MOUNTING
The location of the Turbo PMAC Clipper is important. Installation should be in an area that is protected
from direct sunlight, corrosives, harmful gases or liquids, dust, metallic particles, and other contaminants.
Exposure to these can reduce the operating life and degrade performance of the board.
Several other factors should be carefully evaluated when selecting a location for installation:

For effective cooling and maintenance, the Turbo PMAC Clipper should be mounted on a smooth,
non- flammable vertical or horizontal surface.

At least 100 mm (0.4 inches) top and bottom clearance must be provided for air flow.

Temperature, humidity and Vibration specifications should also be taken in account.
Caution
Unit must be installed in an enclosure that meets the environmental
IP rating of the end product (ventilation or cooling may be necessary
to prevent enclosure ambient from exceeding 45° C [113° F]).
The Turbo PMAC Clipper can be mounted as a stand-alone controller using standoffs. At each of the
four corners of the board and at the center edges, there are mounting holes that can be used for this.
The order of the Acc-1P or other stacked accessories with respect to the Clipper Board does not matter.
If the Turbo PMAC Clipper is mounted to a back panel, the back panel should be unpainted and
electrically conductive to allow for reduced electrical noise interference. The back panel should be
machined to accept the standoffs pattern of the board.
The board can be mounted to the back panel using four standoffs and internal-tooth lock washers. It is
important that the teeth break through any anodization on the board’s mounting gears to provide a good
electrically conductive path in as many places as possible. Mount the board on the back panel so there is
airflow at both the top and bottom areas of the board (at least 0.4 inches).
