Alarm
information

The isolation
transformer does not
have an
overtemperature or
ultra overtemperature
alarm.



The monitoring unit
reports an overtemperature
alarm for the isolation
transformer. If the alarm is
generated repeatedly
within one week, you are
advised to check for a fan
fault onsite.



The monitoring unit
reports an ultra
overtemperature alarm for
the isolation transformer.
You need to check onsite
immediately and clear the
alarm.

Fan

Visual
observation

Dust does not
accumulate on the
fan.

Clean the dust.

Visual
observation and
listening

The fan is intact, and
the rotation speed,
noise, and vibration
are in normal ranges.

Replace the fan.

Appearance

Visual
observation

The paint or
electroplated coating
on the cabinet is
intact.

Repaint and repair the
enclosure.

Grounding

Visual
observation and
using a tool
such as a
screwdriver or
wrench

The ground point is
properly connected to
the equipment room
ground bar.

Secure the ground point or
replace the ground cable.

7.2 ICC Routine Maintenance
