Commissioning
6. Commissioning
6.1. Inspection activities and safety instructions
To commission the circuit-breaker panel, its correct function
is to be ensured by inspecting the following points:
Please compare the data on the rating plate and the data
on the delivery paperwork with the order documentation.
Check the secondary equipment in accordance with the
information in the circuit documentation for the related
switchgear configuration.
Check all screwed connections (cable connections,
operational earthing, panel screw connections) for correct
seating (torque) and proper fastening.
Check the gas filling pressure (see chapter 4.4 and
chapter 4.5).
Check and document the functionality of the protection
systems before commissioning.
When installing a circuit-breaker panel as an end panel,
make sure that the sealing ends are correctly fitted
to the lateral bushings and that the bottom screw
connection point is closed off with the screw plug.
When doing so, observe the assembly instructions
“Panel screw connection for extensible
gae
.630
panels”, document Nr.
MO-153
.
In case of an installed under- voltage release, auxiliary
voltage is required for test operations.
After complete assembly of the switchgear, perform
a power frequency voltage withstand test according
to IEC 62271-200 / DIN EN 62271-200 (VDE 0671-200)
section 7.105.
Equipment damage due to electrical overload!
When performing power frequency voltage withstand
tests, the rated values of the primary components (e. g.
voltage transformers) have to be observed!
6.2. Switching the circuit-breaker panel (manually)
The following operating sequences are to be followed.
The switch panel is delivered with the front panels
earthed (see Chapter 5.3).
SWITCHING ON
• Switch the earthing switch OFF
• Switch the disconnector ON
• Throw the locking lever
• Tension the circuit-breaker’s drive using the hand crank.
• Switch the circuit-breaker ON.
SWITCHING OFF
Check that the switch panel is electrically isolated using
capacitive voltage detecting system (see Chapter 6.5).
• Switching the circuit-breaker OFF
• Throw the locking lever
• Switch the disconnector OFF
• Switch on earthing switch
