Troubleshooting and Error Indications
The EPS-3000P detects and reports several events and conditions that are considered errors. The EPS-3000P
will stop any run in process and display “ERROR XX” where XX is one of the below listed errors. When the EPS-
3000P is displaying an error indication, press the gray ON/OFF key to clear the error and return to setup mode, or
press the Run key to resume the run (after correcting the cause of the error). Note that loss of AC power during a
run is considered an error condition. Always stop a run before turning off AC power to the EPS-3000P.

Before servicing the unit, be sure to always turn off AC power using the switch at the rear of the
unit, and then disconnecting the AC line cord. The EPS-3000P power supply requires no periodic
servicing and should provide years of trouble free operation. Should you need to replace the fuses
proceed as follows:
Replacing a fuse
CAUTION: The EPS-3000P uses double pole neutral fusing.
Turn off AC power using the switch at the rear of the unit, and then disconnecting the
AC line cord. Remove the fuse holder assembly using a small flat blade screwdriver.
Always replace both fuses with appropriate replacement fuses: 5A, 250V, 5X20mm, type
T fuse (T5A,250V) (catalog number FB-FUSE-3).
