1. Press the OFF button more than 3
seconds.
CAUTION: The load is no longer protected by the
UPS. It is powered via the Bypass AC
source. If the UPS is set in frequency
converter mode, the load will not be
powered.
If the Bypass AC source is out of
tolerance, the UPS will generate a
calibrated 10msec output interrupt.
2. Set the battery circuit breaker(s) to the
OFF position.
3. Set the Normal AC source circuit breaker
to the OFF position.
LED is now OFF.
CAUTION: Performing this step will disconnect
power to the load.
4. For the complete shutdown of the UPS (no
input and output power), the upstream circuit
breaker (not included) should be set to the
OFF position.
