Power Supply Connections
Use wire nuts to connect the primary side of the
transformer (black and white wires) to the
unswitched 120 V, 60 Hz or (yellow and white
wires) to unswitched 240 V, 50 Hz circuit. Connect
the earth ground to the threaded ground stud on
the left side of the enclosure.
Place a wire nut over the unused black or
yellow wire.

Option Bus Wiring Requirements
Use 18 AWG (1.2 mm) or larger wire to connect
option bus devices to the FACP. The total length of
wire connected to the option bus terminals must
not exceed 4,000 ft (1,219 m), regardless of the
wire gauge wire used.
Shared cable is not recommended for
option bus, addressable points bus,
telephone, or NAC wiring.
To comply with UL, do not share
supplementary devices with primary
device on the option bus.
Avoid shielded or twisted pair-wire except for
special applications where a reduced length of
wiring (approximately 50%) is acceptable for
tolerating a harsh electrical environment.
The length of wire allowed between the control
panel and the last device on a wiring run depends
on the existing drawn on that wiring run. Reducing
the number of devices on a wiring run allows the
individual runs to be longer. Use the guidelines in
Table 10
on page 20 where devices are all of the
same type on a given wire run.
