Introduction

Valve regulated lead acid (VRLA), Thin Plate Pure Lead (TPPL)
NexSys CORE batteries
®
(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
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
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
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
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
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.

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

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
use in 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.
