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

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

screw terminals on the breaker. If the Air Circuit Breaker
or Insulated Case Breaker has an EntelliGuard

TU or

MicroVersaTrip

PM Trip Unit then you must also wire

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” two-
screw 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.

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

Step 5.
Spectra

Series Switchboards incorporate the

Distribution Cable Junction Box (Cat. Nos. SDCJBB
and SDCJBBC) in the front vertical support for each
Spectra

RMS Breaker with MicroVersaTrip

PM or

microEntelliGuard

Trip Units. Interconnection of the

breakers (Refer back to Figures 1 and 2 for connections)
is accomplished via the Distribution Cable Harness
(Cat Nos. SDCHA11, SDCHA30, and SDCHA60) linking
the Junction Box to the Voltage Module and additional
Junction Boxes.

THE OVERALL MAXIMUM CABLING

LENGTH OF THE SYSTEM IS 40 FEET. Distance includes
the Voltage Module and

ALL breakers (Spectra

RMS

Molded-Case Circuit Breakers with microEntelliGuard

or MicroVersaTrip

PM/Plus Trip Units, Air Circuit

Breakers and Insulated Case Breakers with
EntelliGuard

TU or MicroVersaTrip

PM/Plus Trip Units).
