WARNING
The following operations require access to
the cable compartment. Before entering,
make sure the switch and disconnector (if any) are in
open position. Check that the cables are de-energized
and that the grounding disconnector is closed.
Prevent any feeding from the cables.
For operations requiring low voltage compartment
maintenance, make sure the cell is de-energized
before entering.
NOTE
• Please refer to the operation and maintenance
manual 1VFM200005 for information on
tightening torques.
• For maintenance activities, use the tools given in
par 4.1 of operation and maintenance manual
1VFM200005
• For electrical applications, refer to the wiring
diagram included with the switchboard
• For electrical applications, check after
installation that electrical wires are not in
contact with moving parts
• Le seguenti operazioni possono essere svolte solo
dopo aver eseguito un training di livello L2 per
manutentori di equipaggiamento in sito. Contattare
ABB per ulteriori informazioni.
