Step 1. Before installing the HDN, attach the four connecting bus bars supplied with the PTP to the power inputs of the HDN
using the provided 3/8"x1" bolts, at washers and lock washers. The two HOT bus bars (the larger two of the four bus bars)
require four bolts each. The two RETURN bars (the smaller bus bars) each require two bolts. Recommended Grade 5
Torque Value: 350 in·lbs
WARNING
USE ONLY THE PROVIDED 3/8"16 X 1" BOLTS, SPLIT WASHERS, AND FLAT WASHERS. USE OF OTHER HARDWARE MAY DAMAGE
THE PANEL.
Step 2. Install the HDN in the rack rst, but do not connect any cables to it. When installing the HDN, be sure to leave at least
2RU of free rack space above the panel for the PTP.
Step 3. Orient the PTP rack mount ears appropriately for a 19 or 23 inch rack. Install the rack mount ears using the included
Phillips Head screws through the two holes near the front of the panel.
Step 4. Install the PTP in the rack. Be sure the four input bus bars attached to the back of the HDN are aligned with the bus bars
of the PTP.
Step 5. Secure the connecting bus bars on the HDN to the PTP using the 3/8-16x1" bolts provided. Each connecting bus bar
requires two bolts. In the two hole positions, the bolt also retains the mounting bracket for the rear cover. See "Figure
17. PTP Power Termination Panel connected to the HDN bus bars" on page 16. Recommended Grade 5 Torque Value:
350 in·lbs
Step 6. Install a piece of clear heatshrink tubing over each of the power cables prior to connecting the cable lugs to the PTP bus
bars.
Step 7. Install the incoming DC feeder cables for the A and B power inputs and A and B returns. The cables can feed in from the
rear of the PTP or feed down from the top. The bus bars of the PTP support lugs with 1" hole spacing.
Step 8. Secure the cable lugs to the bus bars using the provided 3/8" x 1 1/4" and 3/8" x 1 1/2" bolts, at washers and lock
washers. Recommended Grade 5 Torque Value: 350 in·lbs
Step 9. Knock out the sections of the plastic cover that match your input feeder landings (either rear-entry or top-entry), then
install the plastic cover using the 1/4-20 serrated head screws provided. See "Figure 18. Secure the plastic safety shield to
the PTP Power Termination Panel" on page 16.
