Provision for connecting a field installed grounding conductor is
provided on each controller. It is shown in Figure 3.10 and is located

If the protective conductor is not connected to the heatsink, the
plating and/or paint must be cleaned from the four mounting holes or
four star washers (tooth lock washers) must be used.
