AQU243-4F (&-8F) and AQU126-4F Multiple Output, Off Line Supervised Power Supply/Chargers
Installation Guide
The AQU243-4F (&-8F) and AQU126-4F Supervised Power Supply/Chargers with standby battery(s) provide an
uninterruptible 24vdc or 12vdc power source. The DC power outputs are class II power limited outputs, each with
PTC circuit breaker protection.
1. This installation should be made by a qualified service person, should conform to all local codes and should
comply with The National Electrical Code (or equivalent).
2. Mount the Power Supply in desired location.
3. Connect DC devices to the Output Terminals. Observe polarity.
4. The power table below shows the continuous current you may use for each output.
5. Be sure that the total current requirement conforms to the total available output current.
6. Connect AC FAIL alarm contacts. N/O means normally open with AC ON.
7. Connect LOW BAT alarm contacts. N/O means normally open with battery voltage normal.
8. Connect Line voltage, 90 to 250vac and Earth Ground to the 3 position terminal block marked HIGH VOLTAGE.
The Earth Ground terminal is connected to the enclosure and outer heat sink case for safety and EMI filtering.
9. Each Output Power/Fuse ready is indicated with a Yellow LED ON centered above each output terminal pair.
See instructions for more details regarding LED indicators.
10. To reset a tripped PTC Circuit Breaker, you may have to correct the fault and remove load for up to 1 minute.
This allows the PTC re-settable fuse to cool and reset to it's normal “ON” condition.
