care is necessary at all times when working with or adjacent to this equipment.
The AC supply must be removed from the drive using an approved isolation device or
parameters specified in the manual. The drive contains capacitors which remain charged to a
potentially lethal voltage after the supply has been removed. Allow at least 2 minutes after
removing the supply before carrying out any work which may involve contact with electrical

the drive - e.g., a latching contactor.
The drive must be grounded by a conductor sufficient to carry the prospective fault current in
the event of a fault. The ground connections shown in he manual must be followed.

A special hazard may exist where the drive is incorporated into a product which is connected
to the AC supply by a plug and socket. When I, the pins of the plug may be
