1. Mounting the Board Locate the unit inside a UL Listed NEMA 1 enclosure (such as a BASE LVPC Low Voltage Power Cabinet). Drill four
0.187" diameter holes (3/16”) to match the four corner holes in the printed circuit board. Push the nylon standoffs supplied into each hole and snap the
PCB module into place. Mounting with double-sided tape is not recommended.
2. Transformer Wiring Connect the appropriate Transformer input wires (black and white wires) to a 120VAC power source. Connect the two
Transformer output wires to the two Transformer ‘AC’terminals of the Power Supply.
3. DC Output Setup With the tip of a small screwdriver, set the DC Output Voltage switch for the desired output voltage - 12 or 24 VDC.Turn on the
120VAC power source. The AC and DC green LEDs will light. Next, measure the voltage at the DC Output terminals with a voltmeter. The output
voltage is factory set as shown in the table above. However, if a field adjustment is desired, use a small screwdriver to slowly adjust the output voltage
at the potentiometer labeled OUTPUT ADJ. Then turn off the 120VAC power source before proceeding with the installation.
4. Fault Supervision Setup Locate the 3 dip switches labeled FAULT SUPV.
SP/DC = Supervision Power / DC Output Supervision. This switch ON will enable the Fault Supervision relay and will enable monitoring
of the DC Output for short or low output conditions. If fault supervision is not required, place the SP/DC dip switch in the OFF
position. This will reduce the no-load current draw by approx. 40 mA.
AC = AC Input Power Supervision. This switch ON will enable monitoring of the AC Input for AC power loss or blown AC power
fuse. This switch will have no effect if SP/DC is OFF.
BATT = Battery Power Supervision. This switch ON will enable monitoring of the Battery Set for low battery, shorted battery or
reversed polarity hookup (blown battery fuse). Battery presence is not monitored. This switch will have no effect if SP/DC is OFF.
Turn this switch OFF if no battery will be used.

5. Fault Relay Ouput Terminals The Fault Relay Form-C contacts are rated at 2Amps. The terminals are labeled for when the relay is de-energized
(selected fault condition is present). The relay is normally energized when no selected fault condition exists. The ST terminal is a Spare Terminal and
is not connected to anything. It can be used as an easy splice point for an end-of-line resistor when monitoring the fault relay with a supervised circuit.
6. DC Output Wiring Connect output wiring to the DC OUTPUT terminals. Observe and verify correct DC polarity before powering the unit.
Incorrect polarity may damage user equipment. See table above for maximum DC output current.
Installation Instructions
* * * WARNING * * *
Turn off all power feeding the module terminals before installing, servicing or changing any switch settings, wiring or fuses.
Failure to observe this warning may cause electrical shock hazard or may damage internal or external circuit components.

7. Battery Wiring Connect battery wiring to battery terminals of the Power Supply first, then connect
other end to battery set. Observe and verify correct DC polarity before connecting battery set. Incorrect
polarity will blow the BATTERY FUSE. See table above for maximum BatteryAH. Only use recommended
battery type - Yuasa, Power Sonic or equivalent sealed lead acid or gel cell.
8. Power Up Re-check all connections and apply AC power to the unit.

Power System Design Tips
Power Supply Total Current Draw
Add the operating current ratings for each device to be powered to
determine the expected continuous operating current required. Do not
exceed the specified maximum output current. If the output current value
is exceeded, the power supply regulator may overheat. The unit has built-
in thermal overload protection and the DC output will turn off if
overheating occurs.
CableResistance
When powering devices over considerable distances, the cabling resistance
may be so high that the voltage available at the device has dropped to an
unacceptable level. To prevent this from occuring, system cabling should
be designed with adequate sized conductors.
Power Distribution
Separately fusing output devices or groups of output devices greatly
reduces trouble-shooting efforts when shorts or output device abnormali-
ties occur. The larger the power supply and number of devices powered,
the greater the need for power distribution. BASE has a variety of power
distribution, interface and control products for a wide range of output
devices.
The information in this manual is believed to be accurate in all respects. However, BASE Electronics
cannot assume responsibility for any consequences resulting from the use thereof. The information
contained herein is subject to change and BASE Electronics may issue a revision to incorporate such
changes at any time.
