Electrical Interconnections
The 800A MegaDySC Module is shipped separately from the Automatic Bypass
Switchboard and the ER Module. The customer is responsible for system
mounting and electrical supply and load connections. All interconnecting bus
bars and power cables are provided and will be connected by a factory-trained
technician during commissioning. At commissioning the bus links will be
connected between the Automatic Bypass Switchboard and the 800A
MegaDySC Module. A control wiring cable is also provided in the Automatic
Bypass Switchboard and must be connected to the 800A MegaDySC Module.
This control cable is routed through two large holes, one in the Automatic Bypass
Switchboard and one in the 800A MegaDySC Module, located at the bottom
front of the enclosures. The cable is plugged into the associated terminal block
located in the lower, left corner of the 800A MegaDySC Module. In ER systems,
two other cable harnesses are routed between the 800A MegaDySC Module and
the ER Module.
Electrical Supply and Load
Connections Electrical termination hardware is supplied with each system. One box contains
all needed hardware for one system installation. The box is labeled:
The incoming 3-phase electrical service and outgoing load cables enter through
the top of the switchboard enclosure and connect to the appropriate bus
locations. To access the main electrical terminals:
1. Remove the CABLE ENTRY PLATE on the top of the switchboard
(Refer to
Figure 1 , Figure 2 , or Figure 3 )
2. Open the two right side doors of the switchboard
3. Remove the dead front panel covering the circuit breakers (4 screws)
(Refer to
Figure 11 ). Remove the transparent shield
The cable entry plate may be fitted for conduit or cable ladder as needed. The
other top panels may also be removed if needed. All panels must be replaced after
installation. Locations of the main electrical terminals are shown in
Figure 12 and
Figure 13 .
WARNING: Equipment must be earth-grounded according to local and
national electric codes. Failure to supply proper equipment grounding may
result in electrical shock or death.
