4 Mounting and installation
For trouble-free operation and a long product life, certain requirements for mounting and
installation must be taken into account.
4.1 Before mounting
An HV Breakout Module is equipped with two
GORE™ membranes (Fig. 4-1). These are needed
to regulate pressure and humidity. To ensure
fault-free operation of the device, never block,
clog, or insert anything into the ventilation
openings in the front side
①
and the cover of
the housing
②
. If this happens, condensate
will accumulate inside the housing and
damage the measurement module.
➁

NOTE!
i
The GORE™ membranes are needed to regulate pressure and humidity.
"
Do not block the ventilation opening for the GORE™ membranes during
installation.
NOTE!
i
Trouble-free operation and electrical safety can only be ensured if the
measurement module is correctly installed.
"
Ensure correct installation.
"
Operate the measurement module exclusively within the specified
operating environment.
→ See HV BM datasheets for further information.
4.2 Mounting HV Breakout Module
CAUTION!
HV Breakout Modules can heat up very considerably when current flows
through them. This applies not only during operation, but also when no
measurements are to be taken, but the module is integrated in a loaded
circuit (e.g. when charging the vehicle battery).
"
Divert the resulting power dissipation
, e.g. by using suitable mounting
plates, which in turn are attached to the chassis. Heat-conducting
paste should be applied between HV BM and mounting plate, as well
as between mounting plate and chassis.
"
Always monitor the temperature of the shunt and the internal tem-
perature of the measurement module in order to make sure at any
time that they do not overheat.
