To satisfy LVD (Low-voltage Directive) requirements, the system must be
protected by a molded case circuit breaker (MCCB) when a short-circuit
occurs. A single MCCB may be shared with more than one Inverter or with
other machines. In that case, however, take some appropriate measures so
that the MCCB will protect all the Inverters from the occurrence of any single
short-circuit.
The frequency reference power supply (FS) of the Inverter is of basic
insulation construction. When connecting the Inverter to peripheral devices,
be sure to increase the degree of insulation.
