WARNING
General safety instructions for set-up and commissioning
• The safety guidelines for the operation of mobile testing systems often
differ from one network operator to another and are frequently subject
to national regulations (such as the German BGI 5191). Before the
measurement session, find out what the applicable guidelines are and
follow the rules set out therein precisely, in respect of the organisation
of work and the commissioning of the mobile test system.
• Select a location that is sufficient for the weight and size of the system
and which ensures that it stands securely.
• When setting up or connecting the device, make sure that it does not
impair the functional capability of any other systems or components. If
other systems and components have to be modified, be sure to
reverse these measures once the work has been completed. 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.
• In the event of large differences in temperature 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 devices caused by voltage flash-overs,
the system must not be operated when in this condition. It should
rather be left in the new environment to acclimatise for approximately
one hour before putting it into operation.
3.1 Electrical Connection
WARNING
Safety instructions for the electrical connection
• The system may only be connected to de-energized equipment. The
general safety instructions and, in particular, the five safety rules (see
page 8) must always be followed prior to connection to the test object.
• Follow the specified connection sequence.
• All the cables at the measuring point that are out of operation and are
not to be tested must be shorted and earthed.
• Because the amount of voltage applied to the test object poses a
danger in the event of contact, the test station itself and the ends of
the cables must be shielded as per VDE 0104 to ensure that such
contact is not possible. When doing so, be sure to take all branches of
the cables into account.
