3. Make sure the sealing gasket is properly positioned on the terminal.
This gasket forms a compression type seal (NEMA Type 4x), do not
use sealing compounds.
4. Place the 6180 Computer in the panel cutout aligning the studs with
the mounting holes. The 6180 Computer will snap into the panel as
the temporary retaining tabs lock against the panel (see note
following).
Note:
Versions of the 6180 Computer designed for panel
mounting have metal tabs that temporarily lock the 6180
Computer against the panel. These tabs only facilitate
installation of the mounting hardware. The tabs are not
designed to provide permanent mounting.
5. Install the 18 self–locking nuts hand tight.
ATTENTION: Tighten mounting nuts to a torque of 10
inch pounds (10 inch–pounds, 1.1 N•m) to provide a
proper seal and prevent damage to the 6180 Computer.
Allen–Bradley assumes no responsibility for water or
chemical damage to the terminal or other equipment
within the enclosure because of improper installation.
6. Alternately tighten the self–locking nuts (use 3/8 inch socket) until
the 6180 Computer is held firmly against the panel (see
recommended tightening sequence below). The studs have an
integral spacer that prevents the gasket from being over–compressed.
The amount of torque required increases significantly as the gasket
reaches the proper compression. Tighten nuts to a torque of 10 inch–
pounds (1.1 N•m).
