Disconnection from the mains If the device must be dismantled, e.g. for service purposes, it can be isolated from the mains without having to remove the wiring at the electrical connection.

  • Page 91: Disconnection From The Mains With Kp/Kph And Kes Electrical Connection

    Loosen the screws [2]. Remove electrical connection. Cover [1] and plug-in type frame [4] or connection frame [5] remain together. Seal open plug/socket connection, e.g. using AUMA protection cover and parking frame. Clean sealing faces of plug/socket connector and housing.

  • Page 92: Maintenance

    Electrical connection cables must be placed properly and in perfect condition. Thoroughly touch up any possible damage to painting to prevent corrosion. Original paint in small quantities can be supplied by AUMA. Cable entries, cable glands, plugs etc. have to be checked for correct tightness and sealing.
