Replacement Procedures
Solar Converter Module Replacement
Solar converter modules can be inserted or removed with power applied (hot swappable).
NOTE!
Each solar converter module locks into a module mounting shelf by means of a latch located on
the bottom of the module. The latch and solar converter 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 7
.
DANGER! Take care when removing a solar converter module that was in operation, as solar converter
module surfaces could be very hot.
WARNING!
To prevent damage to the latching mechanism, ensure the handle is in the open position
when installing or removing a solar converter module. NEVER hold the handle in the closed position
when installing a solar converter module into a shelf.
Procedure
NOTE!
Refer to Figure 7 as this procedure is performed.
1. Performing this procedure may activate external alarms. Do one of the following. If possible, disable
these alarms. If these alarms cannot be easily disabled, notify the appropriate personnel to disregard
any alarms associated with this system while this procedure is performed.
2. Loosen the captive screw on the module’s handle. Pull the handle down out from the module’s front
panel (this will also retract the latch mechanism). See
Figure 7
.
3. Grasp the handle and pull firmly to remove the module from the shelf.
4. Place the replacement solar converter module into the mounting position without sliding it in
completely.
5. Loosen the captive screw on the module’s handle. Pull the handle down out from the module’s front
panel (this will also retract the latch mechanism). See
Figure 7 .
6. Push the module completely into the shelf.
7. Push the handle up into the module’s front panel. This will lock the module securely to the shelf.
Tighten the captive screw on the handle.
8. Certain functions (i.e. solar converter addressing) may require adjustment when adding or replacing a
solar converter module. Refer to the Power System documentation for instructions.
9. After the solar converter modules are physically installed in the mounting shelf(s), they are ready for
operation immediately after power is supplied to them. Verify that the solar converters are operating
normally.
10. Enable the external alarms, or notify appropriate personnel that this procedure is finished.
11. Ensure that there are no local or remote alarms active on the system.
