Power cables must not be routed over the indicated area.
Otherwise they
may interfere with the proper operation of sensitive electromagnetic compo-
nents located underneath.
The +15V supply should only be used with the speed sensor and not to power
any other external systems.
A
4-pin
low power connector is provided for an optional programmer. A com-
plete handheld programmer kit, including the appropriate connecting cable
with mating connector, can be ordered from Curtis:
p/n 168961101 for the User Programmer (model 1311-1101)
p/n 168962101 for the OEM Programmer (model 1311-4401)
.
If a handheld programmer is already available (such as the now discontinued
1307) but has an incompatible cable, the appropriate connecting cable can be
ordered as a separate part:
p/n 16185
.
If a 1314 PC programming station is used, the 1309 interface box and cable
connect the computer to the controller:
p/n 117465704 1314-1101, 1314 PC Programming Station (User) CD-ROM
p/n 117465707 1314-4401, 1314 PC Programming Station (OEM) CD-ROM
p/n 16994001 1309 Interface Box
p/n 16185 Molex cable for 1309 Interface Box
.
High Current Connections
Five tin-plated solid aluminum bus bars are provided for the high current con-
nections to the battery
(
B+
and
B-
)
, the motor armature (
M-
), and the motor
field
(
F1
and
F2
)
. These bus bars incorporate threaded mounting studs designed
to accept mounting bolts. This simplifies the assembly and reduces the mount-
ing hardware necessary for the power connections.
