2. Torque each of the fasteners to 4 Nm or 35 in - lbs.
3.
Make sure the DC connections to be installed are not powered by turning off circuit breakers assigned to this frame
and checking with an Ohm meter.
4. Open the distribution panel door on the right end of the shelf.
5. Run 4 DC branch circuits back to the - 48V source - Each feed supplies half of the shelf. A&B feeds for side 1 and
A&B feeds for side 2.
each circuit to support 42 Amp List 2 Drains. Note: Lug landings are ¼ inch studs on 5/8 inch centers. Use a
minimum of 6 AWG conductor for environments up to +65°C (reference for applications of not
more than three conductors in a raceway and correction factors for Ambient Temperatures Over 30°C). Each instal-
lation will vary and the installer should review NEC cabling requirements as well as local practice to ensure proper
cable sizing is achieved for the local conditions.
Lugs for 6AWG conductor are as follows or available equivalent:
Burndy YAV6C - L2TC14 - FX
6. Using the hardware supplied, attach the return wires for all 4 circuits.
