Introduction; Safety Precautions - EnerSys Nexsys 12NXS26 Technical Manual

INTRODUCTION

Since their introduction in the early 1990s, thin plate pure lead (TPPL) blocs have been
established as a premium high performance bloc suitable for a wide range of demanding
applications. Today, the TPPL technology can be found in applications as diverse as
emergency power, avionics, medical, military and consumer equipment.
NexSys® blocs use the principles of advanced thin plate pure lead technology, to achieve
exceptionally high performance, energy density and cycling capability. These characteristics
make the NexSys range ideal for use in motive power applications such as Floor-care, Pallet
Trucks, AGV's, Personnel Carriers and Utility Vehicles.
This manual describes the NexSys bloc range, physical characteristics and the basic
information on storage operation and maintenance.

SAFETY PRECAUTIONS

Motive Power blocs for small traction Valve Regulated Lead Acid (VRLA) NexSys series:
TPPL technology.
NexSys blocs are designed using proven gas recombination technology, which removes the
need for regular water addition. The use of gas recombination technology for lead acid blocs
has completely changed the concept for motive power. This new technology gives the user
greater freedom to use valve regulated lead acid blocs in a much wide range of
applications.
The minimal level of gas emissions from this type of bloc allows the bloc to be used in
applications where previous restrictions might have been enforced. The NexSys range is
considered to be maintenance free, therefore there is no need for any routine water refilling
to be carried out on the bloc.
• Pay attention to the operating instructions and
keep them close to the bloc.
• Work on blocs must only be carried out by
skilled personnel!
• Use protective glasses and wear safety clothing
when working on blocs.
• Adhere to the current accident prevention rules in the
country where the blocs is used or DIN EN 50272-3,
DIN EN 50110-1.
• Keep children away from batteries!
• No smoking!
• Do not expose blocs to naked flames, glowing
embers or sparks, as it may cause the battery to
explode.
• Avoid sparks from cables or electrical apparatus as well
as electrostatic discharges.
• Acid splashes into the eyes or on the skin must be
washed immediately with an abundance of clean water.
After abundant flushing consult a doctor immediately!
• Clothing contaminated by acid should be washed
in water.
Warning: Do not use any type of oil, organic solvent, alcohol, detergent, strong acid, strong
alkali or petroleum based solvent or ammonia solution to clean the monoblocs. Such
materials may cause permanent damage to the monobloc casing.
• Risk of explosion and fire
• Avoid short circuits: do not use non-insulated tools, do
not place or drop metal objects on top of the battery.
Remove rings, wristwatches and articles of clothing with
metal parts that might come into contact with the battery
terminals.
• Electrolyte is highly corrosive.
• In the normal operation of this battery, contact with acid
isn't possible. If the cell containers are damaged, the
immobilised electrolyte (absorbed in the separator) is
corrosive like liquid electrolyte.
• Batteries and monoblocs are heavy. Ensure secure
installation! Use only suitable handling equipment.
• Lifting hooks must not damage the blocs, connectors or
cables.
• Do not place batteries in direct sunlight without
protection. Discharged batteries can freeze. For that
reason, always store in a frost–free zone.
• Dangerous electrical voltage!
• Avoid short circuits: NexSys batteries are capable of
high short circuit currents.
• Caution — metal parts of the batteries are always live:
do not place tools or other objects on the battery!
• Pay attention to the hazards that can be caused by
batteries.
