HV DTemp Measurement System – Safety Instructions
User Guide 8 Version 01.00 // 2021
2 Safety Instructions
This chapter contains important safety information. Please read the following paragraphs
carefully.
2.1 General Safety Instructions
HV DTemp measurement systems are designed and manufactured to comply with the relevant
safety standards. Nevertheless the risk to the life of users and of property damage cannot be
excluded. Especially when work on HV-battery systems is carried out, there is a considerable
potential for danger. This also applies to the assembly and installation of controllers and
sensors of an HV DTemp measurement system in HV batteries.
WARNING!
HV DTemp measurement systems are used in high-voltage applications.
Working under voltage (e.g. when handling HV batteries) carries the risk
of life-threatening electrical shocks.
 Make sure that work is only carried out by qualified and trained
electricians (DIN VDE -).
 Observe safety instructions.
WARNING!
HV DTemp-P central units are applied in high-voltage applications.
Improper use can be life-threatening due to high voltage.
 Make sure that this work is only carried out by qualified and trained
personnel.
 Observe safety instructions.
WARNING!
Connecting CAN bus measurement modules to an existing CAN bus system
may affect the CAN bus behavior.
Improper handling of a CAN bus system may endanger life or cause
damage to property.
 Always connect CAN bus measurement modules to a separate CAN
bus system (measurement bus).
 Make sure that this work is only carried out by qualified and trained
personnel.
CAUTION!
The surface of the module may become very hot when ope-
rated in specific environments (e. g. engine compartment).
Touching the surface can cause serious burns.
 Let the device cool down before handling.
 Wear appropriate safety gloves, if required.

HV DTemp Measurement System – Safety Instructions
User Guide 9 Version 01.00 // 2021
NOTE!
i
HV DTemp-P central units comply with the safety standard EN-:.
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  V RMS. Power supply is galvanically insulated against
CAN. This functional insulation is designed for  V DC.
 Before connecting any cable, make sure that the applied signals (power
supply and themperature sensors) are within the allowed voltage ranges.
→See "HV DTemp" datasheet for further information.
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  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-: 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.
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.
→See "HV DTemp" datasheet for further information.
2.2 Obligations of the operator
f The operator must ensure that only qualified and authorized personnel are entrusted
with handling the product. This applies to assembly, installation and operation.
fIn addition to the technical product documentation, the operator may have to provide
further operating instructions in compliance with the Act on Occupational Safety and
Health.

2.3 Intended use
fHV DTemp measurement systems were developed for temperature measurements in
high-voltage environments.
fThese measurement systems may only be used for the above-mentioned purpose and
under the operating conditions stated in the technical specifications.
→See "HV DTemp" datasheet for further information.
fOperational safety can only be ensured if the module is used in accordance with its
intended use.
fCompliance with the intended use also means that this user guide must be carefully read
and the instructions contained must be observed.
fInspection and repair work must only be carried out by CSM.
fThe operator is solely responsible if the measurement module is used in a way that does
not comply with its intended use.

HV DTemp Measurement System – Product Description
User Guide 11 Version 01.00 // 2021
3 Product Description
The following sections contain general information about the product. Specific technical
information can be found in the datasheet.
→See "HV DTemp" datasheet for further information.
The HV DTemp measurement system from CSM has been developed for the precise, digital
and thus interference-free recording of up to 512 temperature measurement points via a
single cable connection to the HV DTemp-P central unit. A HV DTemp measurement system
consists of a HV DTemp-P central unit, at least one HV DTemp-M controller and the required
sensors (sensor assemblies or single sensors).

HV DTemp Measurement System – Product Description
User Guide 12 Version 01.00 // 2021
3.1 Connections and components
3.1.1 HV DTemp-P central unit
The HV DTemp-P central unit features two galvanically isolated inputs which allow tempera-
tures to be recorded from two different high-voltage areas (HV batteries).
A maximum of eight controllers can be connected to the measurement inputs of an HVDTemp-P
central unit. The controllers can be distributed to both measurement inputs or connected to
only one of them. A controller has 16 digital inputs for a maximum of 64 measuring points. Thus,
up to 512 (8 x 64) measuring points can be connected to one HV DTemp-P central unit.
→ See chapter 3.1.2 "HV DTemp-M controller".
Communication between the HV DTemp-P central unit and the configuration software or
data acquisition system is performed via CAN bus. Each measuring point is assigned its own
CAN ID and this is documented in a DBC description file. The temperature sensors can thus
be uniquely assigned and identified. Data transmission on the CAN bus is potential-free in
"free running" mode.

3.1.2 HV DTemp-M controller
HV DTemp-M controllers handle the addressing and power supply of the sensors. They
record the digital signals of the temperature sensors and transmit the temperature
values to the central unit (Fig. 3-2). One controller provides 16 digital inputs for up to 16
(HVDTemp-M16) or 64 measuring points (HV DTemp-M64). The 4-pin sockets ➁are used to
fconnect the controller to the central unit HV DTemp-P using a high-voltage-safe cable
or
fdaisy-chain the controller to a further controller using a connection cable.
It is possible to connect up to eight2HV DTemp-Mx controllers to one HV DTemp-P central
unit, depending on the license and thus the maximum number of measuring points.

For trouble-free operation and a long product life, certain requirements for mounting and
installation must be taken into account.
4.1 Before mounting
HV DTemp-P central units are equipped with a GORE™ membrane. This membrane is needed
to regulate pressure and humidity. To ensure reliability and performance of the device, it
is absolutely essential that the small ventilation inlet in the rear side of the housing is not
blocked or restricted in any way. If this happens, condensate will accumulate inside the
housing and damage the measurement module.
NOTE!
iThe GORE™ membrane is required to regulate pressure and humidity.
 Do not block the ventilation opening for the GORE™ membrane
during installation or use.
NOTE!
i
Trouble-free operation and electrical safety can only be ensured if the
module is correctly installed.
 Ensure correct installation.
 Operate the module only within the specified operating environment.
→ See "HV DTemp" datasheet for further information.
4.2 Mounting an HV DTemp measurement system
NOTE!
i
Strong magnetic fields, such as those induced by permanent magnets,
may impair the trouble-free operation of the module.
 Never attach the module to a permanent magnet.
NOTE!
i
Making mechanical modifications to the housing, such as by drilling
additional holes, can impair the function of the measurement module
or destroy it. Additionally this would invalidate the warranty.
 Never make any mechanical modifications to the housing.
 Observe mounting instructions.
