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
Figure 6 . 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.
