5. SYSTEM COMMISIONING AND
DECOMMISIONING
5.1 Commissioning
5.1.1 Preparation and checking
1. Carry out a visual inspection.
Before commissioning the SVS/12 installation, check
that:

the area in which the installation is set up complies
with the guidelines described in chapter 3.1.

the installation is placed sufficiently firm and level.

the cables are located directly beneath the
connections.

the cable connection and the support are properly
tightened.

the phase sequence of the connected cables is
correct.

the earth busbar is earthed.

the lead sheath or earth screens are earthed.

the cable boxes for PILC cables (if used) are
completely filled.

the hose clips (if used) are tightened.

the rated currents of the high-voltage fuses are
correct.

the high-voltage fuses are fitted correctly with the
striker pin in the handle.

the inside of the installation is free of dust.

the blocking pin is removed from any secondary
voltage coils AFTER the secondary voltage is
applied to the installation. The blocking pin is
situated on the coil in the mechanism compartment
(see 6.1.2) and bears a label.

the short-circuiting link on the terminal strip which
short-circuits any current transformer cores
secondarily, is removed AFTER these are
connected to the equipment concerned.
2. Replace all protective panels after checking is
completed.
L
IFE HAZARD
!
When commissioning a metering panel in the
special version with non-insulated copper
connections, all guards against direct or indirect
contact must be in place. Therefore do not
remove any plates from this panel when the
system is live.
L
IFE HAZARD
!
If an SVS/12 panel is commissioned without a
primary cable connected, the panel in question
must be put in the earthing position to prevent
contact with live connection points, that is to
say, the disconnector must be in the earthing
position and the load-break switch or circuit-
breaker must be closed.
3. Then carry out a function test:

Test the switch-on and switch-off functions.

Test the interlocks
