17. To release the LCL filter module, remove the two remaining M10 x 20 mm
screws.
18. Remove the power modules from the enclosure.
Install the Power Module in the Enclosure
Install the power module into the enclosure in the reverse order of removal.
When installing the fiber-optic cables:
1. Remove the transceiver from the fiber-optic port on the power layer
interface circuit board.
2. Without bending the cable to a radius less than 50 mm (2 in.), fully insert
the fiber-optic cable into the transceiver.
3. Insert the transceiver and fiber-optic cable into the port on the board, until
you hear an audible ‘click.’
DC Link Fuses Replacement
Replace the DC link fuses with the appropriate kit catalog number that is
identified in Tab le 21
.
IMPORTANT
Minimum inside bend radius for fiber-optic cable is 50 mm
(2 in.). Any bends with a shorter inside radius can
permanently damage the fiber-optic cable. Signal
attenuation increases as inside bend radius is decreased.
IMPORTANT It is recommended that you replace both DC link fuses for each power module
installed.
