Connect the power source to the main unit through the conduit opening located on the
bottom of the main unit. Fasten the power wires to the appropriate screw terminals as
shown. Do not exceed 13 in-lb (1.5 Nm) of torque when tightening.
As power is initially applied to the System-10, immediately confirm that the display is
illuminated and scrolling through the character diagnostic test. The test will begin by
indicating the letter P in every position followed by a countdown from 9 to 0 for each digit,
If this does not occur, disconnect power immediately and re-verify all wiring connections. If
the problem persists, contact ONICON.
