IMPORTANT INFORMATION FOR SELECTING REPLACEMENT INVERTERS!!!

Inverters on F8W and F8J machines are both GPD333. However, the eprom used in each inverter is unique for each machine. If a machine is down because of a bad invertor, it is possible that an inverter you may have in stock is not the proper one for that particular machine. Several cases have been noted where the wrong inverter was given as replacement.
Although no difference can be noted simply by looking at the inverters, they do have different MILNOR part numbers. The F8W uses inverter part number 09MV050E74. The F8J uses inverter part number 09MV050D74. To distinguish the inverters without a part number: constant #49 will display the eprom version. F8W eprom versions are 8002 and 8001. F8J eprom versions are 8111 and 8112.
