Mechanical Installation
Mounting location
Mechanical installation has to take into account points
of entry of electrical cables and the fitting of a choke if
required.
The Drive should be located in a place free from dust,
corrosive vapours, gases and all liquids.
Two alternative arrangements for mounting the Drive
are provided. Depending on the position of mounting
brackets, these are:
Surface mounted on a panel or in an enclosure
Through an aperture in a panel so that the
heatsink of the Drive projects from the rear of the
panel. This arrangement can be used for
mounting the Drive through the rear panel of an
enclosure to allow free circulation of air around
the heatsink and to minimize temperature rise
inside the enclosure. This can be beneficial if the
enclosure is to house a number of Drives.
Each mounting bracket is mounted to the heatsink by
two self-tapping screws.
