The extension rod has wrench flats to counteract torque when installing mounting hardware. It
is important to note that the extension rod will rotate if allowed or forced to do so. There is no
anti-rotation mechanism inside the actuator. It is the responsibility of the user to
accommodate this lack of anti-rotation in the choice of connection hardware and in the design
of mounting brackets and linkages. It is strongly recommended to utilize the wrench flats on
the end of the rod in the linkage connection to prevent rod rotation.
WARNING
Explosion hazard – Always use the wrench flats instead of gripping the
extension rod outer diameter as this can cause damage to the extension rod.
Failure to use the wrench flats may invalidate the device’s hazardous area
certification.
Installation - The actuator must be installed in a way that will prevent the
extension rod from rotating during operation. If the rod rotates, the positioning
will be inaccurate, and can cause malfunction such as control “chattering” due
to the inability to extend or retract fully after the rotation.
1.4 Electrical connections
The ACT1000/ACT1000HF is designed for use in hazardous locations. See the general
specification summary in Section 1.2 for certifications. Ensure compliance with the factory
recommendations and that wiring is in accordance with local requirements.
WARNING:
Ex (ATEX and IECEx) compliance – conditions of certification:
1. Protective earthing connection is through a ¼-20 UNC 2B bolt hole, effective
connection must be made and the materials of the bolt must be protected
against corrosion.
2. For the protective earthing connection mentioned in condition 1, if any
components are made of a light metal, special precautions should be made,
for example, using an intermediate part made of steel when making a
connection to a material containing light metals.
Ground connection
The ACT1000/ACT1000HF housing features a dedicated threaded hole (0.250-20 UNC - 2B
female thread) for the ground connection. Surrounding the threaded hole is a pad that is
electrically conductive to the case.
Appropriate wire connection hardware and a 0.250-20 UNC - 2A screw should be used to
connect the case of the ACT1000/ACT1000HF to the same ground plane as the user’s
