3. Labelling and area of application
These instructions for use applies for cells in accordance
with EC Type Examination Certificate and IECEx Certificate of
Conformity Number:
IECEx SIR07.0061U - SIRA 01ATEX3016U Type B Lead Acid
Motive Power cells (PzB, PzMB)
IECEx SIR07.0062U - SIRA 01ATEX3019U Type D Lead Acid
Motive Power cells (PzS, PzM)
IECEx SIR07.0063U - SIRA 03ATEX3087U Type B Evolution
Lead Acid Motive Power cells (PzVB)
IECEx SIR07.0064U - SIRA 03ATEX3090U Type D Evolution
Lead Acid Motive Power cells (PzV) and NexSys cells (NxS)
The U character behind the certificate number indicates that
this certificate must not be mistaken for a certificate intended
for a device or protective system. This component certificate
may only be used as the basis for the certification of a device
or
protective
system.
The
only refer to the conception and type testing of the specified
component cells in compliance with Directive 2014/34/EU. To
produce and circulate the cells, the manufacturer must fulfil
other requirements of the Directive, which are not covered by
these certificates.
This gives rise to the necessity that a final installation
operation must have fulfilled the requirements as an ATEX
and/or IECEx-certified business and able persons.

These Ex cells may be used in the following areas only:
•
Explosion group I Category M2/Mb mining
•
Explosion group II Category 2 and 3
[Zone 1 2G/Gb, Zone 2 3G/Gc (Gas)]
•
Explosion group III Category 2 and 3
[Zone 21 D/Db, Zone 22 3D/Dc (Dust)]
4. Assembly
When mounting, the cells must be always lifted by all posts
simultaneously with insulated hanging equipment.
Ex cells may only be connected in a row (serial connection). No
parallel connection is allowed. During mounting, the correct
polarity must be observed. For the electrical wiring, only
components authorised by EnerSys
aquamatic system and electrolyte circulation must be wired
in accordance with EnerSys requirements, e.g. "comply with
the electrical wiring". Request corresponding information, if
required.
Note:
The
connection
technology,
electrolyte circulation are part of the cell component test and
approval and must therefore not be modified!
All components should be obtained from EnerSys.
End connections and intermediate take-offs may also only be
carried out with approved components. New, unused screws
M 10 x 20 with the prescribed screw lock must be used.
Torque 25 + 2 Nm! It is absolutely mandatory to ensure correct
contacting and thread engagement.
The connections must be tightened to the lid. To ensure the IP
protection, a lid without any holes must be used.
When using connector caps with a hole (only on the nega tive
pole for voltage measurement), the connector chamber must
be filled with grease such as Berutox M 21 KN.
Electronic components cannot be used in the vicinity of an
ATEX/IECEx battery such as under any lid or close to the cell.
Only Ex cells of the same type, size and capacity may be wired
together.
The Ex cells must be installed firmly in the battery container.
Any possible clearances must be filled with stable acidproof
certificates

filling material. The use of cell boxes or foam-like filling
material is not permissible.
5. Commissioning

com).
In addition, the instruction for use of the device or protective
system, in which these Ex cells are integrated, applies.
Lead-acid cells, in particular flooded cells, can only be stored
for a limited period of time without regular recharging. New
cells should be fully charged on delivery. Hawker Perfect Plus
and Water Less cells must be recharged every 6 weeks at the
latest, Hawker Evolution and NxS cells should be recharged
within 3 months.
When reassembling batteries, only cells of the same state of
charge and cells which are ATEX labelled should be wired
together. The open-circuit voltage of the cells should be at
least 2.13 V / cell in a fully charged condition.
6. Operation and charging
Never charge an Ex battery or cells in a zoned area at any time.
For charging and operation, the instructions for use of the
normal battery design can be used (see www.enersys.com). In
addition, the instructions for use of the device or protective
system, in which these Ex cells are integrated, applies.

devices in the vehicle and when charging the batteries in
areas at risk of explosion, it is mandatory that the charging
system is integrated in the compliance assessment according
EN 60079-7.
Batteries that have reached a higher temperature than 40°C by
the end of charging must be cooled down to 40°C before use
and
in areas at risk of explosion.
7. Maintenance and repairs
Only approved EnerSys original spare parts and components
may be used. Only cells, which carried an ATEX label of a
manufacturer with the same type, size and capacity may be
used as a replacement.
In addition, the instruction for use of the device or protective
system, in which these ex cells are integrated, applies.
To conduct this work, the rules of EN 60079-19 must be
observed. The rework must only be carried out by "suitably
qualified personnel" and must be documented and the device
or protective system must be identified with a corresponding
R label.
