D Periodic Maintenance of Parts
The Inverter is configured of many parts, and these parts must be operating properly in order to
make full use of the Inverter’s functions.
Among the electronic components, there are some that require maintenance depending on their
usage conditions. In order to keep the Inverter operating normally over a long period of time, it is
necessary to perform period inspections and replace parts according to their service life.
Periodic inspection standards vary depending the Inverter’s installation environment and usage
conditions.
The Inverter’s maintenance periods are noted below. Keep them as reference.
S Cooling fan: 2 to 3 years
S Electrolytic capacitor: 5 years
S Fuses: 10 years
The usage conditions are as follows:
S Ambient temperature 40°C
S Load factor: 80%
S Operating time: 8 hours per day
S Installation: According to instructions in manual.
If
the maintenance period
is extended, it is recommended that the ambient temperature be lowered
and that the power-on time be reduced as much as possible.
Note For details regarding maintenance, consult your OMRON sales representative.
