Verification and Remedy to
the Indicated Error Codes
NOTE
The capacitors inside the power supply will slowly
discharged after you turn off the switch of the
power supply or the switch at the breaker box (dis-
tribution panel). Wait at least 5 minutes for the dis-
charge to complete and then remove the cases to
continue your inspection and repair (or mainte-
nance) inside the power supply. As for the removal
and installation of the case, Refer to section 11.1-1.
NOTE
During the "Verification/Remedy" procedures
below, follow the alphabetical sequence (a, b, c...)
and proceed with your verification and
confirm
ation.
NOTE
After you Verify and replace all spare parts and
components, verify that there are no damaged har-
nesses or connectors, uninstalled or loose screws.
2.1 E01 “Over-Temperature at the
primary side”
Cause
Occurs when an over-temperature condition of the
primary IGBT is detected.
Verification/Remedy
a) Unit may be in thermal shutdown mode.

Review the rated duty cycle of the unit per
section 3.8. Exceeding the duty cycle can
damage the unit and void the warranty. Refer
also to section 1.6 for additional information.
b) Verify the ventilating condition.

Maintain a clear and unobstructed distance
of more than 30cm in the front and more that
50cm in the rear of the unit for ventilation pur-
poses.

Verify and maintain clean, dust free, front and
rear airflow paths. Cleaning and removing
dust from the front and rear panels once
every six months in a normal working envi-
ronment is recommended. Extremely dusty
environments will require more frequent
cleanings.
c) Verify the operation of the cooling fan, FAN1,
and replace it if necessary.

Verify the condition of FAN1. Verify that there
are no broken or cracked fan blades and that
FAN1 is not producing any abnormal sounds.

If broken or cracked FAN1 blades, or abnor-
mal sounds are emanating from FAN1,
replace FAN1.

Refer to section 12.3-11 for additional FAN1
tests.

Refer to section 11.5-3 for the replacement of
FAN1.
d) Replace PCB4 (WK-5449) and PCB5 (WK-
5448).

Refer to section 12.3-4, 3-5 for the replace-
ment of PCB4 and PCB5.
2.2 E02 “Over-Temperature at the
secondary side”
Cause
Occurs when an over-temperature condition of the
secondary IGBT and diode are detected.
Verification/Remedy
a) Unit may be in thermal shutdown mode.

Review the rated duty cycle of the unit per
section Chapter 3.8. Exceeding the duty
cycle can damage the unit and void the war-
ranty.
b) Verify the ventilating condition.

Maintain a clear and unobstructed distance
of more than 30cm in the front and more that
50cm in the rear of the unit for ventilation pur-
poses.

Verify and maintain clean, dust free, front and
rear airflow paths. Cleaning and removing
dust from the front and rear panels once
every six months in a normal working envi-
ronment is recommended. Extremely dusty
environments will require more frequent
cleanings.
