Panduit PN380C TEST AND TURN-ON

DPOE™ Power System User Manual Part Number: PN380C

TEST AND TURN-ON

Once all AC and DC connections have been secured and checked, install each rectifier sequentially by

sliding and latching it into the chassis as illustrated in the section below.

The rectifiers for use in the DPOE™ Power System are equipped with Light Emitting Diodes (LEDs) on

the front panel as a means to indicate problems with that specific rectifier. The rectifiers are designed as

modular, field replaceable units.

Plus all AC power cords into an appropriate Power Supply Unit (PSU), or Uninterruptible Power Supply

(UPS).

In the event that a rectifier needs to be removed, press the latch button on the front of the rectifier to

release the latch handle. Pull the latch handle until the rectifier clears the rear connector on the chassis,

then gently slide it out of the rear connector. With the latch handle open on the replacement rectifier, slide

the rectifier in until it connects with the backplane. While pressing the latch button down, use the latch

handle to gently ease the rectifier into the rear connector. When the rectifier is properly seated, releasing

the latch button will hold the latch handle in place.

WARNING: The latch handle must be open for installation or removal of a rectifier. Attempting

to install a rectifier with the latch handle closed will result in mechanical damage to

the rectifier and the DPOE™ Power System chassis.

The rectifier will power up and configure itself. It will start in high fan speed mode and reduce the speed

according to the ambient and plant conditions within 10 seconds.

ILimit can be adjusted up to +105% of the rated current of the rectifier. The system voltage will remain

constant up to ILimit at which point the system voltage will drop quickly toward 0 VDC. Once a 48V rectifier

output drops below 12 VDC for more than 5 seconds, the system will shut down. The system will

automatically restart after 60 seconds, and will continue until the short circuit is cleared.
