2–12 Installation
Publication 6181-UM001D-EN-P
To install the RAC6181 Computer in a panel using 8 mounting studs:
ATTENTION: Disconnect all electrical power from the
panel before making cutout.
Make sure the area around the panel cutout is clear.
Take precautions so that metal cuttings do not enter any
components that are already installed in the panel.
Failure to follow these warnings may result in personal
injury or damage to the panel components.
To install the RAC6181 Computer in a panel using mounting studs:
1. Cut an opening in the panel using the appropriate panel cutout
dimensions provided on Page 2-9 (10.4 in. version) or Page 2-10
(12.1 in. version). Carefully drill eight 6.4mm (0.25in.) holes for the
mounting studs as indicated.
2. Make sure the sealing gasket is properly positioned on the terminal.
This gasket forms a compression-type seal (NEMA Type 4), do not
use sealing compounds.
3. Place the RAC6181 Computer in the panel cutout aligning the studs
with the mounting holes.
4. Install the 8 self-locking nuts hand tight.
5. Alternately tighten the self-locking nuts (use 3/8 in. socket) until the
RAC6181 Computer is held firmly against the panel (see
recommended tightening sequence below). The amount of torque
required increases significantly as the gasket reaches the proper
compression. Tighten nuts to a torque of 2.7 N-m (24 in-lbs).
ATTENTION: Tighten mounting nuts to a torque of 2.7
N-m (24 in-lbs) to provide a proper seal and prevent
damage to the RAC6181 Computer. Rockwell
Automation assumes no responsibility for water or
chemical damage to the terminal or other equipment
within the enclosure because of improper installation.
