AQU126, AQU126-8C, AQU243 and AQU243-8C Supervised Power Supply/Chargers
Installation Guide
The AQU243 and AQU126 Supervised Power Supply/Chargers with standby battery(s) provide an uninterruptible
24vdc or 12vdc power source. The DC output of AQU243 and AQU126 power supply module is not power limited.
The 8 DC outputs of AQU243-8C and AQU126-8C are class II power limited outputs, each with PTC circuit breaker
protection. Keep ¼” minimum spacing between non power limited and power limited wiring.
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. For AQU243 and AQU126single output units. Connect DC devices to the Output Terminals. Not power limited.
Observe polarity.
4. For AQU243-8C and AQU126-8C multi-output units connect DC devices to the output terminals on the PDB-8C
board. (-) 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 LEDs. Each (+) terminal is
protected with a PTC circuit breaker. Observe polarity. These outputs are Class II Power Limited.
5. The power table below shows the continuous current you may use for each output.
6. Be sure that the total current requirement conforms to the total available output current.
7. Connect AC FAIL alarm contacts. N/O means normally open with AC ON.
8. Connect LOW BAT alarm contacts. N/O means normally open with battery voltage normal.
9. Connect Line voltage, 90 to 260vac 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.
(L= line), (N=Neutral), and (G=Ground)
10. To reset a tripped PTC Circuit Breaker, you may have to correct 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.

The DC outputs of the AQU243-8C and AQU126-8C
are class II power limited. The output on the AQU243
& AQU126 is not power limited. Dress wires to keep a
minimum space of .25” between non-power limited and
power-limited circuits.
