Pedestal I/O Board. Master FMU/EIU communications cables cannot be “daisy-chained” between
EIUs. Individual communications cables are necessary from the Master FMU to each EIU.
c. Control of Accessory Controller. Pull two 14 AWG THHN wires from the EIU to the accessory
controller. The wiring diagram in Figure 4-27 calls out blue and orange, but any color may be
used which are easily identifiable when making the wire connections. Ensure approximately 3 feet
of excess wire is extending from the conduit to facilitate wire connections after EIU installation.
NOTE
The seal-offs cannot be accessed after the EIU is mounted over the conduit.
2. As required, pour seal-offs on any conduit routed from/to a hazardous location.
Mounting the Pedestal (see Figure 4-26).
A rigid base is necessary for mounting the EIU. Asphalt is not a satisfactory mounting surface. Perform
the following to mount the Pedestal:
1. Position the Pedestal centered over the conduit.
NOTE
The Pedestal is made to accept 3/8 inch screw anchors. Use of stainless steel screw anchors, nuts, and
washers will prevent corrosion and permit the pedestal to be removed and replaced, if necessary, at any time
during the life of the EIU.
2. Mark screw anchor holes for all four corners of the Pedestal.
3. Remove the Pedestal and drill screw anchor holes.
NOTE
There are no side access panels. The wires exiting from the three conduit must be routed up through the
Pedestal and out the cabinet mounting plate hole before the Pedestal is anchored.
4. Attach a pull string to the wires.
5. While repositioning the Pedestal over the conduit, pull the pull string and wires up through the
Pedestal and out the top of the Pedestal.
