Syn-Tech Systems FuelMaster FMU-2500 Classic Installation Manual page 72

3. Drill screw anchor holes for all four corners of the pedestal, then seat the screw anchors.
Screw anchor nuts may be left loose in step 4 to assist with the installation of conduit or liquid-tight
flex up to the FMU pedestal electrical access panel. If additional conduit or liquid-tight flex are not
being installed, the screw anchor nuts should be tightened when initially installed.
4. Mount the pedestal on the screw anchors, and install the screw anchor nuts and washers. If
additional conduit or liquid-tight flex are to be installed, loosely attach the four screw anchor nuts and
washers. Use additional washers for leveling, as required.
Finishing Conduit Connections to FMU Pedestal
If the conduit entering the FMU are installed in accordance with the NEC, there is no code requirement to
enclose the exposed wires. There is, however, a DoD requirement to install liquid-tight non-metallic flex
conduit over all exposed wires between the rigid metal conduit and FMU pedestal electrical enclosure. If
the installation is performed at a DoD site, liquid-tight must be installed to cover/protect all exposed wires
exiting the rigid conduit. Syn-Tech installers install liquid-tight over exposed wires at all installations
regardless if DoD or civilian.
1. Unlock and open the FMU pedestal door.
2. Remove both electrical access cover panels from the pedestal.
3. As required, install any surface mount conduit that may be needed. If holes are cut or punched in the
pedestal to introduce conduit, ensure the entry point is sealed watertight.
4. Pop out the plastic conduit plugs, as required, in the bottom of the pedestal electrical access to
permit entry of the needed conduit.
5. As required/desired, use any approved method (rigid conduit, liquid-tight flex, etc.) to route all
conduit in the pedestal to the conduit openings in the bottom of the electrical access, and secure
with locknuts or liquid-tight couplings.
6. If not previously accomplished, tighten the screw anchor nuts.
Wire/Cable Connections at the Dispensers
The use of explosion-proof conduit and fittings may not be necessary if not working with flammable
fuels dispensers, or outside a hazardous location.
All wire/cable connections terminating at the dispenser must be enclosed in explosion-proof junction
boxes. Wires/cables routed to the FMU from the dispenser must be routed through explosion-proof and
sealed conduit and terminate in the FMU pedestal electrical access enclosure. If the necessary conduit,
seals, and junction boxes are not in place to accommodate the wires/cables and their connections, they
must be added during the installation.
Add fittings, as necessary, to enclose the wires/cables and their connections in explosion-proof
components, and to seal the ends of conduit that surface at the dispenser. Do not seal conduit seal-offs
until all wires/cables have been pulled, and all wire connections are complete.
Pulling Wires/Cables
Section 3 defines wire/cable requirements. Use the following wire/cable recommendations and pull all
necessary wire/cables. Do not make any connections at this time. All wires/cables except network cable
and fiber optic are terminated on the Surge Protection Panel, the Pedestal I/O Board, or the I/O Silver
Board in the FMU pedestal. Network cable and fiber optic are terminated at the network card in the FMU
upper cabinet. Allow for sufficient length to make these connections when pulling wires/cables.
