Planning the electrical installation38Supply connectionUse a fixed connection to the AC power line.WARNING! As the leakage current of the device typically exceeds 3.5 mA, a fixedinstallation is required according to IEC 61800-5-1.Supply disconnecting deviceInstall a hand-operated input disconnecting device (disconnecting means) betweenthe AC power source and the drive. The disconnecting device must be of a type thatcan be locked to the open position for installation and maintenance work.EuropeIf the drive is used in an application which must meet the European Union MachineryDirective according to standard EN 60204-1 Safety of Machinery, the disconnectingdevice must be one of the following types:ï a switch-disconnector of utilization category AC-23B (EN 60947-3)ï a disconnector that has an auxiliary contact that in all cases causes switchingdevices to break the load circuit before the opening of the main contacts of thedisconnector (EN 60947-3)ï a circuit breaker suitable for isolation in accordance with EN 60947-2.Other regionsThe disconnecting means must conform to the applicable safety regulations.Thermal overload and short circuit protectionThermal overload protectionThe drive protects itself and the input and motor cables against thermal overloadwhen the cables are dimensioned according to the nominal current of the drive. Noadditional thermal protection devices are needed.WARNING! If the drive is connected to multiple motors, a separate thermal overloadswitch or a circuit breaker must be used for protecting each cable and motor. Thesedevices may require a separate fuse to cut off the short-circuit current.Protection against short-circuit in motor cableThe drive protects the motor cable and the motor in a short-circuit situation when themotor cable is dimensioned according to the nominal current of the drive. Noadditional protection devices are needed.
