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.

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.
