Installation & Adjustment Procedures
Mounting Live Parts on Insulators
Horizontal Mounted Switch
1. After stacking insulators, turn the rear-rotating insulator counterclockwise to the
fully open position against the bearing stop. Mount the live parts with the blade
still in the fully open position (See
). Lift the hinge end live parts with the
strut.
2. Tighten lower bolts on rear rotating insulator stack.
Vertical or Underhung Mounted Switch
Follow the above procedure except:
1. Turn the rear, rotating insulator clockwise against the bearing stop to the fully
closed position.
2. Mount the live parts with the blade in the closed position.
Adjustment of Switch in Open Position
Horizontal Mounted Switch
Refer to the single-pole sub-assembly drawing for the correct angle of blade
opening. If adjustment is required, use the open position stop cam on the strut to
adjust the blade until it is at the required angle (See
). Now tighten upper
rear rotating insulator bolts.
Figure 4: Switch Adjustment in Open Position
Do not use the blade or fork as a lifting point for the live parts. The hinge
end of this switch has threaded contact joints and may be damaged if lifted
improperly.
