Installation & Adjustment Procedures
Final Switch Adjustments (Tuning)
1. The operating mechanism is intended to fully open and fully close the disconnect switch by
rotating the vertical operating pipe about 180
o
using an operator (manual or electrical). The
interphase pipe controls the individual operation of each switch pole, using a push/pull
control. The reach rod translates the motion of the vertical operating pipe to the interphase
linkage. The adjustable arm controls the total amount of switch operation available.
HINT:
For easiest adjustment start with the reach rod connected to the drive phase and
the interphase pipe disconnected from the other two phases. Once the drive phase is
properly adjusted, connect the interphase pipe and continue tuning the other two phases,
one at a time.
2. Switch Operating Devices:
2.1. Worm gear operator (HOGO – High Output Geared Operator) (Optional)
2.1.1. The weight of the vertical operating pipe should be supported by pipe collar ( Figure
13 ) by maintaining the 1/4” - 3/8” gap ( Figure 14 ).
2.1.2. When the switch is properly adjusted the operator handle should hang freely in
both the open and closed positions to permit the use of a customer supplied
padlock. Refer to Figure 14 .

2.2.1. The weight of the vertical operating pipe should be supported by pipe collar by
maintaining the 1/4”-3/8” gap.
2.2.2. When the switch is properly adjusted the operator handle should hang freely in
both the open and closed positions to permit the use of the customer supplied
padlock.
