2. Method:
• Power cable is to be inserted, cut to length
and stripped.
• Reducer rings 17.2 are to be adapted to the
cable diameter and fitted.
• Cable sealing ends 16 are to be prepared and
secured according to the manufacturer's
instructions.
• Cable cores are to be connected to the
prepared connection points 23 with strain
relief.
Cable core crossings are to be avoided.
Other agreed equipment is prepared at the factory,
e.g. for the connection of insulated busbar
capacitance grading devices. Should any particular
work in the panels be necessary during erection at
site, construction drawings and parts lists
according to which this work can be performed are
supplied with the delivery.
5.7.2 Control cables
(Figures 3/7, 3/12, 3/15 and 5/6)
• Control cables are to be inserted into the left-
hand side ducts 1.2.
For the purposes of inserting the control cables,
the floor of the panel on the left-hand side has
been omitted. The wiring is protected by a
sheet-metal duct which extends into the control
cabinet. The duct is covered laterally by 43.1
and 43.2 and is therefore closed off. In the
control cabinet floor, 6 drill holes for reducer
rings are intended.
• The control cable is to be stripped and secured
at the top end of the duct and the cores inserted
into control cabinet D after swinging the terminal-
strip frame upwards.
• The control cable is to be connected to the
terminal strip as shown in the wiring diagram.
• The control wiring connections are to be made
to the adjacent panel using bushing 24.
5.8 Earthing of the switchgear
(Figure 3/12)
• Connect main earthing bar 19 with links 19.1
supplied in every panel.
• Protection wiring connection of the foundation
frame or the erected raised false floor
respectively, should be made.
• Connect the earthing conductor coming from
the earth electrode, preferably via a removable
bolted link for testing purposes, to the main
earthing bar 19 of the switchgear.

5.9 Laying the ring circuits
The ring circuits are supplied rolled up as a bundle
in the control cabinet. They are marked and fitted
with ferrules at both ends. Openings are provided
in the side walls of the control cabinet for these
lines to be looped through from panel to panel.
5.10 Final erection work
• Check painted areas of the switchgear for
possible damage, touching up where required
(see also section 7.4.1).
• Check bolt connections and tighten where
required, in particular all those carried out in on-
site erection of the busbars and earthing system.
• The auxiliary switch for the I
(according to the relevant order) must if
necessary, be effected via the pressure relief
flaps after removing the lifting lug:
– Auxiliary switch push-rod is to be inserted into
the drill hole in the pressure relief flap.
– Auxiliary switch holder is to be adjusted into
the horizontal position (Figure 5/22).
• Clean the switchgear thoroughly.
• Remove all foreign bodies from the panels.
• Replace properly all coverings, etc., removed
during erection and connection.
• In the enclosure, the openings which may
remain are to be closed if they are no longer
needed.
• Check the isolating contacts and interlock
mechanisms for smooth motion, and regrease
with Isoflex Topas NB 52 where required (see
section 7.4.1).
• Withdrawable circuit-breaker parts are to be
inserted and the control wirings connected.
• Panels doors are to be properly closed.
