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 loosening.
When using bare conductors, they must be coated with an appropriate antioxidant

connectors do not have to be prepared in this manner.
Replace the transparent plastic cap on the terminal block.
Turn ON the circuit breaker on each of the DC Power Rail Modules.
