CAUTION When connecting the power supply, voltage
polarity is extremely important. Applying power
with incorrect voltage polarity could damage the
power supply and the BUC 102. Identify the power
cord negative (ground) lead by the ridges on the
side of the cord or a black heat shrink wrapping
around it.
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
To verify the polarity before connection, check the no load
power supply output with a voltmeter.
Your BUC 102 may have shipped with a blue captive
screw connector. This blue connector can be plugged
into either a blue or an orange power receptacle.
The ideal length of exposed (stripped) copper wire
for the blue connector is 3/16" (5 mm).
