and fuses.
Inside the controller cabinet, 120VAC and 110VDC output buses are presented at the lower left
corner of the iBox as shown in the illustration below.
4. Measure from any #2 bus terminal to a Common (#1) terminal and verify 120VAC (+/-
10%).
5. Measure from any #3 bus terminal to a Common (#1) terminal and verify 110VDC (+/-
10%).
Power for PC board circuitry is provided through a 5-position, pluggable connector on the right
side of the iBox (near the Computer and Drive Reset buttons) as shown below.
6. Measure from each of the voltage terminals to GND to verify -15VDC, +15VDC, and
+5VDC respectively (+/- 2%).
Note
If any bus voltage is missing, check the associated fuse. The fuses are labeled with the bus num-
bers and are located at the top and bottom of the iBox.
