Console Installation
158 025-9533Y
A mating power connector is provided in the rack-mount panel’s accessory bag for users
who prefer to use their own power supply. The power pin connections are listed in Table
64 .
Table 64: Primary Power Pin Connections
A console is equipped with an internal fuse. This is labeled “F1” on the control board near
the input power connect. The fuse is accessible by lifting the top cover of the unit. If
replacement is required, replace only with 2.5-ampere, slow-blow, AGC-type fuse.
Model 4018 Auxiliary Power
A connection for auxiliary power for the Model 4018 is also provided in the unit. Screw
terminal connector J16 is used to c12 V
DC
and ground. The specifications for the
auxiliary DC voltage are the same as for the main power supply. However, the voltage
level must not exceed the main supply by more than 2.5 V
DC,
or drain on the auxiliary
supply may occur. The auxiliary supply is automatically connected when the primary
voltage falls more than 3.5 V
DC
below the auxiliary supply.
Connection to the auxiliary is made through the wiring access hole in the back of the unit.
The 3-position screw terminal strip J16 is used for connection and AWG #18 stranded
wire is recommended. Strip the ends of the wire back ¼ inch, insert into J16, and screw
down the terminal. The position nearest the first channel card slot (Pin 1) is positive, and
the center terminal and terminal nearest the side of the console (Pins 2 and 3) are negative.
CIC Card Power Supply Test Points
The Console Interface Cards have three test points on the faceplate of the card related to
power supplies on the CIC card. These test points are marked as +5 Vdc, GND, and -5
Vdc. In May of 2003, the voltage regulator for the minus supply was changed to -3 Vdc;
however, the silkscreened label on the front panel remained -5. If your CIC card -5 Vdc
test point reads -3 Vdc, there is no problem.
Model 4219 Power Connection Strain Relief
A strain relief has been provided in the parts bag for the Model 4219 to prevent the power
cable from being accidentally being pulled out of the jack on the rear panel of the unit.
