Attack Bushing Cap
If this module will be mounted in the same enclosure as the
Intelligent Power Supply Unit (IPSU), an anti-attack bushing cap
covers a rear tamper spring. It fits inside an O-ring bushing
located in the enclosure’s rear wall anti-tamper spring knockout.
Leave the O-ring bushing and cap in place if the rear tamper is not
used.
1.
Remove the cap with the edge of a flat screwdriver.
2.
Discard the cap.
The tamper spring can now move freely through the bushing
and make contact with the enclosure.
3.
Secure the enclosure to the mounting surface.
