Optima 320 Series
3 Operation
3.1 Startup
Switch the breaker(s) on the PDU chassis to the off position.
Insert the PDU’s inlet connector into the facility mains power source. If there is a facility power disconnect, switch that to
the On position. At this point, the PDU is energized, though the indicator lamps will be off.
Switch the PDU’s breaker(s) to the On position, and the indicator(s) will be lit. All outlets are now powered.
3.2 Breakers
Various models have one breaker or two circuit breakers. The 320001 does not have a circuit breaker.
When there is a single breaker, in effect this behaves like a main breaker, protecting the whole unit, and providing on/off
control for the whole unit.
When there are two breakers, each breaker protects one group of outlets. Outlets are organized into identical groups. The
breaker on the front panel protects the outlets on the front panel, and the breaker on the back panel protects the outlets
on the back panel. (The back panel is the one with the inlet connection.)
Each breaker has it’s own indicator. When lit, power is being supplied to the correlating outlet group.
3.3 Digital Meter
Some models include the monitoring and digital display of volts and amps. The meter will auto rotate every 5 seconds
between the volts and amps values. Volts are shown as whole numbers. Amps are shown with one decimal place. Both
values are ≤ ± 2%, and are recalculated every 15 seconds.
