Cable Connections
Joystick Override Cable Installation—
A user fabricated cable, external switches,
and a 9-pin subminiature D connector with 4-40 jackscrews are required to
implement the joystick override. The cable needs to be shielded, with the shield
connected to the metal connector shell (see
Figure 2-50 ).
Power Supply Installation—
The Remote Aux Panel Power Supply
( Figure 2-51 ) should be securely fastened either on a horizontal surface where it
will not be disturbed, or attached to a support inside the equipment rack. Verify
that the power supply cord will reach the Remote Aux Control Panel and the AC
source. The power supply requires 100–120 VAC or 200–240 VAC and
automatically switches to select one of these two line voltages.
