1. This AVR may be installed in any suit-
able location on the generator set. The ap-
pearance and mounting holes are shown in
Figure 1.
2. To ensure safety and avoid permanent
damage to the AVR caused by high voltage,
be sure to remove the wiring on the AVR be-
fore using meg-ohm meter / high voltage
test equipment.
3. Be sure to tie up the connection wiring of the
AVR when installing in a high-vibration
environment. The heat sink may become
hot and could damage the wiring.
