9GHA l Switchgear extension and replacement of a panel
Extension of an existing double 3
busbar switchgear system
Safety provisions3.1
Warning!
Comply with the safety provisions on page 6.
Warning!
Confusing the busbar system involves a risk of injury. The term
Busbar 1 (BB1) refers to the busbar arranged in the rear area of the
panel, and the term Busbar 2 (BB2) to the busbar arranged in the up-
per part of the panel.
During assembly, busbar 1 and busbar 2 must be identified clearly.
Earthed as well as energized busbars must be identified by the ap-
propriate warning and information signs.
Warning!
Risk of injuries. The mounted black end caps on the busbar ends
and the silicone sleeves of the busbar link are surge-proof and must
not be subjected to any mechanical stress.
Warning!
The initial position as shown, and the workflow described are in-
tended as examples only.
Before assembly is started, a complete description of the entire
workflow of a switchgear extension must be prepared and verified in
accordance with the local circumstances and conditions.
Important information3.2
The surge-proof black end caps and the silicone sleeves of the busbar
links are safe to touch due to an earthed external conductive surface.
Before positioning new panels, insert the busbar clamping contacts into
the busbar tubes of the left-hand panel concerned. Inserting the clamping
contacts after screw-fastening the panels would be very time-consuming.
The silicone link sleeves connecting the existing switchgear panel to the
extension panel may only be mounted on site.
