Table 2. Inhibit/Enable Logic Table

Use ITT/Cannon mating connector P/N DE15PK87.

Use 20-24 AWG stranded wire.
Output Connections
Installing ring lugs on output bus bars:

When viewed from the rear, the upper left output lug
is Return and the lower right output lug is Positive.

Place ½” or smaller bolt through output lug and ring
lugs from load cables and install retaining nut.

Tighten the nut to a torque of 10 ft/lbs.
Sense Connections

The Javelin III is equipped with Auto-Sense (load sensed at output lugs if remote sense is not connected).

Connector pin J1-13 is the +Remote Sense and J1-14 is the –Remote Sense.

If Remote Sense is desired, connect pin J1-13 to the positive load connection and pin J1-14 to the negative
load connection at the point where regulation is desired.

Attach sense terminals to load using 20-24 AWG stranded, twisted pair wire.

Verify that sense lines are not cross-connected.
