DDITIONAL NFORMATION
The rating of the protective earthing conductor should be a minimum of 10 AWG.
If the unit is rack mounted, the single-point ground on the MCU must be
connected to the rack with a single conductor and fixed as to prevent loos-
ening. When using bare conductors, they must be coated with an appropriate
antioxidant compound before crimp connections are made. Tinned,
solder-plated or silver plated connectors do not have to be prepared in this
manner.
7. Replace the transparent plastic cap on the terminal block.
