Installing the Extended Interface Board
1. Determine the installation location and install using
the six (6) screw locations.
2. Install a ground wire from the EIB panel to the
ground bus bar.
If possible, install the ground lug to the rear of the
EIB panel where the surface is not painted.
Alternately, remove paint from around one hole on
the front of the panel’s mounting flange.

For best performance, equipment ground wires
should be constructed using UL-listed compression-
type connectors and 14-gauge or larger stranded
ground wire. Always use gradual bends in the wire
(no sharp angles).

4.5 CABLE CONNECTIONS
Figure 4-1 represents a 4-channel rackup. Up to four (4) rackups similar to that shown in Figure 4-1 may
be connected for a maximum of 16 RF channels at one site. Backplane connections at each of the four
rackups are similar with only cable additions for interconnecting the multiple rackups.
