7.3.2 Poor Output Voltage Regulation
If the AC Power Source exhibits poor voltage regulation the following item may be at fault:
CAUSE
The Remote Sense lines are not
connected at the same point monitored by
the external voltmeter used for load
regulation check.
7.3.3 Distorted Output
CAUSE
Power source is grossly overloaded.
Input mains voltage is too low.
The crest factor of the load exceeds 3:1.
7.3.4 Unit Shuts Down After 3-5 Seconds
CAUSE
Output shorted.
Output grossly overloaded.
Operating load with too high inrush or start
up currents.
7.3.5 No Output and No Lights on Front Panel
CAUSE
Front panel power switched off.
No input power to the input connector.

SOLUTION
Connect AC voltmeter to Remote Sense
lines on the Rear Panel Power Output
terminal strip.
SOLUTION
Reduce load.
Verify at input terminal block that input
voltage is within specified limits.
Reduce load current peaks by reducing
load.
SOLUTION
Remove output short.
Remove overload.
Consult factory for application advice.
SOLUTION
Switch the breaker on.
Ensure correct input power.
