Selector switch and the padlock provisions.2.4.5 Lock #5 (key KD)The Lock #5 interlock is a single cylinder lock used to open and lockthe test port shutters. When rotated, key KD moves the lock pin intothe locked and unlocked positions. Key KD is normally in Lock #4and is available for use in Lock #5 only when the 38 kV SEG&TD islocked “Closed-Grounded”.Key KD is removable from Lock #5 in two extended bolt positions.One position is when the Test Port shutters are closed (see Figure20). The second position is when the Test Probes are inserted in theTest Ports and they are being retained by the “detent” position ofthe shutter (see Figures 21 & 49).Figure 20. Test port shutters in the closed position.Figure 21. Test port shutters retaining the test probes.3 Operation (Lower SEG&TD)3.1 Safe practices WARNINGTHE 38 KV SEG&TD IS A SAFETY-RELATED DEVICE. IT MUST BERECOGNIZED THAT IMPROPER USE CAN RESULT IN DEATH, SERIOUSPERSONAL INJURY, OR PROPERTY DAMAGE. THAT IS WHY IT ISIMPORTANT THAT THE USER DEVELOP SPECIFIC AND SAFE OPERATINGPROCEDURES FOR ITS USE.The following general safe practices are recommended.1. The 38 kV SEG&TD cannot be stored in a switchgear compart-ment. It can only be stored in its storage compartment. CAUTIONDO NOT STORE THE 38 KV SEG&TD IN THE SWITCHGEAR COMPARTMENT.2. Store the 38 kV SEG&TD in a clean, dry area free from dust,dirt, moisture, etc.3. Keep all insulating surfaces, which include primary support insu-lation and insulation barriers, clean and dry.4. Check all primary circuit connections to make certain that theyare clean and tight.5. Permit only authorized trained personnel to use this device.6. Take extreme care while using this device to avoid contacting“Live” or “Hot” (energized) terminals.7. Do not remove the 38 kV SEG&TD front panel while using thisdevice.8. Always “Close” the grounding 38 kV SEG&TD electrically fromthe farthest distance with the remote control switch.9. Check for dielectric vacuum integrity at 60 kV AC across the ter-minals to ground with the grounding 38 kV SEG&TD “Open”.3.2 Operating the 38 kV SEG&TD using the five interlocks3.2.1 Initial 38 kV SEG&TD condition and interlock positionsWhen delivered, the following should be true of the 38 kV SEG&TD(Refer to Table 2).otee:N If any of these initial conditions and/or interlock positions is incorrect,contact your Eaton Representative.1. The 38 kV SEG&TD is in the “Open” position (showing 38 kVSEG&TD open indicator as shown in Figure 22).2. The Selector switch is set to “Off”.Figure 22. “Open” indicator and the selector switch in the “Off”position.Breaker openindicatorSelector switch in the“Off” position
