10.0 UNPACKING AND INSPECTION
10.1
This 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.
10.2
If there is evidence of damage, do not attempt to test the unit. The freight carrier should
be notified immediately and a claim for the cost of the rectifier system should be filed with
the carrier for direct reimbursement. Be sure to include the model and serial number of the
damaged unit in all correspondence with the freight carrier. Also save the shipping carton
and packing material as evidence of damage for the freight carrier’s inspection.
10.3
UNIPOWER will cooperate fully in case of any shipping damage investigation.
10.4
Always save the packing materials for later use in shipping the unit. Never ship the rectifier
system without proper packing.
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 bracket offsets are every quarter inch from front to back.
11.2 Connections.
Input connections should be made with one- or two-terminal crimp type lugs
using copper wire size from no. 1 to 8 AWG, depending on current and wire loop distance.
See Sections 9.2 and 9.3. Output connections are made to the barrier terminal strips. See
Section 9.4 and Figure 7.
NOTE: Single feed models with option S fitted have both left and right side input bus
bars fitted. It is only necessary to connect the input feed to one side for correct operation.
The unused side is directly connected to the live input feed and can be used for supplying
additional panels. See figure 8 below.
CAUTION:
The total load must not exceed 80A for DPGF1U or 150A for DPBF1U on any
one pair of bus bars in the chain.
