Replacement Procedures
Fuse Replacement
The motor drive circuit contains two fuses. They are located on the power distribution PWA. If it becomes
necessary to replace these fuses, follow the procedure in
Table 36 and refer to Figure 36 for fuse location.
Disconnect power before opening the actuator case to replace the fuse(s). A
potentially lethal shock hazard exists inside the case if the unit is opened while
powered.
