Electrical Interconnections
The MegaDySC cabinet and the Automatic Bypass (ABP) Switchboard are 
shipped separately. The customer is responsible for system mounting. All 
interconnecting power cables are provided (shipped inside the ABP switchboard) 
and will be connected by a factory-trained technician during commissioning. At 
installation the loose ends of the main cables will be routed through the bushings 
in the side of the ABP switchboard and connected inside the MegaDySC cabinet 
to the appropriately labeled terminals. A control wiring harness is also provided 
in the ABP and must be connected to the MegaDySC cabinet. This cable harness 
is routed through two large holes, one in the ABP cabinet and one in the 
MegaDySC cabinet, located at the bottom front of the cabinets. The harness is 
plugged into the associated terminal block located in the lower, left corner of the 
MegaDySC cabinet. Finally, the incoming electrical service and outgoing load 
cables are brought in through the top (or bottom) of the ABP switchboard and 
connected to the appropriate bus locations, as shown in 
. AC input is
connected to the bus bar terminals labeled L1, L2, L3 and the protected load is 
connected to the bus bar terminals labeled X1, X2, X3.
WARNING: Equipment must be earth-grounded according to local and 
national electrical codes. Failure to supply proper equipment grounding may 
result in electrical shock or death. All interconnection wiring will be 
installed by a factory-trained technician during system 
commissioning.
