4500-CILK-* Interlock Cable Keithley Instruments, Inc. 28775 Aurora Road User's Guide Cleveland, Ohio 44139 (440) 248-0400 www.keithley.com Introduction This document contains information on the 4500-CILK-* interlock cable. This cable is used to connect the 451x-QIVC card interlock circuits to a test fixture switch to inhibit source outputs when the test fixture lid is open. Connection precautions WARNING The interlock is required for safe operation. The test fixtures must ensure that the interlock circuit is disabled (source outputs inhibited) so that an operator is not exposed to any harmful conditions. Description Cable configuration The overall configuration of the 4500-CILK-* interlock cable is shown in Figure 1. The cable includes a 14-pin male con- nector that mates with the 451x-QIVC card interlock connector on one end, and a 9-pin D-sub female connector on the other end for connections to a test fixture.
