3.1. Assembly into batteries
The electrical connection in series
of monoblocks will be made
according to the space available
and to minimize the length of the
cables or rigid connections.
The connection of the hydraulic
system to each of the monoblocks
will follow a path parallel to the
electrical circuit so that there is
no potential difference between
the two ends of a connecting
pipe. The direction of the water
or gas flow is not important.
The maximum number of
monoblocks connected in hydraulic
series is limited to 10 on a single
circuit, which is equivalent to
50 cells. For larger battery units,
several totally independent circuits
must be provided (for details see
chapter 3.3.).
During the installation into
batteries, the monoblocks must
not be able to move in any three
directions depending on the
mechanical constraints.
The monoblock STM 5-140 MR’s
are being shipped with belt plates.
The monoblock STM 5-100 MR and
STM 5-100 MRE’s have built-in belt
plates to prevent a swelling.
The plates of the monoblock
STM 5-140 MR’s can be
removed, under condition that
the battery structure provides
sufficient protection against
deformation of their small sides.
Only the small sides of the
blocks must be braced in case
of connection of rows of
several monoblocks.
In practice, the monoblock
STM 5-140 MR’s will be set up
in rows on the axis of the small
sides, without any gap but with
a shim plate between the
monoblocks. The consolidated
bracing system must withstand
an expansion force of 150 daN
per row.
Liquid-cooled STM 5-100 MRE
monoblocks do not require free
vertical space on any side.
By contrast, it is important to
leave space between the large
sides of the STM 5-100 MR and
STM 5-140 MR monoblocks in
order to ensure the collective
cooling through air circulation.
The ventilation space between
rows must be between 10 and
20 mm (refer chapter 3.2.).

3. Installation
An installation according to
the following, and perhaps
more specific, instructions is
imperative to ensure the
longevity and performance of
the battery as well as its
operational safety. Specifically,
the installation and assembly of
the monoblocks into batteries,
their hydraulic connection, and
the installation of the ventilation
and cooling systems must be
done with great care.
For the final installation that will
be specific to every vehicle,
this manual only provides
general guidelines.
All battery installations must
be approved by Saft.
