GEH-6257 Installation Instructions
The Distribution Cable Terminal Block can also be used
to provide a connection into or out of the Distribution
Cable System. The system is used to carry a variety
of electronic signals between Spectra
® RMS Molded
Case Circuit Breakers with microEntelliGuard TM or
MicroVersaTrip ® PM/Plus Trip Units and Distribution
Cable accessories. The electronic signals supported
by the Distribution Cable System vary depending on
the type of molded-case circuit breaker used; a list of
supported signals appears below.
Spectra ® RMS Breaker with microEntelliGuard TM or
MicroVersaTrip ® PM Trip Unit
• Control power (+24vdc)
• Control power (-common)
• System communications (Comm. +)
• System communications (Comm. -)
• Voltage A f (must be from Voltage Module or Voltage
Conditioner Plate or Voltage Conditioner Assembly)
• Voltage B f (must be from Voltage Module or Voltage
Conditioner Plate or Voltage Conditioner Assembly)
• Voltage C f (must be from Voltage Module or Voltage
Conditioner Plate or Voltage Conditioner Assembly)
Spectra ® RMS Breaker with MicroVersaTrip ® Plus or
microEntelliGuard TM (with Basic Metering) Trip Unit
• Control power (+24vdc)
• Control power (-common)
Figure 3 shows the individual breaker input connector
pinout for the Distribution Cable Terminal Block for
each type of trip unit, and Figure 4 shows the system
connector pinout for the Distribution Cable Terminal
Block for each type of trip unit.
To use the Distribution Cable Terminal Block to provide
a connection into or out of the Distribution Cable
System, you must use one of the Distribution Cable
Harnesses (cat. nos. SDCHA11, SDCHA30 or SDCHA60
as a jumper into a Distribution Cable Junction Box (cat.
no. SDCJBA).
A Distribution Cable Terminal Block dimensioned
drawing is provided in Figure 5 to assist in mounting the
accessory.
