Intelligent Interface Device (optional)
The Intelligent Interface Device (IID) option is available either as a
replacement of the Standard Interface Device (SID) or as a desktop unit for remotely
accessing the unit (up to 2000 ft.). The desktop unit comes with an optional modem
for accessing the UPS information via a telephone line. The IID front panel provides
precise UPS information and guides you through the various menu options which
include Ambient Battery Temperature, Input Voltage and Current, Line Frequency,
Output Voltage and Current, Power in Watts, Power Factor, Battery Voltage, Charger
Status, and more. The History Log maintains an on-going record of UPS alarms
and power anomalies by time, date and type of occurrence. Whenever a UPS
alarm condition occurs, such as Line Failure, Low Battery Warning, Low Battery
Shutdown or Service, it is displayed by the front panel indicators and recorded in
the History Log.
For further information on operation and installation of the IID, please refer
to its operator’s manual, “Information Management Using the Intelligent Interface Device.”
External Modem (optional for SID eqipped units)
An optional, customer supplied external modem provides access to the
unit via a phone line. Service personal can dial up the unit to remotely monitor,
control, and calibrate the unit. On specified alarm conditions, the unit can dial an
emergency number to notify the system manager via modem of the alarm. The
modem option may also be used to page service personnel on critical alarm
conditions.
NOTE: The CFR1500 and CFR 1500RM do not support the modem option
with an IID.

Battery Testing
To determine the maximum amount of battery run time available, run this
test at least once a year. The length of the test can vary from several minutes to
many hours and should not be done during critical applications. Since the test
discharges the batteries, backup power may not be readily available (for several
hours) in the event of a utility power failure.
1. Unplug the AC line cord from the wall receptacle. The front panel “LINE
FAILURE” LED will come ON. Make a note of the START time.
2. When the CFR reaches LOW BATTERY WARNING, record the time.
Subtract the START time to determine the actual safe run time. To cancel
the test, plug the AC line cord back into the wall receptacle.
3. To determine the reserve time available, allow the UPS to continue until it
reaches LOW BATTERY SHUTDOWN. WARNING: This will cause the
load to go down. Make a note of the time. Subtract the LOW BATTERY
WARNING time to determine your available reserve time.
4. Switch the load OFF. Plug the AC line cord back into the wall receptacle.
The “LOW BATTERY WARNING” LED will remain ON until the batteries
are partially recharged. Switch the load ON, one device at a time. To
determine recharge time, subtract the time you resumed LINE PRESENT
operation from when the “LOW BATTERY WARNING” LED goes OFF.
