Maintenance

All work may only be done by qualified personnel. The security must be ensured as follows:
• Disconnect power supply at MCCB
• Secure against restarting
• Await discharge time of capacitors (if necessary controlling by measurement at „+PA" and „-", respectively
"++" and „--")
• Ensure loss of voltage by measurement
In order to avoid premature ageing and avoidable malfunctions, the measures mentioned below must be carried
out in the appropriate cycle.

Function
Pay attention to unusual noises of the motor (e.g. vibrations) as well as of the frequency inverter
(e.g. fan).
Pay attention to unusual smells of the motor or frequency inverter (e.g. evaporation of capacitor
electrolyte, braise of the motor winding)
Check unit for loose screws and plugs and if necessary tighten up.
Clean frequency inverter from dirt and dust deposits. Pay attention especially to cooling fins and
protective grid of the fans.
Examine and clean extracted air filter and cooling air filter of the control cabinet.
Examine function of the fans of the KEB COMBIVERT. The fans must be replaced in case of
audible vibrations or squeak.
Make a visual leak test of the cooling circuit for water-cooled inverters.
