The following list of checks is provided for reference only. Interconnections must
be completed by factory-trained and authorized installation personnel.
•
Connect each MegaDySC Unit's ground cable to the ground bus in ABP
Switchboard.
•
Connect line side cables from each MegaDySC Unit to the respective line
input bus in the ABP Switchboard labeled L1, L2 and L3 respectively.
•
Connect load side cables from each MegaDySC Unit to the respective load
output bus in the ABP Switchboard labeled X1, X2 and X3 respectively.
Note: It is critical to match the phases on each MegaDySC section.
•
Plug the 4 duplex fiber optic cables into the appropriate transceiver found
on the control PC boards of each MegaDySC Unit's phase inverter
module.
•
Plug in the control wire harnesses that interconnect the enclosures at the
bottom of each unit.
