Installation & Adjustment Procedures
5. Place counterbalance arm directly on the other bearing hub and other intrapole arm on top.
Be certain the angle between the two arms is set correctly. Bolt insulators directly to the
intrapole arm plate.
NOTE: Field assembly of switches with multiple unit insulator stacks is easier when the lowest unit
is mounted first and balance of units mounted to it rather than mount the entire stack as a single
unit.
6. Rotate insulator with switch arm clockwise (facing down) against the stop and attach
intrapole linkage. Be sure length of this linkage is properly set to dimension shown on
drawing.
7. Depending upon its application, this type switch will be counterbalanced either by weight or
by spring. Refer to unit assembly drawing and attach appropriate number of weights – or the
spring – to the counterbalance.
8. On top of stack with the switch arm only, securely bolt the male blade assembly in line with
length of the base.
9. On the other stack, securely bolt the female blade assembly. The switch will have to be
opened slightly to do this.
