WARNING! before proceeding with any maintenance operation, it is mandatory to:
• Set the circuit-breaker to the open position and make sure that the springs of the
operating mechanism are discharged.
• In the case of a withdrawable circuit-breaker, extract the circuit-breaker from the fixed
part (see the indication DISCONNECTED)
• If work must be performed on fixed circuit-breakers or on fixed parts, disconnect the
power supply to the power circuit and auxiliary circuits and visibly ground the terminals
on both the supply side and load side.
• Use adequate personal protection equipment, ensure that the apparatus is in a safe
condition and proceed in accordance with the Laws in force.
Skilled personnel
The maintenance operations must be carried out by Skilled Personnel:
