or non-jumpered caps. However, the presence of
special circuit caps prevent the test probe from
making contact with that specific pair.

clamps enough to allow clearance over the cap heads.

9.0 Protector Installation and Testing
a.
If the terminal is equipped with a cover over the protector field, loosen the captive screw(s) and open the
cover.
b.
Fully insert the appropriate UL Recognized or Listed protection device into the protector receptacle field.
Refer to section 3.0
Important:
All protectors must be fully inserted during testing.
Standard protector jack field pin configurations are
used with the central grounding pin serving to
polarize the module. A pair of long pins on each
module connect TIP and RING to the entrance
cable side while shorter pins connect to line side.
Detents on the longer pins hold the protector in
place when it is pulled out to an intermediate
position to disconnect the line. When in this
position, the entrance cable side continues to be
protected.
c.
Once all protectors are in place, close protector field cover and secure.
