Converter Assembly Component Replacement Procedures
Install Components
1. Use isopropyl alcohol to clean the surface where the new Snubber
Resistor(s) will be installed.
2. Verify that the mounting surface of the new Snubber Resistor(s) is clean. If
not, clean with isopropyl alcohol.
3. Use a 3-inch paint roller or putty knife to apply a thin even coating of the
supplied thermal grease to the mounting surface of the new Snubber
Resistor(s) and install.
4. Install the new Snubber Resistor(s). Torque the mounting screws to
2.9 N•m (26 lb•in).
5. Reconnect all wires for the Snubber Resistor(s).
6. Reassemble remaining components in reverse order.
7. Replace all safety shields and enclosure covers before applying power to the
drive.
