The 1336-SN-SP1C Inverter and Converter Snubber Board Kit is a replacement part for the Allen-Bradley 1336 Force, Plus II, Plus, and Impact drives. It is a stand-alone inverter and converter board replacement kit that contains 1 converter snubber board and 1 inverter snubber board. Generally, all snubber boards help to suppress any rise in voltage transients in the drive’s circuit. The 1336-SN-SP1C Inverter and Converter Snubber Board Kit is installed on both sides of the converter and inverter assembly of the 1336 drive. The 1336-SN-SP1C Inverter and Converter Snubber Board Kit is backward-compatible and it can be used as a replacement for the Allen-Bradley 1336-SN-SP1A and 1336-SN-SP1B snubber boards. They are built for the 1336 Plus, Plus II, Impact, and Force digital drives with 460 Volts AC operating voltage. The 1336-SN-SP1C Inverter and Converter Snubber Board Kit is compatible with the C-Frame drives in the 1336 Plus, Plus II, Impact, and Force digital drives of all ratings except the 40.0 to 60.0 Horsepower rated drives. The 1336-SN-SP1C Board Kit, like every 1336 drive part, is designed to be field-installable.

To install the 1336-SN-SP1C Inverter and Converter Snubber Board Kit, turn off the power from the drive, and check it for zero voltage. Loosen the screws fastening the old snubber board to the bus bars, and remove the old board. Attach the new board (the 1336-SN-SP1C Inverter and Converter Snubber Board Kit) to the bracket and fasten it with the 7 factory-supplied screws with an 18.0 pounds on an inch of torque (specified rating). The 1336-SN-SP1C Inverter and Converter Snubber Board Kit has environmental ratings similar to all other 1336 drives and parts and they can function optimally with or without an enclosure.
