end cables, cable eyes or cables. First screw them in by hand, then use a torque
wrench.

The terminal covers must be assembled on to the screw heads by means of
manual pressure on the cylindrical part, then fold the black cover down on to the top
of the battery.

Safety Requirement: Place the cells or monoblocs in such a way that the
terminals or bare conductor parts having a potential difference of potential of more
than 120V cannot be touched simultaneously by accident.
YES NO

To minimise electrical risks during cabling, here is the recommended method:
a) Choose from the battery string an end cable or cable eye that is easy to
access, and that you will assemble only at the end of the cabling process
after having verified that there is no difference in potential between the 2
terminals.
b) Cable the end cables for each shelf or level.
c) Cable the most difficult to reach cable eyes for each shelf or level, mainly
at the back.
d) Cable the inter-shelf or inter-level cable eyes or cables.
e) Connect the cables to the terminal cabinet, fuses or circuit breaker, making
sure there is no difference in potential between the polarities of the cabinet.

At the end of the cabling ,
it’s important to check that no electrical potential exists
between cabinet or rack metal-framed and each polarity (+/-) of final batteries.
7-2/ CONNECTING THE BATTERY TO THE APPLICATION
The performance of the battery is measured at the level of its take-off terminals.
As a result, the length of the connections between the battery and the application
must be as short as possible, so as not to affect the efficiency of the unit as a whole.
The section of connectors must not only be chosen on the basis of its current
capacities. The section must also be chosen to minimise the potential difference
between the battery and the application. If the potential difference is too significant,
the expected autonomy of the equipment will be reduced.
