Version: B.1
8.1.3 Plug-In Circuit Modules
Each GCP5000 (GCE) plug-in circuit module is equipped with:
•
A dual 43-pin connector on one edge that plugs into a corresponding edge connector
on the motherboard.
•
Locking ejector levers at the top and bottom of each module to facilitate removal
from the case.
•
SSCC IIIi and CPU III Modules include a screw locking mechanism for securing
modules.
WARNING
SSCC IIII MODULES MUST BE SECURED IN PLACE BY A SCREW
LOCKING MECHANISM. ACCIDENTAL REMOVAL OF THE SSCC IIII
MODULE WILL CAUSE THE GATES TO DROP WITHOUT GATE
DELAY AND FLASHING LIGHTS WILL NOT ACTIVATE.
8.1.4 External Wiring Connectors & Wire Size
All external wiring to a GCP5000 (GCE) is by means of plug-in connectors. The orange cage-
clamp connectors for the signal circuits should use 16 to 12 AWG wire. The orange cage-clamp
connector for the Echelon Lon Talk should use communication-grade twisted wires of at least 20
AWG. The green Screw-Lock connectors for the CPU and the SSCC should use 10 AWG wire.
NOTE
Generic spare connectors that are not keyed for specific modules may be
ordered. Refer to the catalog for ordering information.
8.1.5 Wire Preparation
Strip insulation from the end of the wire as follows:
Table 8-1 Wire Preparation Standards
