Cause
Corrective Action
•
Does the cabinet operate correctly after resetting the circuit breaker? If it does not
Proceed to the next step.
Improper
connection
•
Measure AC voltage between LIVE (RED) and NEUTRAL (BLUE) terminal blocks inside
electrical box. See Figure 1-2.
•
Voltage must be within ± 10% of the rated voltage.
•
Refer to cabinet Serial Number Tag for required voltage.
•
If the voltage is out of the range or there is no voltage, check cable connection on
both sides of connector A. See Figure 1-3.
o
230 VAC at Connector A pin 1 and 3. Pin 5 is ground.
o
115 VAC Connector A pin 1 and 3. Pin 5 is ground.
•
If there is voltage at Connector A but no voltage is measured at the RED (LIVE) and
BLUE (NEUTRAL) terminal blocks, the problem is between connector A and the
terminal strips.
•
If voltage is not present at connector A, but voltage is measured at the female
connector for the line cord at the top of the cabinet that the power cord is plugged
into, the problem is between the female connector and the pins on Connector A.
Defective power
supply – Switch
Mode Power
supply (SMPS)
(Only when SMPS
(item code
1080945) is
installed)
•
Locate the SMPS (Power Supply) and Terminal block.
•
On the side of terminal block, measure the DC voltage between Red (pin 3) and Black
(pin 4) Measure on the side away from the SMPS.
•
The voltage should be in range of +12 VDC ± 10%.
•
If you do not have voltage, measures the other side of terminal block.
•
If out of range or no voltage, check incoming power to the SMPS – check terminal
where the cord is connected. The input of SMPS should be ±10% of the cabinet
incoming voltage.
