16.6 Operating the switchgear for test
SIMOSEC switchgear is operated mechanically and electrically for test at the factory.
Before commissioning, operate the switchgear again mechanically and electrically for
test.
Mechanical operation The panels are delivered from the factory with all switching devices in "GROUNDED"
position, and the closing and opening springs of the stored-energy mechanisms partially
charged.
Ö Operate the different switching options of each panel several times.
Ö Switch the three-position switches several times to each position (CLOSED, OPEN,
and GROUNDED), verifying the correct indication of the associated switch position
indicators at the same time.
Ö Test interlocking conditions of each switching option (without using excessive force).
The switch positions of the SIMOSEC switchgear are described in the operating
instructions
Testing low voltage system
Ö Check the auxiliary circuits according to the circuit diagram and manual.
Ö Switch on control voltage using an external source.
Ö Check the indicators according to the circuit diagram and the mimic diagram of the
switchgear.
Ö Check the control elements according to the circuit diagram and the mimic diagram
of the switchgear.

Electrical operation The switch positions of SIMOSEC switchgear are described in the operating
instructions.
Ö Operate the different switching options of each panel several times.
Ö Verify correspondence between the switch position indication on the control panel
and the actual switch position using the view port.
Ö Test interlocking conditions of each switching option (without using excessive force).
