Optima 529 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 three breakers.
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 three breakers, each breaker protects one group of outlets. Outlets are organized into identical groups.
Following the length of the PDU from the inlet, the first breaker operates the first group of outlets, etc.
Each breaker has it’s own indicator. When lit, power is being supplied to the correlating outlet group.
All models use 2-pole breakers with both line and neutral routed through the breaker.
