Regular Maintenance
Check the items below during regular maintenance.
Before starting inspection, always turn the power off, then wait at least one minute after
all indicators on the front panel go off. Touching terminals immediately after turning the
power off may cause an electrical shock.
•
Check the terminal block screws for looseness.
•
Check if electrically conductive dust or oil mist adheres to the terminal block.
•
Check the Inverter set screws for looseness.
•
Check if dust or dirt builds up on the heat sink (aluminum portion on the rear of the
Unit).
•
Check if dust builds up in the air vents.
•
Check if the appearance is normal.
•
Check if the cooling fan for the control panel operates normally. (Check for noise or
abnormal vibration, and also check if the total hours of operation has exceeded the
value shown in the specifications.)

Regular Parts Maintenance
An Inverter consists of many different parts. It can provide its full performance only when
these parts operate normally. Some electronic parts require maintenance depending on
the service conditions. To allow the Inverter to operate normally over an extended peri-
od of time, always perform regular inspection and parts replacement according to the
service life of each part.
Regular inspection intervals vary according to the Inverter installation environment and
service conditions.
The maintenance interval for this Inverter is shown below. Use this information as a
guide to regular maintenance.
The standard interval for regular maintenance is as follows:
Electrolytic capacitor: Approximately 5 years (8 hours of operation per day)
As for service conditions, it is assumed that the ambient temperature of the Inverter
is 40
°
C, and the Inverter is used under rated operating conditions (rated torque) and
is installed as specified in the User’s Manual.
To extend maintenance intervals, ambient temperatures should be lowered, and power-
on time should be minimized.
Note For the maintenance method, contact your nearest local sales representative.
