NOTE!
i
HV DTemp-P central units comply with the safety standard EN 61010-1:2010.
All input channels are insulted against each other as well as against
supply voltage and CAN signals. This reinforced isolation is designed for
a maximum of 1000 V RMS. Power supply is galvanically insulated against
CAN. This functional insulation is designed for 60 V DC.
Before connecting any cable, make sure that the applied signals (power
supply and themperature sensors) are within the allowed voltage ranges.

.
NOTE!
i
The isolation barrier can be damaged due to aging, overvoltage, bipolar
voltage, high temperature and mechanical wear! In order to ensure the
proper functioning and the electrical safety of the module, periodical tests
of the reinforced insulation every 12 months are required! 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 61010-1:2010 is carried out at least every 12 months.
If there is reason to assume that the isolation barrier is defective, a
HV isolation test needs to be carried out immediately.
NOTE!
i
Differences in potential between the module (= shield of the interface cable)
and the mounting location can falsify measurement results or destroy the
device.
Make sure that no differences in potential occur when mounting the
device.
Isolate the module from the mounting location, if required.
NOTE!
i
Trouble-free operation and electrical safety can only be ensured if the
module is correctly installed.
Make sure that the measurement module is correctly installed.
Operate the module only within the specified operation environment.
