CONTROLLER INSTALLATION AND GROUNDING
Locate the FTS 371 FTC controller in an area that will allow proper access to the enclosure. Ensure the mounting
location does not interfere with the quick-release latch that secures the enclosure’s door. Release the latch to
open the door for internal access.
Use the following guidelines for mounting the controller:
Ensure that adequate space exists around the equipment for access during installation, maintenance and
servicing.
Allow space for airflow around the controller. Recommended 3-4” of space allowed on each side of the
controller. Flash Technology does not furnish mounting hardware unless it is ordered as part of an
installation kit.
Flash Technology recommends using flexible conduit for all cable runs with the exception of the beacon
cable and jacketed ground wires.
Ground the controller using a 10 AWG insulated ground conductor crimped into the supplied Yellow ring
terminal. Install the ring terminal at the lower left PCB mounting screw in the controller. Route all ground
conductors down and away from the energized equipment and ensure there are no bends less than 8
inches radius. If installed outdoors the system controller should be bonded to the site grounding grid (via
exothermic welding). If installed inside a shelter or building route the 10 AWG insulated ground wire to
the nearest down-link and attach using a compression fitting (c-tap).
Use the following guidelines for installing the photodiode:
Locate the photodiode where it has an unobstructed view of the polar sky (north).
It must not view direct or reflected artificial light.
Support the photodiode vertically at the top end of a vertical length of rigid conduit to prevent moisture
intrusion.
If possible, mount the photodiode in a location that will allow easy access for future testing.
