Mechanical and electrical function test

DANGER!
Putting defective switchgear into operation can endanger the life of people and damage
the switchgear.
Never put switchgear into operation if you notice during test operation that a part of
it does not work as described in here.
Perform test operations with auxiliary voltage only!
The mechanical function is tested without high-voltage.
Switch the operating mechanism several times by hand. Check position indicators
and interlocks, and verify smooth operation of covers.
Test fuse tripping with test fuse.
Install and check HV HRC fuse-links.
Check the ready-for-service indicator. Then, the pointer must be in the green area.
Test operation helps you to verify the perfect operation of the switchgear without high
voltage before commissioning.
Switch the three-position switch-disconnector with motor operation several times to
CLOSED and OPEN position.
Make sure that the three-position switch is switched to OPEN position after
completion of test operation.
Switch on all auxiliary and control voltages and verify correct polarity.
Check whether the mechanical and/or electrical interlocking conditions are fulfilled
without using excessive force.
Check whether the switch positions of the three-position switches are displayed
correctly.
If there are any faults that cannot be cleared at site:
Do not put the switchgear into operation.
Inform the competent Siemens representative.
