The Alpha CFR is designed to be easy to use and extremely flexible. The
CFR’s interchangeable front panel interface devices provide you with a wide range
of information management options. The rear panel accepts a variety of connectors
and receptacle plates to facilitate your most demanding communication and powering
needs.
2.2 The CFR Front Panel
The CFR front panel comes equipped with a Standard Interface Device
(SID), or an optional Intelligent Interface Device (IID), to display vital UPS operating
parameters. The front panel can be easily removed for service or battery access
by loosening the two screws located in the lower grill.
