Note 7) Products other than Option R are not equipped with an earth leakage breaker. Purchase an appropriate earth leakage breaker separately. Note 8) If the product is subjected to a short power outage (including voltage sag), it may take a long time to resume normal operation or be unable to restart normally due to the protective equipment triggered after the power is recovered.
