7 Servicing/Maintenance

7.1 Safety regulations

The operator ensures that maintenance, inspection and installation is performed by
authorised, qualified specialist personnel who are thoroughly familiar with the
manual.

WARNING

Unintentional starting of the drive or driven machine

Risk of injury by moving components and shock currents!

▷

Always make sure the electrical connections are disconnected before carrying
out work on the drive or driven machine. In addition to the main circuits,
ensure that supplementary and auxiliary circuits are also disconnected.

▷

Mind the capacitor discharge time. After switching off the frequency inverter,
wait 10 minutes until dangerous voltages have discharged.

▷

Ensure that the drive cannot be started unintentionally.

WARNING

Insufficient stability

Risk of crushing hands and feet!

▷

Secure the motor against tilting or tipping over during assembly/dismantling.

A regular maintenance schedule will help avoid expensive repairs and contribute to
trouble-free, reliable operation of the drive with a minimum of maintenance
expenditure and work.

NOTE

All maintenance work, service work and installation work can be carried out by KSB
Service or authorised workshops. For contact details please refer to the enclosed
"Addresses" booklet or visit "

www.ksb.com/contact

" on the Internet.

Never use force when dismantling and reassembling the drive.
