3 Maintenance
3.1 System Maintenance Procedures
It is recommended to perform the maintenance procedures listed in Table 3.1 every 6 months to ensure continual system operation.
Table 3.1 Maintenance Procedures to be Performed at 6-Month Intervals
Check ventilation openings for obstructions such as dust, papers, manuals, etc.
Inspect and tighten all installer's connections.
3.2 Adding a Module to an Existing Module Mounting Shelf
3.2.1 General
To increase system current capacity, a rectifier module can easily be added to an existing module mounting shelf that contains an
empty rectifier module mounting position. Likewise, to increase subsystem capacity, a -48 VDC to +24 VDC DC-DC converter module
can be added to a module mounting shelf that contains an -48 VDC to +24 VDC empty converter module mounting position. Also a
-48 VDC to -58 VDC DC-DC converter module can be added to a module mounting shelf that contains an empty -48 VDC to -58 VDC
converter module mounting position.
Rectifier and converter modules can be inserted or removed with power applied (hot swappable).
3.2.2 System with List 7 Distribution Cabinet
In the top module mounting shelf, rectifier modules can be installed in any mounting position except the far left. Converter modules
(-48 VDC to +24 VDC) CANNOT be installed in the top shelf. See Figure 3.3.
In the bottom module mounting shelf, rectifier modules can be installed in any mounting position. Converter modules (-48 VDC to
+24 VDC) can be installed in any of the three far right mounting positions (as viewed from the front). See Figure 3.3.
3.2.3 System with List 27 Distribution Cabinet
Rectifier modules can be installed in any mounting position of each module mounting shelf. Converter modules can be installed in any
of the three far right mounting positions of each module mounting shelf (as viewed from the front). See Figure 3.4. See Alerts below
for restrictions.
3.2.4 Adding a Module to an Existing Module Mounting Shelf
NOTE!
Each rectifier and converter module locks into the module mounting shelf by means of a latch located on the bottom
of the module. The latch and module handle are interactive. Pushing the handle up into the module's front panel causes the
latch to extend to the locking position; pulling the handle down out from the module's front panel causes the latch to retract.
See Figure 3.3 or Figure 3.4.
WARNING! To prevent damage to the latching mechanism, ensure the handle is in the open position when installing or
removing a module. NEVER hold the handle in the closed position when installing a module into a shelf.
