CAUTION
DO NOT PLACE THE CONCAVE SIDE OF THE STRAIN RELIEF CLAMP (9) ACROSS THE CABLE BUNDLE.
THE CABLE BUNDLE CAN BE DAMAGED.
NOTE
The configuration module and GAE use the same connector pin locations and cannot be used at the
same time.
NOTE
Each tapped hole on the backshell (1) will only take two ring terminals (15). It is recommended to
terminate a maximum of two wires (13) per ring terminal. This necessitates the use of a ring terminal,
#8, insulated, 14-16 AWG (MS25036-153). If only a single wire is left or if only a single wire is necessary
for this connector, a ring terminal, #8, insulated, 18-22 AWG (MS25036-149) can be used. If more wires
exist for the connector than two per ring terminal, it is permitted to terminate three wires per ring
terminal.
For this procedure refer to figure 4-2 and figure 4-3.
