S Check if dust or dirt is accumulated on the heat sink.
S Check if dust is accumulated in the air vents.
S Check if the appearance is normal.
S Check
if the cooling fan for the control panel operates normally
. Check for noise or error vibration,
and
also check if
the total hours of operation have exceeded the value shown in the parentheses.
D Regular Parts Maintenance
The
Inverter consists of many dif
ferent parts. Full performance is possible only when these parts oper
-
ate normally.
Some
electronic parts require maintenance depending on the service conditions. T
o allow the Inverter
to
operate normally over an extended period of time, always perform regular inspection and parts re
-
placement according to the service life of each part.
Regular
inspection intervals vary according to the Inverter installation environment and service condi
-
tions.
The
maintenance intervals for this Inverter are shown below
. Use this information as a guide to regular
maintenance.
The standard intervals for regular maintenance are as follows:
S Cooling fan: 2 to 3 years
S Electrolytic capacitor: 5 years
S Fuse: 10 years
As for service conditions, it is assumed that the ambient temperature of the Inverter is 40°C, and the
Inverter
is used at a load factor
of 80% for eight hours a day and is installed as specified in the Operation
Manual.
To
extend maintenance intervals, ambient temperatures should be lowered and power-ON time should
be minimized.
Note Contact your OMRON representative for the maintenance procedure.
