RF earth (ground) stud (6) If required, use this to make additional RF earth
(ground) connections: refer to Section 3.16.4.
Refer to Figure 1-6, detail A or B. The bottom panel of the Electrics Box has the following
cables and connectors:
Electrics and Control Loom (17) This is used to provide power, measurement signals and
control signals to the Electronics Module.
HCDP electrical supply
cable (18)
This is used to connect the electrical supply from the
Electrics Box to the HCDP pump.
HCDP thermistor cable (19) This is used to connect the output of the thermistor in the
HCDP pump to the Electrics Box.
