ACT2000 USER GUIDE

Note: It is important that user-supplied end attachments and

connecting hardware align properly with the axis of the
extension rod. Any misalignment will result in a side load on
the extension rod (force applied perpendicular to the axis of
extension rod) as it extends and retracts. Such a side load
will reduce the efficiency of the ACT2000, requiring more
electrical current to achieve a given amount of force or
torque. A side load will also increase the mechanical stress
and friction, increasing the rate of wear on the ACT2000.

The extension rod has wrench flats to counteract mounting hardware
installation torque.

WARNING

Property Damage Hazard – Always use the extension rod wrench
flats when installing mounting hardware. Failure to use the wrench
flats may damage or break the internal anti-rotation guide.

When no power is applied to the ACT2000, its extension rod can be
moved manually, if necessary. Approximately 60 to 100 lbf is required to
extend or retract the extension rod. A rod guide is provided internally to
prevent extension rod rotation.

WARNING

Property Damage Hazard – Do not attempt to rotate the extension
rod. This may damage the internal anti-rotation guide and void the
warranty.
