lock the ground and test device in the
“CLOSED” position. Key KCF is now captive
and key KB is released (Figure 3, r) .
10. Transfer key KB to key lock K4 (Figure 3, h) .
Rotate key KB, electrically and mechanically
locking the ground and test device in the
“CLOSED” position. Key KB is now captive
and key KD is released.
11. Transfer key KD to key lock K5 (Figure 3, b) .
Rotate the KD key to unlock the test port
shutters. Key KD is now captive.
12. Open the test port shutters using the slide
