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.
