5 Erection of the switchgear at site
In the interests of the best possible erection
sequence, and in order to ensurea high quality
standard of the panels, local installation of the
switchgear should only be carried out, or at least
responsibly managed and supervised, by specially
trained skilled personnel.
5.1 General site requirements
At the start of erection, the switchgear room at
site must be complete, fitted with lighting and
power for the erection work, lockable, dry, and
with good ventilation facilities. All necessary
provisions for laying of the power and control
cables such as openings, ducts, etc. must
already be in place.
Compliance with the conditions for indoor
switchgear to VDE 0670 Part 1000 and IEC
62271-1, including those for the " minus 5 indoor "
temperature class, must be ensured.

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). Rated tightening torques for fasteners
with lubrication in accordance with DIN 43673.
2) Thread and head contact surface lubricated.
3) These values apply to welded studbolts only.
Any tightening torques which deviate from those in the general
table (e.g. for contact systems or device terminals) are to be
taken into account as stated in the detailed technical
documentation. It is recommended that the threads and head
contact surfaces of bolts should be lightly oiled or greased, so as
to achieve a precise rated tightening torque.

Remove any dirt from the surfaces in general and
from insulating material surfaces. Observe the
cleaning instructions in Section 7.2

5.2.2 Perform the following work to prepare
silicone insulating parts for assembly
•
Inspect the sillicone insulating parts
•
Clean soiled silicone insulating parts
•
Grease the insulating parts
•
Clean the sockets, the contact tubes and the
outer cone
Inspecting the silicone insulating parts
Only remove the relevant component from
its protective packaging immediately before
assembly.
Check the silicone insulating part for
damage prior to installation.
If you note any damage on the silicone
insulating part, only use the component
after this has been agreed with our service
department.

Cleaning of contaminated silicone insulating

parts
•
Remove surplus or dirty grease from the silicone
part with a soft, clean, non-fraying cloth
•
Clean the silicone insulating part using a soft,
clean, non fraying cloth and cable cleaner MAB
(GCE00910000P0100). Only moisten the cloth
slightly with cable cleaner. Apply only moderate
pressure when cleaning the black areas of the
silicone insulating parts on busbar connections.
Do not wipe from the black areas towards the
light insulating surfaces
•
After cleaning, wipe off surplus cleaner with
a dry cloth. As the cleaner causes the silicone
to swell slightly, it then has to dry for approx.
15 minutes in the air
, avoid any escape of gas into
