6. Assembly of the switchgear at site
6.4 Procedure for setting-up
the doors
Instructions from the standpoint of the safety at
work: The relevant work and adjustments must be
carried out by trained specialists familiar with
the installation, taking into account all relevant
safety regulations according to IEC and other
relevant professional bodies, and other local and
works regulations and instructions.
The switchgear doors are always mounted and
set up at the factory. It is always necessary to
reset these doors on site and to do this before
commissioning the switchgear. During
setting-up, the switching station must be
connected to the control voltage, otherwise it will
not be possible to operate the withdrawable part
with circuit-breaker / contactor and earthing
switch. The working method:
The circuit-breaker compartment door:
• Loosen (but do not dismantle) 2 lock screws
M6 (Figure 80) on the lateral side of the door
- this releases the blocking stop and it is
possible to open the door.
• Withdraw the withdrawable part with circuit-
breaker / contactor from the circuit-breaker
compartment onto the service truck and
move it outside of the switchgear.
• Dismount the left lateral cover of the control
cables (Figure 81).
• Withdraw the left lateral cover of the control
cables from the circuit-breaker compartment
outside of the switchgear (Figure 82).
• Loosen (but do not dismantle) all M8 screws
at all hinges (Figure 83).
• The setting-up of the door position is based
on rotating the door in the opening on an
axis of the middle hinge (the second hinge
from the bottom edge of door in the case of
a door with 4 hinges).
• Set up the door in the position in which its
upper edge is parallel with the gap between
the circuit-breaker compartment and the low
voltage compartment (Figure 84).
• Tighten the upper hinge and check the
correct function of the door including the
insertion of blocking lever in the door slot
with the blocking stop.
• If the door closes correctly, tighten all screws
at all hinges to a torque of 20 Nm.
• Set up the blocking stop so that its lower
edge is in the range of 29.8-30.3 mm above
the level of the lower edge of the slot in the
door draw bar when the door handle is in the
closed position (Figure 85) (Figure 86). The
required position of the stop can be set up by
insertion of the jig OCA0071, drw.No.
1VL7611226P0101.
• Check that the door closes correctly.
• Mount the left lateral cover of the control
cables. The screw tightening torque must not
exceed 2,5 Nm.
• Insert the withdrawable part with circuit-
breaker / contactor in the circuit-breaker
compartment and leave in the test /
disconnected position.
• Close the door and verify the door blocking
function by operation with the withdrawable
part.
The cable compartment door:
• Loosen (but do not dismantle) 2 M6 lock
screws (Figure 80) on the lateral side of the
door - this releases the blocking stop and it is
possible to open the door.
• Withdraw the withdrawable part with
measuring voltage transformers (if the
switchgear is equipped with them) from the
cable compartment outside of the
switchgear.
• Dismount the left lateral cover of the control
cables (Figure 87).
• Withdraw the left lateral cover of the control
cables from the cable compartment outside
of the switchgear (Figure 88).
• Loosen (but do not dismantle) all M8 screws
at all hinges (Figure 83).
• The setting up of the door position is based
on rotating the door in the opening on an
axis of the middle hinge (the second hinge
from the bottom edge of door in the case of
a door with 4 hinges).
• Set up the door in the position in which its
upper edge of door will be parallel with the
upper edge of the separating cover (Figure
89).
• Tighten the upper hinge and check the
correct door function including the insertion
of the blocking lever in the door slot with the
blocking stop.
• If the door closes correctly, tighten all screws
at all hinges to a torque of 20 Nm.
