ELECTRO COMPOSITES (2008) ULC bushings can be installed at any angle. A proper
gasket is required between the flange and the equipment. In case of mounting
problems, contact ELECTRO COMPOSITES (2008) ULC for further corrective action.
Do not for any reason modify or alter any part of the bushing, including the aluminum
flange.
When bolting the bushing to the equipment, tighten each bolt no more than a half turns
at a time. Follow a criss-crossing bolt tightening sequence as shown in the figure below.
Please refer to the bushing drawing for proper flange bolt tightening torque. By using
the proper tightening torque for the bolt size used and the tightening sequence provided,
flange damage and sealing problems from improper tightening and uneven pressure on
the gasket can be avoided. The use of a calibrated torque wrench is recommended.
Before tightening, insure that the conductor terminal ends are free to move since as the
flange is tightened, a small displacement at the flange will cause a much larger
displacement at the terminal ends. Potential damage to the bushing and equipment is
possible if this is not done.
