AQU244 and AQU128 Multiple Output, Off Line Supervised Power Supply/Chargers
Installation Guide
The AQU244 and AQU128 Supervised Power Supply/Chargers with standby battery(s) provide an uninterruptible
24vdc or 12vdc power source. The PDB-8C Power Distribution modules provide 8 or 16 class II power limited
outputs, each with 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 Line voltage, 90 to 240vac 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.
4. Use Power Service Switch to remove all output power. (No service switch on European models )
5. Connect DC devices to the Output Terminals ( * ). (-) Negative power is the bottom row of terminals marked
common 1 – 8. (+) Positive power is the top row of terminals marked 1 – 8. These terminals are just under the
green status LED’s. Each (+) terminal is protected with a PTC circuit breaker. Observe polarity.
6. You may connect a maximum of 2 outputs in parallel to double output current for a branch and still keep the
class II power limited classification. The power table below shows the continuous current you may use for
each output.
7. Be sure that the total current requirement conforms to the total available output current.
8. Connect Power Trouble alarm contacts.
9. Use Power Service Switch to restore output power.
10. Each Output Power/Fuse ready is indicated with a Green LED ON below each Circuit Breaker. See
instructions for more details regarding LED indicators.
11. To reset a tripped PTC Circuit Breaker, you may have to turn power switch off, or remove faulted circuit output
for up to 2 minutes. This allows the PTC re-settable fuse to cool and reset to it's normal “ON” condition.
