Replace the text of this subclause by the following new text:
The direction of operation for actuators of devices shall normally conform to IEC 60447. Where
devices cannot conform to these requirements, e.g. due to special applications or alternative
mounting positions, they shall be clearly marked such that there is no doubt as to the "I" and
"O" positions and the direction of operation".

Add, after 7.1.6.1, the following new subclauses:
7.1.6.2 Supplementary requirements for equipment with provision for
electrical interlocking with contactors or circuit-breakers
If equipment suitable for isolation is provided with an auxiliary switch for the purpose of
electrical interlocking with contactor(s) or circuit-breaker(s) and intended to be used in motor
circuits, the following requirements shall apply unless the equipment is rated for AC-23
utilization category.
An auxiliary switch shall be rated according to IEC 60947-5-1 as stated by the manufacturer.
The time interval between the opening of the contacts of the auxiliary switch and the contacts
of the main poles shall be sufficient to ensure that the associated contactor or circuit-breaker
interrupts the current before the main poles of the equipment open.
Unless otherwise stated in the manufacturer's technical literature, the time interval shall be not
less than 20 ms when the equipment is operated according to the manufacturer's instructions.
Compliance shall be verified by measuring the time interval between
