in the event of a withdrawable circuit breaker, take action with the circuit breaker withdrawn from the ﬁxed part;

when taking action on circuit breakers with a ﬁxed design, or on the ﬁxed parts of a withdrawable breaker,

disconnect the supply to the power circuit and to the auxiliary circuits, and earth the terminals in a clearly

visible manner, both on the power side and on the load side;

make the equipment safe in accordance with current laws and standards.

These servicing procedures shall be handled only by qualiﬁed personnel with a thorough understanding of the

This procedure does not include instructions on safety or on maintenance and repair operations.

It is important to note that this procedure contains warnings and precautions against maintenance methods that

could cause injury to people, damage to devices or that could make them unsafe. These warnings do not cover all

the ways in which maintenance, even if not recommended by ABB, may be performed, or the possible dangerous

consequences that may arise from such actions.

Anyone who uses procedures and tools for maintenance, whether it is recommended by ABB or not prescribed,

must make sure that his/her own safety and that of the devices is not compromised by the method and by the

service tools used.

Should the need arise to obtain further information or should particular problems arise, and the information in this

procedure is not suﬃciently clear, please contact the ABB Service representative.

When the switchgear is left unattended, even momentarily, the buyer, installer or end user is responsible for

ensuring that the hazard signs are positioned correctly, and that all access and control devices are locked securely.
