Operation
Turn the power switch on the front of the unit on to energize the outputs.
To adjust the output voltage, turn off the power switch. Remove the plate from the top of
the box. Reach in with a non-conductive device such as a pencil and open or close the dip
switches as shown below to select the desired output voltage. Replace the plate. Turn the
power switch on.
Troubleshooting
If the load exceeds the continuous rating for too long a period, the internal temperature sensor
will cause the unit to stop boosting the input voltage until the unit has cooled down. After the
unit has cooled down, normal operation will resume.
If the input voltage drops below the specied minimum input, the unit will sound the alarm.
If the output voltage drops below the specied minimum, the unit will sound the alarm.
If the current demanded by the devices connected to the unit exceed the maximum current
rating, the fuse will blow.
If the fuse blows with no load connected, check that the power leads are connected to the
battery with the correct polarity; if they are then the unit is damaged and must be returned for
repair.
