Chapter 1- Hardware Description

5Connect the green or green-yellow wire to the system single-point M6x15 “Ground” bolt.

The rating of the protective earthing conductor should be a minimum of 10AWG.

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 compound before crimp connections are made. Tinned, solder-plated or silver plated connectors do not have to be prepared in this manner.

6Replace the transparent plastic cap on the terminal block.

7Turn ON the circuit breaker on each of the DC Power Rail Modules.
