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

™

EntelliGuard

TU Trip Units in Air Circuit Breakers

PM or

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.

Installation and Connections

Prior to installing the Voltage Module confirm that the
module matches the voltage and system requirements
(refer back to Table 1). Also turn OFF power ahead of the
switchboard before proceeding with these instructions.

Step 1.

®

To install the Voltage Module into a Spectra

Series
Switchboard, first loosen the rail latch screws (A) and
retract latches (B) on both ends of the module as shown
in Figure 7.

Step 3. Finally push inward until the Voltage Module
pressure connectors are fully engaged (plugged) into
the interior bus bars. Release the latches. The latches
will automatically lock into the interior rail when the
module is fully engaged and installed. Tighten the
rail latch screw to bolt and lock the Voltage Module
in Module pressure connectors are fully engaged
(plugged) into place as shown in Figure 9.

Figure 9. Locking the Voltage Module in place.

Figure 7. Retracting the rail latches of a Voltage Module.

Step 2.

Then line up the guides on both ends of the Voltage

®

Module to notches in the Spectra

Series Switchboard

interior vertical rails (C) as shown in Figure 8.

Figure 8. Aligning the Voltage Module.

Once the Voltage Module is locked into place in the
switchboard, wiring to the Voltage Module interior
points should be made.

The screw terminals on the Voltage Module are labeled
by function for clarity (refer back to Figures 5A and 5B
or 6A and 6B for location information). The terminal
strip pockets on all terminals will accommodate a
spade lug or ring terminal with a tongue width up to

0.320 inches. The terminal screw size is 10-32. To make
the connections, attach an appropriate spade lug or
ring terminal to the wire, then slip the fastener beneath
the terminal screw and tighten.

The Voltage Module also contains two 12-pin plug
connectors. The connectors are keyed so they
cannot be inserted incorrectly into a mating 12-pin
receptacle connector. To connect to the Voltage
Module plugs, align the receptacle interlock connector
of a Distribution Cable Harness with the plug hook
connector of the Voltage Module. Insert the receptacle
until the interlock and hook catch (see Figure 10). To
disconnect from the Voltage Module, press down at the
rear of the receptacle interlock until the interlock clears
the plug hook and withdraw the receptacle interlock
(see Figure 11).

screw terminals on the breaker. If the Air Circuit Breaker

TM

or Insulated Case Breaker has an EntelliGuard

®

MicroVersaTrip

PM Trip Unit then you must also wire

TU or

the “OUTPUT TO ACB/ICCB -VI, V2, V3” three-screw
terminal block to the appropriate voltage sensing screw
terminals on the breaker.

These last connections are necessary only when
the Voltage Module is being connected to a +24Vdc
supplemental power supply and/or a communications
network; For supplemental control power attach the
+24Vdc and 24Vdc common wires from the external
power supply to the “SUPP. INPUT 24Vdc” two­screw terminal block. For communications network
connection, attach the black (-) and clear (+) wires of
the network bus to the “Communications” two-screw
terminal block.

®

Note: MicroVersaTrip

PM and microEntelliGuard™
Trip Units communicate via different communication
networks; microEntelliGuardTM uses Modbus and

®

MicroVersaTrip

PM uses Commnet. NEVER connect a

microEntelliGuard™ Trip Unit to a Commnet bus.

Step 4.

IMPORTANT: The following connections are mandatory
and MUST be made for all installations.

First, wire the 1-terminal “GND” screw on the Power
Supply assembly to the switchboard ground. For
catalog numbers ADSVMA120Y and ADSVMA277Y
connect a wire from the appropriate potential
transformer terminal screw on the Voltage Conditioner
Plate to the switchboard neutral bus AND ground
the secondary neutral on one of the potential
transformers.

These additional connections are required if the

®

Spectra

Series Switchboard has Air Circuit Breakers
or Insulated Case Breakers installed; If the Air Circuit
Breaker or Insulated Case Breaker has an EntelliGuard

TM

TU, MicroVersaTrip® PM, or a MicroVersaTrip® Plus Trip
Unit, then wire the “OUTPUT TO 24Vdc” two-screw
terminal block to the appropriate +24Vdc control power

The Voltage Module is now functionally wired and
ready to receive connections to the Distribution Cable
System.

Step 5.

require one additional step. You MUST install an

TM

auxiliary switch (microEntelliGuard

Trip Units require
an auxiliary switch with gold plated contacts) in the
right accessory pouch of the breaker and route the
red and white wires of the switch to the “AUX SWITCH”
two-screw terminal block of the junction box. The
installation of this auxiliary switch will also require that
an IX filler plate (catalog number APPIW) be installed

®

between every Spectra
Breaker with microEntelliGuard

RMS Molded-Case Circuit

TM

or MicroVersaTrip® PM

Trip Unit.

Another use of the junction box (independent of the
Distribution Cable System) is the connection of the

®

neutral current sensor to any Spectra
Case Circuit Breaker with a microEntelliGuard

®

MicroVersaTrip

PM or a MicroVersaTrip® Plus Trip Unit

,

that has the equipment ground fault option. 3Ø/3W

systems need no connection in order to function
properly. Wire the black and white wires of the neutral

current sensor to the “NEUTRAL CURRENT SENSOR”
two-screw terminal block on the junction box.
