Earthing the feeder
Hazardous voltage
Can cause death or serious injury.
In panels with circuit-breaker, the earthing process is not completed as long as the circuit-
breaker remains open.
➭ Switch the three-position disconnector to READY-TO-EARTH position.
➭ Close the circuit-breaker.
Internal arcing and explosion hazard
Operating the three-position disconnector under load can cause injury or property
damage.
A mechanical interlock prevents, as standard, the three-position disconnector from being
operated under load. The switchgear can optionally be equipped in accordance with a
customer-specific interlocking and control scheme.
➭ If the customer-specific interlocking and control scheme requires that the panel be
provided without electromechanical or mechanical interlocks, the three-position
disconnector can be operated under load.
➭ Do NOT operate the three-position disconnector under load.
