The disconnecting device must be of a type thatcan be locked to the open position for installation and maintenance work.<strong>ACS800</strong>-02 and <strong>ACS800</strong>-U2 with enclosure extension, <strong>ACS800</strong>-07 and <strong>ACS800</strong>-U7These units are equipped with a hand-operated input disconnecting device(disconnecting means) which isolates the drive and the motor from the AC power asstandard. The disconnecting device does not, however, isolate the input busbarsfrom the AC power. Therefore, during installation and maintenance work on thedrive, the input cables and busbars must be isolated from the input power with adisconnector at the distribution board or at the supplying transformer.EUTo meet the European Union Directives, according to standard <strong>EN</strong> 60204-1, Safetyof Machinery, the disconnecting device must be one of the following types:• switch-disconnector of utilization category AC-23B (<strong>EN</strong> 60947-3)• 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 (<strong>EN</strong> 60947-3)• circuit breaker suitable for isolation in accordance with <strong>EN</strong> 60947-2.USThe disconnecting means must conform to the applicable safety regulations.FusesSee section Thermal overload and short-circuit protection.Planning the electrical installation
