Replacing the Converter Diode(s)
To replace the converter diode(s), follow these steps:
ATTENTION: Disconnect and lock out power from the system
before disassembling the bridge. Failure to disconnect power
may result in death or serious injury. Verify bus voltage by
measuring the voltage between +DC and –DC on terminal block
TB1 located at the bottom of the 1336 Drive in the Inverter Bay.
Do not attempt to service the drive until the bus voltage has
discharged to zero volts.
1. Remove the power leads to + and -bus bars at the connection points at
the top of the bus bars.
2. Remove the + / - bus bars that are over the converter diode by removing
all the screws at the “A” and “K” mounting points on each diode.
Fan
3. Remove the “AK” input terminal from the converter diode you will be
replacing. Tag leads if you are replacing more than one diode.
4. Remove the mounting screws from the converter diode. The diode will
have two or four mounting screws depending on the model. For
example: the DD104N shown in the accompanying illustration has two
mounting screws, while the DD350N has four.
5. Remove the converter diode.
A. Remove all old heat transfer compound from the heatsink mounting
surface using a tool such as a rubber spatula that will not mar the
heatsink surface. Remove any remaining residue with a soft cloth and
a cleaning fluid such as Essex Cleaning Fluid (Brownell OS-3) by
Dow Corning Co.
B. Use a non-marring cleaning pad such as a Scotchbrite by 3M™ to
remove any oxidation from the heatsink mounting surface and the
face of the diode. DO NOT use steel wool or sandpaper!
C. Follow oxidation removal with a final cleaning with cleaning fluid.

Important: Thermal Compound must be applied immediately to both
surfaces to prevent oxidation from reoccurring.
6. Apply a thin, even coat of Thermal Compound (not supplied) to the new
diode and the mounting surface. Dow Corning 340 is the recommended
Thermal Compound.
7. Position the new converter diode being careful to match the holes for
the screws.
8. Tighten the screws (2 or 4 depending on model) in the sequence shown
in the illustration, to the Mounting Screw torques in Table 3.

Bay of the cabinet. Do not attempt to service the drive until the
bus voltage has discharged to zero volts.
Important: If your thermal switch is NOT located under a bus bar, it will
not be necessary to perform steps 1, 2, 7 or 9.
1. Remove the flex bus or wire connected to the “AK” input terminal bus
bar or diode that is located over the thermal switch you need to replace.
2. If your unit is equipped with a bus bar, remove it.
3. Remove the red power wires from the thermal switch.
4. Remove the thermal switch.
5. Thread in the new thermal switch by hand until it is snug.

Spare Parts
To determine spare parts for your Bridge Assembly, follow these steps:
A. Determine Drive Size (HP) using Table 6 for CT or Table 7 for VT and
then the type of multi-pulse transformer used in the drive package.
B. Find drive size and move to the right until you are under the column
which describes the transformer. That number is the bridge assembly
number (Table 8).
