2.4.5 Lock #5 (key KD)
The Lock #5 interlock is a single cylinder lock used to open and lock
the test port shutters. When rotated, key KD moves the lock pin into
the locked and unlocked positions. Key KD is normally in Lock #4
and is available for use in Lock #5 only when the 38 kV SEG&TD is
locked "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 Figure
20). The second position is when the Test Probes are inserted in the
Test Ports and they are being retained by the "detent" position of
the shutter (see Figures 21 & 49).

3 Operation (Lower SEG&TD)
3.1 Safe practices
 WARNING
THE 38 KV SEG&TD IS A SAFETY-RELATED DEVICE. IT MUST BE
RECOGNIZED THAT IMPROPER USE CAN RESULT IN DEATH, SERIOUS
PERSONAL INJURY, OR PROPERTY DAMAGE. THAT IS WHY IT IS
IMPORTANT THAT THE USER DEVELOP SPECIFIC AND SAFE OPERATING
PROCEDURES 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.
 CAUTION
DO 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 they
are 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 this
device.
8. Always "Close" the grounding 38 kV SEG&TD electrically from
the 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 interlocks
3.2.1 Initial 38 kV SEG&TD condition and interlock positions
When delivered, the following should be true of the 38 kV SEG&TD
(Refer to Table 2).
N otee: 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 kV
SEG&TD open indicator as shown in Figure 22).
2. The Selector switch is set to "Off" .
