Instruction Manual NexSys
Introduction
Valve regulated lead acid (VRLA), Thin Plate Pure Lead (TPPL)
NexSys CORE batteries are certified to ATEX standards
®
(increased safety concept Ex e) for use in hazardous areas
where there is a risk of explosion, due to gas or dust. These
batteries are part of the following equipment groups and
categories:
• Group I, category M2/Mb
• Group II, categories 2 and 3 (Zone 1 2G/Gb, Zone 2 3G/Gc)
• Group III, categories 2 and 3 (Zone 21 2D/Db and Zone 22
3D/Dc)
Relative to conventional ATEX batteries, the patented
ventilation design of EnerSys battery trays may make it
possible for a higher capacity battery to be selected for a given
truck manufacturer's available battery compartment.
Unlike conventional batteries
NexSys CORE ATEX batteries are valve-regulated lead-acid
®
batteries with immobilised electrolyte. Instead of a vent plug, a
valve is used to regulate the internal gas pressure, preventing
the ingress of oxygen from the air and allowing the escape of
excess charging gasses.
Operating VRLA batteries require similar safety precautions
as vented batteries, specifically there are risks associated
with electrical, corrosive and explosive hazards. Battery
valves must never be removed. These batteries do not require
topping up with distilled or demineralised water.
This manual should be used in conjunction with the manual
for standard NexSys CORE batteries which is available on
®
www.enersys.com.
Upon receipt, batteries should be in perfect condition and free
from any damage. If any damage is noted or accessories are
missing, please contact your supplier immediately.
ATEX-certified NexSys batteries are designed for use in
battery-powered applications (such as electric counterbalance,
reach and pallet trucks) within hazardous areas. EnerSys cells
and connectors have an IP (ingress protection) of 65; creates
of 23 (when lids fitted).
The use of electrical equipment, such as DC-DC convertors,
low voltage alarms and EnerSys' Wi-iQ units, is prohibited
unless certified for use in hazardous areas and fitted outside
the battery.
Conformity
NexSys CORE ATEX batteries conform with the relevant
®
provision of ATEX Directive 2014/34/EU.
Conformity has been demonstrated with reference to the
following documentation:
ATEX IECEx
SIRA 01ATEX3022X SIRA IECEx 07.0065X
SIRA 03ATEX3090U SIRA IECEx 07.0064U
Notes
:
• ATEX certificates apply to the EU whilst IECEx certificates relate to the
rest of the world (except North America).
• Quality assurance notification: SIRA 01 ATEX M103.

Description
Batteries up to
68.8 kWh
DIN-size NexSys
(and Gel) cells
The applicable rating data for NexSys
as follows:
1. Nominal capacity C :
5
2. Nominal voltage:
3. Discharge current:
4. Rated temperature:
These cells comply with the following clauses:
EN/IEC 60079-0 clause 23.3 (Cell types), 23.6 (Interchangeability),
23.8 (Leakage)' 23.9 (Connections), 23.10 (Orientation) and 23.11
(Replacement of cells or batteries), and EN/IEC 60079-7 clause
5.6 (classification), 5.6.3.1 (Types of permissible batteries),
5.6.3.3 (cells), 5.6.3.4 (connections) and 6.6.3 (shock test).
When they are assembled into a battery, the remaining
clauses of EN/IEC 60079-7 need to be addressed with
particular reference to clauses EN/IEC 60079-0 clause 23.2
(Batteries), 23.4 (Cells in a battery), 23.5 (Rating of a battery),
23.11(Replacement of cells or batteries), and EN/IEC 60079-7
clause 5.6.3.2 (Battery containers), 5.6.4 (Charging of cells and
batteries), 6.6.2 (insulation resistance) and 6.6.4 (ventilation).
The cells covered by this certificate shall be installed in series,
in a suitable battery enclosure, together with cells of the same
electrochemical system, cell design and rated capacitance
that is manufactured by EnerSys. The battery enclosure shall
provide protection from mechanical impact;
The cells shall be installed in a vertical orientation, with the
electrical connectors at the top.
This equipment includes non-conducting parts that may
generate an ignition-capable level of electrostatic charges
under certain extreme conditions. The user shall ensure that
the equipment is not installed in a location where it may be
subjected to external conditions (such as high-pressure steam)
which might cause a build-up of electrostatic charges on non-
conducting surfaces. Additionally, cleaning of the equipment
shall be done only with a damp cloth;
The cells shall have a certified service temperature range of
-20°C to +60°C, which shall be taken into account when used in
a battery. Battery operating conditions take precedence.
