Installation

3.3 CAB-4 Series Cabinet

This section provides instructions for mounting the CAB-4 Series backbox to a wall. Follow these guidelines when mounting the back-
box:
Locate the cabinet backbox on a surface that is in a clean, dry, vibration-free area. The top should be located so that all operational but-
tons, switches, displays, etc. are easily accessible and/or viewable to the operator - usually no more than 66 inches (1.7m.) above the
floor. Allow sufficient clearance around the cabinet for the door to swing freely, and for easy installation and maintenance of equipment.
• Use the four holes in the back surface of the backbox to provide secure mounting (See Figure 3.1).
• Mount the backbox on a surface that is in a clean, dry, vibration-free area.
