A dual pole breaker is needed for the installation. For NCS 5501 and 5501-SE, the rating of the dual pole
breaker is 40A with wire size of 10 AWG. For Cisco NCS 55A1-36H-S, NCS 5502 and 5502-SE, the
rating of the dual pole breaker is 80A with wire size of 6 AWG.
Note
Step 1
Verify that the correct fuse panel is installed in the top mounting space.
For a 40-72 VDC power supply for maximum 1100 W power, the fuse rating must be 80 A. There is an option for 240-380
VDC power supply for maximum 1100 W power, the fuse rating must not exceed 40 A.
Step 2
Measure and cut the cables as needed to reach the chassis from the fuse panel.
Step 3
Dress the power according to local practice.
Step 4
Connect the office battery and return cables according to the fuse panel engineering specifications.
Step 5
Insert the DC connector into the DC receptacle on the power supply.
