Section 2 - Installation

Mounting

Refer to the PCC-IV Mounting and Panel Cutout Dimension drawings that follow. Cut the hole in the enclosure.
Remove any burrs and loose metal chips. Remove the Panel Mounting Brackets from the PCC-IV case. Slide the
PCC-IV into the hole. From the rear of the PCC-IV, slide the Mounting Brackets tabs into the slots in the PCC-IV
case. Using a 1/8” Allen wrench, tighten each mounting bracket screw against the enclosure.

Additional Mounting Brackets can be ordered as part number 190347, if the mounting brackets supplied with the
PCC-IV are lost or damaged.
