Installation & Adjustment Procedures
Installation of the EC-2V When Shipped Unassembled
1. Prior to assembly, all components should be checked for any obvious damage in shipment. If
damage is noted, immediately file a claim with the carrier and notify the factory.
2. The preferred method of field assembly is to bolt the switch base directly to its mounting
structure and assemble the switch in place. Refer to the operating mechanism and the unit
assembly drawing to ensure proper positioning of the base.
−
An alternative method is to assembly the switch on the ground and hoist to structure as
a completely assembled unit. To do this:
− Bolt the base to a firm, level surface sturdy enough to prevent overturn. These switches
are top-heavy and very unstable. To prevent possible personal injury or equipment
damage, select an assembly surface that will prevent overturn in both planes, end-to-
end and side-to-side.
3. Refer to the unit assembly drawing. Check jack screw dimensions for proper height. Be certain
that all four jack screws on each bearing are set correctly. Tighten jam nuts securely.
4. To install insulators, refer to the unit assembly drawing for proper orientation of parts. Only one
set of bearing stops (positioned on control end of base) is used. Position switch arm directly on
hub of bearing with bearing stops. Place an intrapole arm on top, being careful to set at proper
angle with respect to the switch arm when against the bearing stop. Bolt insulators directly to
the intrapole arm plate (
