4.2 Installing the Power-Ring Converter
Two options are available for powering either a battery module or subscriber’s NID/NIU/ONT: the
Power-Ring Converter (for power from the meter) and the Home Converter (plugs into a standard AC
utility outlet).
NOTE:
Prior to powering the converter, verify that the NIU/NID is properly grounded and connected to either
the 12V Lead (pin 2) of the battery module, or the Return Lead (pin 1) of the Power/Home Converter.
The FlexPoint AX does not make contact with Earth Ground through the meter socket; Earth Ground is
provided by connection to the NIU/NID. Prior to connection to the NIU/NID Earth Ground, the FlexPoint AX
output fl oats and may have enough leakage current to cause any one of the output leads to measure high
voltage with reference to Earth Ground. The energy represented by the high voltage does not represent a
safety hazard, but may cause a slight undesirable tingling sensation.
CAUTION!
Improperly connecting these wires will result in equipment damage or non-operation of the unit.
NOTE:
The converter can be installed at the same time as the Power-Ring, or at a later date. Refer to NOTE in
Section 2 on wire size and distance.

The FlexPoint AX system sets an alarm during an AC line
outage or brownout and if the AC supply voltage is insuffi cient
to maintain battery charge. In order to prevent nuisance alarms
and consequent service disruptions, the FlexPoint AX system
monitors the battery status and sets the alarm when the battery is
discharging. Depending on load conditions, this may take a few
minutes. Conversely, the alarm is cleared when the battery again
receives consistent charge. Please note that this algorithm will also
indicate an alarm when AC is present, but the system is overloaded
to the point where the battery is required to supplement the power
supply to satisfy the load current requirement. If an AC fail alarm is
indicated despite a solid AC line voltage, check if the load is within
specifi cation and if the lead lengths and wire sizes are per the table
in the installation instructions.
The unit will automatically initiate battery test approx. 30 days after
last signifi cant battery discharge (>10% of full energy charge). The
test lasts <30 mins. System notifi es for battery replacement if
voltage changes excessively during test.
Approx. 20 secs after battery removal, system detects for battery,
and repeats every 20 secs, to verify battery disconnection. After 5
seconds, system initiates Battery Missing alarm and maintains this
state until a valid battery (open circuit voltage >12.3V) is
reconnected to the system.
If battery voltage <11V ±100mV >5 secs, system initiates Battery
Low alarm.
This system is in overload, >120% of rated load.

4. How long must a battery be charged via trickle charge to reach 100% capacity?
24hrs to 100% capacity.
5. Does this unit have temperature compensation in the design? If so, what is the Voltage Per Cell
(VPRC) voltage?
It does, at a rate of -3.3mV/cell/°C or –19.8mV/battery/C from 0°C to +40°C. Maximum
charged voltage is 14.4V and minimum is 13.3V.
6. If I replace a battery when the replace battery LED is illuminated, why does the LED not go out?
Will the alarm reset itself?
When replacing a battery, it is necessary to wait approximately 20 seconds and allow the
"Replace Battery" LED to change from steady to blinking. Once the LED blinks, the
fully-charged replacement battery can be connected. The LED will go out, indicating the
alarm has been cleared, and the system will begin normal operation.

6. Frequently Asked Questions
7. If I replace a battery under a “no alarm” condition and the battery voltage was 12.6Vdc, and
an outage occurs and the battery voltage drops to less than 12.2Vdc, will this cause a “replace
battery” alarm, or will the unit try to recharge that battery until the next 40 day test?
No, the “replace battery” indicator will only be activated during the 40 day battery test
routine. Under normal operation, including power failure, the alarm is not activated. Under
these conditions the unit will try to recharge the battery until the next 40 day test.
8. Does the charger disconnect or “ramp back” when a replace battery alarm is illuminated? If not,
how does the unit prevent batteries from being cooked, which may cause a gas build up inside
the enclosure?
No. It will continue to charge the battery to the safe level per the battery manufacturer's
specifi cations. The enclosure provides adequate venting and minimal volume to keep
gas build-up from becoming a concern.
9. If I have a Power-Ring Converter (PRC) reading of 11.8Vdc on the output, is this unit considered
bad? What should be the voltage measured at the output of the device with no cable attached?
There is a high possibility that the voltage-controlled wire, between the battery unit and the
power supply, is not properly connected. Without the control wire, the power supply will only
put out a ~12V; 11.8V is pretty close to that voltage. If the connection is properly verifi ed, then
the unit may have a defective voltage regulation circuitry.
10. What is the line load regulation of the PRC?
Within the proper load, (no overload) the line load regulation of the PRC is excellent. It is
very tightly regulated since it provides the fl oat voltage to charge the battery.
11. Does this unit have a positive disconnect from the utility mains when operating under battery
conditions?
There is no physical disconnect from the main, and no chance for back-feed due to the High-
Frequency (HF) DC isolation transformer. Also, the unit is agency-qualifi ed under stringent
double insulation criteria for SELV (Safety Extra Low Voltage).
12. Does the green wire (control wire for the battery) have a readable voltage that means anything?
The functional voltage on the green wire could be any value between 0V to +4V, depending
on the battery condition and load. Therefore, it is not a very useful troubleshooting tool.
