The Voltage Module contains eight connection points.
Refer to Figures 5A and 5B or 6A and 6B for connection
details and location information. The following is a
detailed list of the Voltage Module connection points:
• “To Distribution Cable” (2x)
– 12-pin plug connectors that mate with the 12-pin
receptacle of a Distribution Cable Harness (catalog
number SDCHA11, SDCHA30 or SDCHA60). If the
Voltage Module is factory installed in a Spectra
®
Series Switchboard these connections are factory
wired to Distribution Cable Junction Boxes (catalog
number SDCJBB).
• “Input”
– Three-screw terminal block on the Power Supply
assembly. Use the one-terminal “GND” screw for
connection of the ground. If the Voltage Module is
factory installed in a Spectra
® Series Switchboard,
this connection is wired to the switchboard
equipment ground (the other two-terminal screws
are pre-wired to the load side of the Power Supply
Plate fuse block).
• “Communications”
– Two-screw terminal block for Modbus
communications link or for Commnet link to the GE
POWER LEADER™ Network.
• “Supplemental Input 24Vdc”
– Two-screw terminal block for connection to an
external +24Vdc power supply.
• “Output to ACB/ICCB”
– Three-screw terminal block for an additional voltage
sensing signal output to MicroVersaTrip ® PM or
EntelliGuard ™ TU Trip Units in Air Circuit Breakers
and/or Insulated Case Breakers.
• “Output to 24Vdc”
– Two-screw terminal block for an additional control
power output to MicroVersaTrip ® or EntelliGuard ™
TU Trip Units in Air Circuit Breakers and/or Insulated
Case Breakers.
• Three-phase rear pressure connector
– Provides an AC source connection for control power
and voltage sensing signals. If the Voltage Module is
factory installed in a Spectra
® Series Switchboard,
these connections mate with the vertical bus bars in
the switchboard. For catalog number ADSVMA120Y
and ADSVMA277Y, an additional AC neutral
connection must be made at one of the potential
transformers. This connection is factory wired if the
Voltage Module is factory installed in a Spectra
®
Series Switchboard.
Dimensions, Weights and Wiring Diagrams
A Voltage Module dimensioned drawing is provided
in Figure 4 to assist in mounting the accessory. The
maximum unit weight is 38 pounds.
