Attention!
The HV module of the test and diagnosis system contains electrical
energy storage devices also. These devices are discharged in the same
way like the test object by the internal discharging unit of the test device.
To avoid the re-charging by space charges the HV module has to be
immediately equipped by means of the provided shorting device (Fig. 7)
after disconnection of the both components HV module and Operating
module. The shorting device has to be remained at the HV module even in
the case of transportation and storage and may not be removed until the
Operating module had been put on.
Attention! Before each use it has to be checked whether the following components of
the system are intact, dry and clean:
* HV-connector (device side) and end termination (test object side) of
the movable high-voltage connecting
* HV- output socket of the HV module
* HV connector between HV module and operating module
3.2 Electrical Connection for Stand-alone Test Operation
3.2.1 General Rules for Making Connections
Always keep in mind that you are required to comply with all relevant safety precautions
for high voltage and power systems when you bring the system into service!
In particular, make sure that the test object is connected to earth and shorted and the
cable testing apparatus is switched off when it is connected to the test object or
disconnected from it.
It is only for the duration of intrinsic testing that this short-circuit and earth connection
may be removed.
Please regard the discharge switch contained in the device only as a facility for
discharging the capacitors without risk. Do not use it for earthing and shorting according
to VDE 0104!
