Installation
1. Install the desired transformer as shown in the diagram above. The Power Supply must use a dedicated
transformer. Do not share a transformer being used by another power supply.
2. To provide power during a power failure, connect the desired backup battery (verifying proper polarity), then select the appropriate battery charge current (350mA or 700mA) using the “Charge Current” jumper.
3. To conduct a “local” battery test, connect the Power Supply’s “TST” input to the “-” terminal of the Power Supply. The output supply will drop by 25% if the battery cannot supply adequate power.
4. Connect the required load to the “+” and “-” terminals of the power supply.
