5.3 Assembly of the switchgear panels
(Figures 3/5 to 3/6, 3/9,5/4 to 5/17)
Use DIN screws of tensile class 8.8. The tightening
torques for the busbar screw connections with
dished washers are as follows:
The individual installation stages are as follows:
• Transport the switchgear panels to the
prepared installation point in the sequence
shown on the switchgear plan
• Dismantle lifting lugs 1.5
• Remove withdrawable parts 50 from the
switchgear panels and store them with suitable
protection
• Release and remove floor cover 17
• Remove cover 43.1 from the vertical control
wiring ducts at the front right and left of
the panel
• Align the switchgear panels on the foundation
one after another for correct position and
vertical alignment (deviations of the panel
edges from the vertical must not exceed 2
mm, particularly at the front) and bolt the
panels together. It is advisable to start from
the centre when assembling switchgears
with more than ten panels
• Install and screw bushing plates 28 externally
to the right or left hand panel wall
• When the switchgear has been properly
assembled, fasten the panels to the foundation
frame by welding or by using adequate bolts

1) The rated tightening torques for fasteners without lubrication are
based on a coefficient of friction for the thread of 0.14 (the actual
values are subject to an unavoidable, partly not inconsiderable,
spread).
2) Rated tightening torques for fasteners with lubrication in
accordance with DIN 43 673.
3) Thread and head contact surface lubricated.
Consult the detailed technical documentation
for any tightening torques which deviate from
the general table (e.g. for contact systems or
switch terminals).
