H Conformance to LVD
Be sure to insert a molded-case circuit breaker (MCCB) into the power line connected to the Inverter for
short-circuit protection. A single MCCB is required by each Inverter.
The frequency reference power supply (FS) is basic isolation. Its insulation needs to be reinforced when
connecting to a peripheral device.
