3.1 Installation
Installation consists of mounting the 948B-1-5 Rack Chassis and the installation and termination of
electrical connections to the 956A-201-S1 UDR Simulator and S14283A101 Action Pak signal converter.
Refer to the standard manuals in Appendix D for connector assembly instructions and Loop Diagram
S157033A-106 in Appendix A for electrical termination. Prior to connecting terminated cabling to the UDR
Simulator or applying AC power, perform a point-to-point wiring verification per Loop Diagram S157033A-
106.
The 948B-1-5 Rack Chassis is designed to be installed in a cabinet equipped with standard EIA mounting
frames or surface mounted through a solid panel of sufficient gauge to allow for tapping of the 10-32
mounting holes. It is recommended that the rear of the rack chassis also be supported. The 948B-1-5
Rack Chassis is supplied with mounting hardware consisting of #10-32 oval head screws and nylon
washers with dress covers. Other equivalent mounting hardware may be used at the discretion of the
Customer.
Customer 120 VAC, 60 Hz power is connected to J3 of the 956A-201-S1 UDR Simulator and to terminals
1 through 3 of the S14283A101 signal converter. The nominal power requirements for UDR Simulator and
signal converter are 30 watts per channel.
Customer signal connections are made at J6 of the UDR simulator, signal converter terminals 5 and 6
(input) and signal converter terminals 7 and 8 (output) Relay contacts are available on UDR Simulator P1.
Shielded, twisted pair 22-20 gauge cable is recommended for signal wiring. Refer to Loop Diagram
S157003A-106 for details.
A full complement of mating connectors is provided with the 956A-201-S1 UDR Simulator but not all of
these will be required for installation. A pin extraction tool must be used when removing pins from the
AMP connector used for AC power input. The P6 signal input plug for J6 is a 26 pin, solder type
connector. It is recommended that heat shrinkable or other insulating tubing be used on the P6
connections after soldering due to the close spacing of the pins. Tool # 305183 is provided as part of the
connector kit.
Connection to the S14283A101 signal converter should be made using insulated barrel crimp type, 22-18
AWG lugs suitable for a #6 to #8 screw.
When terminating UDR Simulator rear panel cables, allow sufficient service loops in these cables to allow
the UDR Simulator to be withdrawn from the front of the rack chassis for cable disconnection.
