Wire/Cable Connections at FMU
Make the following wire/cable connections at the FMU:
Many wire/cable connections are made to Phoenix-style pluggable printed circuit board connectors
with terminals closed by turning a screw. Continuity will not exist if insulation is not stripped from the wires
before insertion into the terminal.
1. A/C Power (see Figures 4-4 and 4-5)
Although the output side of the surge protection is a good source of protected power for many
devices, it is protected by a 4 amp fast-blo fuse. The FMU uses 2.4 amps when both heaters are
powered. If the device receiving the power is drawing more than 1.6 amps, it will blow the fuses.
Bien que la sortie de la protection surtension FMU est une bonne source d'énergie protégé pour de
nombreux appareils, il est protégé par un fusible 4 ampères rapide blo. L'FMU utilise 2,4 ampères
lorsque les deux appareils de chauffage sont alimentés. Si le dispositif de réception est la puissance
en tirant plus de 1,6 ampères, ce sera une charge supérieure peut être pris en charge par le fusible
de 4 ampères.
a. Connect the AC hot (black) and neutral (white) wires from the conduit to the corresponding black
and white wires of the Surge Panel 3-wire harness.
b. Connect the ground (green) wire from the conduit, and the green wire of the Surge Panel 3-wire
harness to the ground lug in the bottom right of the FMU pedestal electrical access.
c. Connect the black and white wires of the Surge Panel 2-wire harness to the corresponding black
and white wires from the FMU power switch.
2. Telephone/Two-Way Ringdown Device (see Figures 4-4 and 4-5; not applicable to Satellite FMUs)
a. Connect the two incoming leads of the phone/communications cable to the red and black wires
of the 4-wire harness for the Surge Protection panel.
b. Connect the orange and blue wires of the 4-wire harness for the Surge Protection panel to pins 4
and 5 of the 5-pin plug in location J3 EXTERNAL of the Pedestal I/O Board.
3. Network Cable (see Figure 4-6). Either Cat 5e/6 or fiber optic cable may be run to the FMU, but only
Cat 5e/6 may be terminated in the FMU Network Interface Card (NIC). When fiber optic cable is used
to carry network signals to the FMU, a fiber optic converter will be required to step fiber optic down to
cable. Product Bulletin 178 describes the installation of one common fiber optic converter. Unlike
other wires and cables that connect to the Pedestal I/O Board, the Cat 5e/6 cable must be routed to
the NIC plugged into the mainboard with an RJ45 connector.
4. Quick Stop Button as FMU Stop Switch. The Quick Stop Button has two terminals to receive wire
connections. It removes power by depressing the red mushroom-shaped button. Power is restored
by turning the button clockwise a partial turn until it pops back out to the reset position.
a. Connect the black wire from the FMU power switch to one contact of the Quick Stop Button.
b. Connect the black wire of the Surge Panel 2-wire harness to the other contact of the Quick Stop
Button. It may be necessary to splice some additional 12 AWG THHN stranded wire to this wire
to make it reach the Quick Stop Button.
