20. When each gate-driver circuit has been checked, disconnect the power
supply and remove it from the cabinet. Disconnect the current loop cable
from the terminal blocks and lay it on the cart.
21. Open the switch SW2 on the interface board ( Figure 27 ) before returning
the unit to service. Ensure the red LED is off.
22. Remove the fibre optic cables from the fibre optic board and gently coil the
cable bundle on the SCR Power truck to be racked in.
23. Replace the clear polycarbonate barriers on the SCR Power Truck and
secure with two screws at the top and two screw at the bottom on both the
front and the rear.
24. Carefully rack in the SCR Power Truck, connect all the fibre optic cables
on the fibre optic board, and the temperature fibre optic cable to the
bulkhead connector. Connect the current loop cables in the terminal
blocks routing the cable through the ties provided.
25. Finally make the Power connections with the flexible links to the Bus and
torque to 20 lb•ft (27 N•m). Take care not to drop any hardware during
the process of re-connecting the links.
ATTENTION: The clear barriers provide insulation between the converter
module and the enclosure and unit Bus at the rear . They must be replaced
before re-installing the converter modules. Failure to do so may result in arc
faults which could result in burns, injury or death.
