3 Setting Up the System
WARNING
Safety instructions for setting up
•
Select a location which is sufficient for the weight and size of the system and ensures
that it stands securely.
• When setting up the testing system, ensure
that it does not impair the function of any
other systems or components. If other systems and components have to be modified
in order to set up and operate the test system, be sure to reverse these actions when
th
e work is finished. Always take the special requirements of these systems and
components into account and only carry out work on them after consulting and
obtaining approval from whoever is in charge of them.
• Install protective equipment (such as railings,
chains or bars) near the test object to
block access to the danger zone and prevent the risk of touching live parts.
• The ventilation slits on the front and back sides of the front panel must not be covered.
• In the event of larger differences in temperatur
e between the storage and installation
locations (cold to warm) condensation may form on components carrying high voltage
(condensation effect). To avoid any risk of damage to people and components caused
by voltage arc-overs, the device needs to be acclimated for about half an hour while
being switched on (fans are running) before high voltage operation can be started.
3.1 Electrical Connection
WARNING
Safety instructions for the electrical connection
• Always follow the safety instructions in chapter 1 - in particular the five safety rules -
before connecting the test object.
• The test system may on
ly be connected to or disconnected from a test object when it
is switched off, and only when the test object is earthed and shorted.
•
Since the voltage applied to the test object can assume values that pose a risk of
incidental contact, the cable ends must
be shielded in accordance with VDE 0104 to
avoid this. When doing so, be sure to take all cable branches into account as well.
•
After granting clearance to the test object, make sure that dangerous voltage cannot
reach unprotected places or technical equipment.
•
The discharge switch installed in the device is merely an apparatus for safely
discharging capacitance, and not an earthing and shorting device as described by
VDE 0104.
• Before operating the system, any existing voltage transformers must be disconnected
from the test object.
•
All cables which are out of operation and not connected to the test system must be
shorted and earthed.
