3.8.5 Finalize DR Filter Box and HPA Installation
Open or loose RF connections during operation may cause electric arcs
that can cause burns and eye injuries, as well as damage equipment.
Always ensure that all HPA compartment frame backplane components
are tightened once the DR filter box and HPA’s are installed.
Once the installation of the DR filter box and HPA’s is complete, the components which are
mounted to the HPA compartment frame backplane must be secured in place. A torque
rating of 10.8 Inch Lbs. must be used to tighten the 8-32 socket head cap screws which
secure these components to the HPA compartment frame backplane.
3.8.6 HPA PSU 30 VDC Rectifier Module
The HPA PSU mounting shelf includes two (2) empty slots for the HPA PSU 30 VDC rectifier
modules. Please refer to Figure 3-13
, Figure 3-14 or drawing SX03-10000-03-D01 for the
mounting position of the rectifier modules.
The HPA PSU 30 VDC rectifier modules should be installed in the following sequence:
1. Slide the black release button on the rectifier module front grill/cover cover to the
right to release the grill/cover from the front of the rectifier module.
2. Position the rectifier module so that the open grill cover is facing down.
3. Slide the rectifier module into either of the empty slots on the HPA PSU mounting shelf
until it stops – see Figure 3-23
.
4. To secure the rectifier module in place, lift the grill cover up and push it towards the
rectifier module until it clicks in place. As the grill cover is pushed in place, the
rectifier module will slide all the way into the slot.
5. Repeat steps 1 through 4 for the second rectifier module.
