personal injury.
Disconnect power before working
on this equipment.
In rare circumstances, such as when changing a circuit breaker
or a fusible switch or when a unit is taken apart, it may be
necessary to adjust the disconnect operating handle. (The
Siemens fusible disconnect switch for 30A, 60A, 100A, and
200A ratings does not require adjustment.)

the unit removed from the motor control center or in the
"test" position.
2. The adjustable link rod can adjust to increase or decrease its
overall length by rotating the sleeve. By rotating the sleeve
clockwise the length is increased and by rotating it counter
clockwise the length is decreased. A hex nut is provided as
