Uni Instructions
The controller must be mounted suitable housed to
protect it from the weather and from inadvertent
contact with foreign bodies, so the use of the correct
cover is advocated.
The controller mounts via the heatsink as shown in
the diagram, right. Mounting will normally be onto a
metal plate which will act as heatsinking.
Steel is not a good heat conductor -you should use
aluminium or even copper.
Make sure the controller cannot get wet: normally
when mounted as shown and correctly covered water
cannot get onto the circuit board, and water on the
base will do no harm. Make sure water cannot run
down the wires into the controller.
Heatsink mounting holes are tapped M3 and spaced
at 25.4mm (1”).
The integral heatsink is isolated.
