External Power
The monitor (and EMU) also can receive power from an external
DC power source. All external power to the monitor comes through
the EMU and is delivered to the monitor via the Communication
Cable (ADS p/n 106227). The EMU contains protection circuitry
that limits the amount of power that can reach the monitor. The
internal monitor and EMU battery packs must be removed prior to
connecting the units to external power. External power eliminates
the need for periodic battery pack replacement and disposal. For
more information, refer to Chapter 5, External Power.
Note:
Although no longer sold, the Rechargeable Battery
Pack (RBP - ADS Model 3600RBP) can be connected
directly to the 5000-IS1 or connected via the approved Y
cable.
Warning: With the exception of the RBP noted above,
under no circumstances can the monitor receive external
power directly. Attempting to power the monitor without
an EMU will void the warranty and potentially create an
unsafe operating condition in hazardous areas.
