* 1. Use a ground fault interrupter with high-frequency countermeasures (for Inverters) and a sensitivity amperage of 30 mA or higher for each Inverter. If a ground

fault interrupter without such countermeasures malfunctions, lower the carrier frequency of the Inverter or use a ground fault interrupter that provides appropriate

countermeasures. Alternatively, use a ground fault interrupter with a sensitivity amperage of 200 mA or higher for each Inverter and an operating time of 0.1 s.

Example: NV Series by Mitsubishi Electric Corporation (manufactured in or after 1988)

EG or SG Series by Fuji Electric Co., Ltd. (manufactured in or after 1984)

* 2. When using the auto restart function, note that the Inverter is set to trigger a fault output whenever the fault restart function is activated (L5-02 = 1), then a

sequence to interrupt power when a fault occurs will result in shutting off the power to the Inverter as the Inverter attempts to restart itself. The factory setting for

L5-02 is 0 (fault output not active during restart attempt).

* 3. The finemet zero-phase reactor is manufactured by Hitachi Metals.

* 4. To use the Separate Power Supply Unit, a dedicated Inverter Unit to handle the separate power supply is required. Contact your Yaskawa representative for

details.
