7.1.1 Routine Inspection Items
Inuence of ambient temperature, humidity, dust and vibration will cause aging of components in the AC drive,
which may cause potential faults or reduce the product life. Therefore, it is necessary to carry out routine and
periodic maintenance. More frequent inspection will be required if it is used in harsh environments, such as:
High ambient temperature;
Frequent starting and stopping;
Fluctuations in the AC power supply or load;
Excessive vibrations or shock loading;
Dust, metal dust, salt, sulfuric acid, chlorine atmospheres;
Poor storage conditions.
Check the following items routine to avoid deterioration in performance or product. Copy this checklist and sign
