Mounting
5.1
Preparing for installation
The cells are charged and delivered ready for use.
Before assembly please conduct the
following testing and preparation steps:
5.1.1
Check that no damage has occurred during delivery and make sure that no damage was
caused during transportation.
5.1.2
Check the open-circuit voltage (OCV) of the cells. A cell voltage below 2.10 V, indicates a
bad state of charge of the cells. Make sure that the batteries are charged under constant
load 72h before (or just after) the installation. A cell voltage below 2.02 V indicates
irreversible damage likely caused during transport and storage, and a check or
replacement of the affected unit is recommended.
For cleaning the batteries please note the instructions under:

Installation works
Take note of the contents of this manual prior to
installation
and record them for
later consultations.
During mounting, follow the instructions below:
5.2.1 The insertion of the battery tray is carried out in accordance with the instructions of the
vehicle manufacturer and any internal instructions of the railway operator. The work must
be performed by trained personnel.
5.2.2 Due to the heavy weight of lead-acid batteries a suitable mechanical lifting truck or crane
for handling must be used.
5.2.3
Do not use grease on the frame rails or the end terminals. If a protective grease is
necessary for the connections, use
only
pure silicone grease
(risk of damage to plastic
cases).
5.2.4
The installation in non-ventilated sealed housing is not permitted
. Verify during
installation that the battery compartment of the train allows sufficient air exchange.
5.2.5 During installation (and later operation) of their moving stationary battery system is
essential to comply with the applicable regulations. In particular, we refer to:
EN 62485-2 : 2019
«Safety requirements for secondary batteries and battery
installations»
Local regulations for Low Voltage Installation.
5.2.6 Open and secure the switch of the electrical installation to the battery box, so for the
assembly the battery lines to the charging rectifier and the loads are fully isolated and the
battery voltage is “floating”.
5.2.7 Also a battery disconnected from the charger or the external circuit supplies
live
electrical voltage
and small quantities of Oxyhydrogen gas can escape. Prevent open
flames, electrostatic discharges, sparks and short circuits with clothing, jewellery,
watches and tools during the installation.
5.2.8 Verify that during operation
sufficient air circulation will ensure the dissipation of
heat out of the compartment.
Check that any ventilation filters are not blocked.
