Removing and Replacing an AC Power Supply
• TEMP (yellow)—Indicates that the power supply is in an overtemperature
condition, causing a shut-down to occur.
Note If the temp indicator is on, the fault indicator also goes on.
– Verify that the power supply fan is operating properly.
– Verify that the blower modules are operating properly.
– If the power supply fan and blower modules are operating properly,
replace the existing power supply with a spare.
• TEMP (flashing yellow—2500 W PEM only)—Indicates that a power supply
fan is locked or malfunctioning.
Note If the temp indicator is flashing, the fault indicator also goes on.
– Check to see if the fan is operating. Remove any obstructions to the fan.
– If the fan is not operating, replace the power supply.
• ILIM (2000 W PEM only) (yellow)—Indicates the power supply is operating
in a current-limiting condition.
– Each power cord should be connected to a dedicated AC power source.
Each AC power supply operating in the nominal range of 200 to 240 VAC
