Reserved (TB2)
Terminals 211 and 212 are reserved for future design efforts. Do not
connect circuits to these terminals.
VT Terminals (TB2)
Pins 213–218 are phase A, B, C, Auxiliary and ground voltage inputs
from the VT (voltage transformer) module. The VT module is used to
measure the line voltage and steps down the voltage to a smaller
potential. It also provides isolation to the FP-5000 and from the
voltage bus.
Figure 6-8
through Figure 6-11
show Delta and Wye
connected feeder protection, respectively.
Note:
Careful attention should be made to the phase wiring to
avoid erroneous power and voltage indications as well as
damage to the FP-5000.
Standard Communication Board TB3
There are three circuits on the “Standard communication” Terminal
Block assembly TB3:
• J1 INCOM PN – is the connection of a PowerNet INCOM twisted
pair communications interface. The connection is part of a daisy
chained multi-point twisted pair interface. J1-1 and J1-2 are for the
twisted pair connections and J1-3 for shield termination. The
removable terminal plug can facilitate debug of the INCOM
hardware interface. Switch selectable termination is located on the
communication board of the inner chassis and can be accessed
through an opening in the metal chassis with the drawout removed.
It is shipped open. Refer to Section 10 for INCOM wiring rules and
details.
• J2 INCOM AB – this is an INCOM type interface reserved for future
design features. The hardware is identical to J1 accept that there is
a non-switch selectable 100 ohm termination resistor
built in.
• J3 Zone Interlock – This is the termination for both the zone
interlock Zone Out (J3-1) and Zone In (J3-4) circuits with duplicate
J3-2 and J3-5 Zone com. connections, for Zone signal returns. The
shield connection J3-3 is grounded to the chassis and is not
needed for noise immunity. Twisted pair control wiring of 14-18
AWG is recommended.
• J4 and J5 are un-populated future design options.
It is recommended that the wires terminated at TB3 be fitted on the
end with ferrules to eliminate fray shorting and the cable stress
released by strapping them to the back of the drawout panel near the
FP-5000.
