HV Breakout Module – Safety Instructions
Installation Manual Version . //
CAUTION!
The measurement module heats up considerably if it is
operated in a corresponding working environment (e.g.
engine compartment). The shunt also heats up consider-
ably during operation under high load. The surface and the
inside of the measurement module can therefore become
extremely hot.
A permanent measurement of high currents should be
avoided in order to prevent the internal temperature of
the module from exceeding the permissible range.
Touching the surface may cause serious burns.
)Let the measurement module cool down before handling,
especially before opening the orange-colored cover.
)Wear appropriate safety gloves, if required.
HNOTE!
i
The isolation barrier can be damaged due to aging, overvoltage, bipolar
voltage, high temperature and mechanical wear! In order to assure the
proper functioning and the electrical safety of the measuring module,
periodical tests of the reinforced insulation every months are requi-
red! If there is reason to assume that the isolation might be defective,
a test should be carried out immediately before putting the device in
operation again.
" Make sure that a high-voltage isolation test according to
EN-: is carried out at least every months.
" If there is reason to assume that the isolation barrier is defective,
a HV isolation test needs to be carried out immediately.
HNOTE!
i
The threaded mounting hole is designed to connect the housing to the
vehicle chassis or to protective ground (PA/PE) in a test bench.
" Do not use the threaded mounting hole for any other purpose,
e.g. for mounting the device.
→ See chapter ... "Ground connection".
NOTE NOTE!
i
Differences in potential between the measurement module ( shield of
the interface cable) and the mounting location can falsify measurement
results or destroy the measurement module.
" Make sure that no differences in potential occur when mounting the
device.
" Isolate the measurement module from the mounting location, if
required.
NOTE NOTE!
i
Trouble-free operation and electrical safety can only be ensured if the
measurement module is correctly installed.
" Make sure that the device is correctly installed.
" Operate the measurement module only within the specified opera-
ting environment.
