Curtis PMC 1297 Manual
7
Preliminary on Verso page is set with right edge at 7 and 7/8,
and the top (as on the Recto page) at 1/4.
A 6-pin low power Molex connector (J2) is provided for the tiller multiplexer
controls. The mating connector is a Molex Mini-Fit Jr. p/n 39-01-2065 using
type 5556 terminals. The multiplexer uses four of J2’s six pins: 2, 3, 4, and 6.

threaded to accept M8 bolts, and the
F1
and
F2
bus bars
are threaded to accept M4 bolts. This provides secure
vibration resistant connections on all power terminals.
The tightening torque applied to the bolts should not
exceed the following limits:
M8 bolts:
16.3 N·m (12 ft-lbs)
M4 bolts:
5.4 N·m (4 ft-lbs).
Exceeding these specifications could damage the bus bars’
internal threads, resulting in loose connections.
For applications not using the multiplexer, J2 can be used as an alternative
connector for the display. The display uses only three of J2’s six pins: 1, 2, and 5.
A 4-pin low power connector (J3) is provided for the 13XX programmer. A
complete programmer kit, including the appropriate connecting cable, can be
ordered; see Curtis PMC programmer manual for further information on the
various programmers available for programming Curtis PMC controllers.
J3 can also be used for the display. Although the display is typically wired
directly into Pins 13, 15, and 16 of the 24-pin connector (J1), it can alterna-
tively be plugged into J3 and unplugged when the programmer is used. Only
Pins 2, 3, and 4 of J3 are needed for the display.
High Current Connections
Six tin-plated solid copper bus bars are provided for the high current connec-
tions to the battery
(

, the two motor armatures (
TRACTION
and
PUMP
),
and the traction motor field connections
(
F1
and

)
, located as shown in Figure 2.
The bus bars incorporate threaded mounting studs designed to accept mounting
bolts. This simplifies the assembly and reduces the mounting hardware neces-
sary for the power connections. The
