ATTENTION
To avoid driving the first of two paralleled power
supplies into an overcurrent condition that would
shutdown the module, you must simultaneously
turn on both power supplies.
The power supply module has a green indicator light (labeled P/S
ACTIVE). It indicates the operating condition of the module, and
can be used for diagnosing faults.
The module monitors itself for:
•
overvoltage
•
undervoltage
•
overcurrent
Any of these conditions will shut down the power supply. Following
a shutdown, turn the power supply off for at least 15 seconds (-P3
and -P4) or 45 seconds (-P5 and -P5E) before you turn it on again.
