energized during maintenance bypass operation. In order to deenergize all UPS parts, circuit
breakers on mains and bypass mains distribution panels feeding the UPS and circuit breakers
on external battery cabinet shall be brought to “OFF/0” position. Internal batteries shall also
be isolated from the system.
