This task covers:
a.
Removal
b.
Test
C.
Installation
General Mechanic’s Tool Kit
(item 2, appendix B)
Automotive Fuel and Electrical System Repair,
Tool Bit (item 3, appendix B)
Reference
Shut down Generator Set
150 kW, paragraph 2.8.1.
Thermoconductive paste (item 8, appendix E)
Two
WARNING
The Generator Sets 150 kW produce lethal voltages.
Turn off power to the EPP III or Generator Set 150 kW before
performing any installation, removal, disassembly, or
assembly work.
Wear protective gloves when performing any work on main
assemblies of the EPP III.
CAUTION
Label all cables before removing electrical or electronic assemblies or
components.
NOTE
This procedure is the same for diodes V1 and V2.
a. Remove stanchion by PDU (1, figure 5-12).
b.
Open access door (2) and secure with prop (3).
c. Install stanchion.
d. Record labeling and position of cables on heat sink (7).
e.
Remove screws (4, 6) and integrated washers, and cables.
f.
Unscrew diode (5) from heat sink (7).
Use multimeter to check continuity resistance between connections of diode (5). Resistance must be
infinity in the reverse direction of the diode, and less than 0.3 Ohm in the forward direction.
a. Install diode (5) into heat sink (7), first coating contact surface with thermoconductive paste.
b. Install cables on heat sink (7) with screws (4, 6) and integrated washers.
