3.6.4 GTN Fan Installation
CAUTION
To avoid damage to the GTN, take precautions to prevent Electro-Static Discharge
(ESD) when handling the GTN, connectors, fan, and associated wiring. ESD damage can
be prevented by touching an object that is of the same electrical potential as the GTN
before handling the GTN itself.
Table 3-13 lists part numbers for the Fan Kit which is used with P1001 only.

The GTN backplate assembly has a cooling fan mounted to it. The cooling fan is mounted to the
backplate assembly at the factory. The fan is necessary for proper cooling and air circulation within the
unit. The fan is powered from the GTN and must be wired to the GTN connector, P1001.
1. Crimp socket contacts onto each wire of the three-conductor wire harness. Strip 0.17” of
insulation from each wire prior to crimping. Insert newly crimped socket contacts and wires into
the appropriate connector housing location as shown in Figure 3-8 and the interconnect drawings
in Appendix E.
2. Plug the three-conductor wire harness connector into the connector on the fan.
