GEO Direct PWM Amplifiers – Preliminary Documentation
14 Mounting
The drive 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 is machined to accept the mounting bolt
pattern of the drive, make sure that all metal chips are cleaned up before the drive is mounted so there is
no risk of getting metal chips inside the drive.
The drive is mounted to the back panel with four M4 screws and internal-tooth lock washers. It is
important that the teeth break through any anodization on the drive's mounting gears to provide a good
electrically conductive path in as many places as possible. Mount the drive on the back panel so there is
air flow at both the top and bottom areas of the drive (at least 3 inches). If multiple GEO drives are used,
they can be mounted side-by-side, leaving at least one-tenth of an inch clearance between drives. It is
extremely important that the air flow is not obstructed by the placement of conduit tracks or other devices
in the enclosure.
