Recommended annual cleanings by user
• Clean the IP22 (Ul Type 1) and IP42 (UL Type 1 Filtered) inlet meshes on the cabinet door.
• Clean the interior of the cabinet and drive module heatsinks.
Recommended annual inspections by user
• Examine the tightness of the cable and busbar terminals. Tighten if needed.
• Make sure that the operation conditions (dustiness, moisture, temperature) agree with the drive specifications.
(I) Visual inspection and maintenance action if needed
P Performance of on/off-site work (commissioning, tests, measurements or other work)
R Replacement of component if ambient temperature is below 40 °C (104 °F) and there is no cyclic heavy load and no
continuous nominal load.
(R) Replacement of component in demanding operation conditions: ambient temperature is constantly higher than 40 °C
(104 °F) or ambient conditions are especially dusty or humid or if the load is cyclic or if normal load is constantly high.
