- 1. Route the INPUT power cables (labeled L1, L2, L3) through the top bushing in the right-side wall of the switchboard, labeled “Input to DySC”
- 2. Route the OUTPUT power cables (X1, X2, X3) and Ground cable through the bottom bushing labeled “Output from DySC”
- 3. Route the control cable harness from the lower front switchboard pan into the MegaDySC section through the matching holes in the lower front side panels. Install the 3.5” snap-in grommet so that it protrudes into the MegaDySC cabinet before rout...
- 4. Lockout circuit breakers CBI and CBO in the Automatic Bypass Switchboard.
- 5. Install utility input and load output conductors.
- 6. Energize the switchboard. The MegaDySC touch screen display will be active only if the control harness has been plugged in on the MegaDySC side. If the screen is active then 120VAC is present at several points within the MegaDySC enclosure.
- 7. Push the green CLOSE CBB button to energize loads. The remaining interconnections and commissioning must be completed by factory-trained technicians.
