10.0 UNPACKING AND INSPECTION 10.1 This DCPDU2B Series power distribution panel was carefully tested, inspected and packaged for shipment from our factory. The unit and circuit breakers are shipped separately. Upon receipt of the unit it should be carefully unpacked and inspected for any damage in shipment.
Installation Manual | DCPDU2B Series Power Distribution Units 11.0 INSTALLATION 11.1 Mounting. This distribution panel can be mounted in either 19- or 23-inch racks by using the supplied reversible brackets. Mount it from the front of the rack using the correct offsets to align with existing rack-mounted equipment.

The above table is based on the following: 1) Use of Carling (C Series) breakers or CBI (D Frame) breakers. Breakers in these series are equivalent in fit, form, and function and can be used interchangeably within the same system. 2) The DCPDU2B panel is rated for continuous operation at a maximum input of 450A per side @ 35C max., 400A per side @ 40C max., 320A per side @ 50C max., and 200A per side @ 70C max.
Installation Manual | DCPDU2B Series Power Distribution Units 13.0 SETUP AND TESTING 13.1 It is not necessary to have the distribution panel mounted in a rack for initial testing. This can be done on a bench. It is also not necessary to have loads connected to the panel for this testing.
