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
screw terminals on the breaker. If the Air Circuit Breaker
or Insulated Case Breaker has an EntelliGuard
TM 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 TM 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 TM
or MicroVersaTrip ® PM/Plus Trip Units, Air Circuit
Breakers and Insulated Case Breakers with
EntelliGuard
TM TU or MicroVersaTrip ® PM/Plus Trip Units).
