SG4000 Installation and Operation Manual

You can distinguish the SG4000 1 GHz port entry assemblies by the addition of a terminal

clamp block on the bottom of the port entry board. The terminal clamp secures the AC wiring

that connects each of the port entry assemblies. The 870 MHz port entry assemblies have the

AC wiring soldered directly to the board. The terminal clamp design on the 1 GHz model

enables field personnel to replace the port entry board if necessary.

Figure 2-10 illustrates a bottom view of the port entry board and the AC terminal clamp.
