5.1.1Mounting the BM85
BM85 models are available for mounting on a horizontal shelf or vertical panel, or for installation into a standard 19 inch rack. Install your unit using the guidelines in Section 5.1.2 (for shelf or panel mounting) or 5.1.3 (for rack mounting).
The BM85 has a set of LED indicators to show its operating status. Your choice of a mounting method should include proper access for observing these indicators.
You should also provide access to the unit's rear panel for setting the switches, connecting the cables, and servicing.
Caution:Do not connect the BM85 into your application environment unless you have set its internal configuration. Do not connect it to your network or to any device unless you have set its switches properly for configuring or running.
See the Specifications Sections 1.6 and 1.7 for details about the BM85 operating power, environment, and connector requirements.
