registered
waste handling
facility

RECEIVING THE SHIPMENT

Carefully examine the battery shipment upon arrival for any signs of transit
damage and that it agrees with the materials list or packing slip. Be very
careful not to inadvertently discard any accessories contained in the
packing material.

Batteries contain sulfuric acid in glass fiber separators.

Use rubber gloves when handling broken or damaged containers in case of
acid leakage.

STORAGE

Store DataSafe HX batteries in a dry, clean and preferably cool location.

Since the batteries are supplied charged, storage time is limited. In order to
easily charge the batteries after prolonged storage, it is advised not to store
it more than:

6 months at ambient temperature no warmer than 77°F, (25°C)

4 months at 86°F, (30°C)

2 months at 104°F, (40°C)

Give the battery a freshening charge before the end of the recommended
storage interval.

A refreshing charge shall be performed at 2.26 V/cell at 77°F (25°C) for
96 hours or until the charge current does not vary for a 3 hour period.

The necessity of a charge can also be determined by measuring the open
circuit voltage of a stored battery.

Charge is advised if the voltage drops below 2.07 V/cell.

Maximum total storage prior to installation is 2 years from date of shipment
from factory to the customer. Freshening charges are required before the
end of the storage time period or more frequently, as noted above.

Failure to observe these conditions may result in greatly reduced capacity
and service life.

FAILURE TO CHARGE AS NOTED VOIDS THE BATTERY’S WARRANTY.

INSTALLATION

Install in clean, dry area. DataSafe HX product releases minimal amounts of
gas during normal operation (gas recombination efficiency ≥ 95%). It can be
installed near the main equipment. Batteries must be installed in
accordance with local, state and federal regulations and manufacturers
instructions.

Temperature

Avoid placing the battery in areas of high temperature or in direct sunlight.
The battery will give the best performance and service life when working at
a temperature between 68°F (20°C) and 77°F (25°C). The usual operating
temperature is between -14°F (-10°C) and 113°F (+45°C). Limits are
comprised between -86°F (-30°C) and 113°F (+45°C).

Ventilation

Under normal conditions gas release is very low and natural ventilation is
sufficient for cooling purposes and inadvertent overcharge, enabling
DataSafe HX batteries to be used safely in offices and with main equipment.

However care must be taken to ensure adequate ventilation when placed in
cabinets. Batteries must not be placed in sealed cabinets.

Security

All installation and ventilation must comply with the current local, state and
federal regulations.

Mounting

EnerSys battery racks or cabinets are recommended for proper installation.

Assemble the rack according to instructions. Place the battery blocs or cells
on the rack and arrange the positive and the negative terminals for
connection according to the wiring diagram. Check that all contact surfaces
are clean and apply the bloc or cell connectors and the terminal screws.

Tighten the screws securely. Follow the polarity to avoid short circuiting of
cell groups. Finally connect the battery terminals. It is important that the
battery is mounted firmly.

No smoking, no naked flames,
no sparks

Electrolyte is corrosive

Clean all acid splash in eyes or on
skin with plenty of clean water.
Then seek medical help. Acid on
clothing is to be washed with water.

Danger

Risk of explosion or fire. Avoid any
short circuit. Metallic parts under
voltage on the battery, do not place
tools or items on top of the battery.

Other safety precautions that need to be taken

Battery must be
recycled

Protect eyes
from electrolyte
