5.5 Protective ground connectionIn accordance with the defined networks in DIN EN 60990, the frequency inverter has a leakagecurrent > 3.5 mA and must therefore be permanently connected. In accordance with EN 50178, item5.2.11 and 5.3.2.1, the PE conductor connection must have a cross-section of at least 10 mm². In thecase of PE conductors < 10 mm², an additional PE conductor must be connected. The cross-sectionmust correspond at least to the cross-section of the PE conductor on the connecting lead. M6threaded bolts are available on the ZETADYN 4 for connecting the PE conductors (see fig.).Protective earth conductor connection ZETADYN 4C5.6 Mains connection (X1)Danger!Before connecting to mains you have to check if the technical Datas on the rating plate of theZETADYN 4 are according to the required connecting values.5.6.1 Network formThe mains filter and ZETADYN 4 are designed for use in an earthed supply system. Permissiblenetwork forms are:• TN network• TT networkInformationThe line filter and ZETADYN 4 are unsuitable for use in the IT network!5.6.2 Cable cross sectionThe line cross-section must be specified dependent on the motor’s rated current and the ambientconditions (e.g. temperature, wiring method) in accordance with DIN VDE 0100.5.6.3 Mains fuseThe fuseprotection is implemented in accordance with the line cross-section used5.6.4 Type of cableBoth rigid and flexible lines can be utilized. The use of wire-end sleeves is recommended for flexiblelines.The mains line does not have to be shielded.5.6.5 ConnectionThe mains connection is designed with spring contact terminals. To avoid damage to the connectionterminals and to ensure a safe contact, a suitable screwdriver must be inserted into the terminals asfar as it will go to fully open them when connecting cables.Translation of the original operating instructionsZETADYN 4C Electrical installationR-TBA12_01-GB 1415 Part.-No. 00163371-GB23/2045 Electrical instal-lation
