3.4. Mount OIT to Panel
STEPS
1. Gently position the OIT with the studs through the panel mounting holes.
2. Secure the OIT by installing the four #6-32UNC mounting nuts using a
5/16 inch socket wrench or nut driver.
CAUTION: Do not torque the 4 mounting nuts to over 15 pound-inches. Over
torquing can strip the threads or pull the studs loose.
RE-INSTALLING: Because the gasket will take a “set” to the panel, be sure to
re-install any OIT to the same panel cutout when a NEMA 4/12 seal is required.
