Replacing the Snubber Board(s)

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.

What This Kit Contains

This kit contains a replacement converter diode and these instructions. This kit does Not

contain the thermal compound Required to mount a new diode.

Locating the Converter Diodes

The converter diodes are located on the Multipulse bridge heatsink assembly in the converter bay of your drive. A typical heatsink assembly is shown in the following illustration. Converter diode locations may vary on some models.

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.
