Wiring Specifications and Procedures
Power Requirements and Battery Backup
The Eagle power quality recorder operates on voltages from 60 to
600Vac, 47-63 Hertz.
Recorder Operating Power Connection
Power connections to the Eagle are made by applying 60 to
600VAC between the Channel 1 and common voltage input
banana jacks. This will automatically charge the batteries
(batteries may take up to 14 hours to fully charge) and will power
the recorder.
Batteries and Power
When installed, the Eagle powers itself from the line voltage on
Channel 1 and requires less than 1.5 watts. This means that the
Eagle does not contain large internal batteries that must be
recharged or replaced, and it can be retrieved from the field,
downloaded, and reinstalled elsewhere minutes later. A small,
rechargeable NiMH ride-through battery powers the unit for up to
2 hours during a power outage while the Eagle is in record mode.
This battery should be replaced (by PMI only) every three to five
years, depending on recorder use. The internal lithium memory
backup battery allows the Eagle to retain recorded data or an
initialization setup for up to three years. This battery should be
replaced whenever the battery voltage as reported by either
ProVision or WinScan is 2.3V or lower. The ride-through and
backup batteries are contained inside the sealed enclosure and
are thus not user replaceable. Replacement of these batteries
should only be performed by PMI.
Installing the Recorder
This section explains the physical installation of the Eagle power
quality recorders. Installing the Eagle is not difficult for a
professional who is familiar with similar equipment. However, the
same care that is required when working with any high-voltage
