Installation Notes
The installation must comply with local and national regulations concerning the
compressed air supply and the SVI FF instrument.
Installation and maintenance must be performed only by qualified personnel. Repairs
to the SVI FF beyond the scope of this manual must be performed by the factory.
Area Classification, Protection Type, Temperature Class, Gas Group, and Ingress
protection must conform to the data indicated on the label.
Wiring and conduit must conform to all local and national codes governing the
installation. Wiring must be rated for at least 85º C (185º F) or 5º C (41º F) above
maximum ambient, whichever is greater.
Approved wire seals against ingress of water and dust are required and the 1/2" NPT
fittings must be sealed with tape or pipe dope in order to meet the highest level of
ingress protection.
To avoid injury or the process being affected when installing or replacing a positioner on a
control valve, ensure that:
If the valve is located in a hazardous area make sure the area has been certified as
safe or that all electrical power to the area has been disconnected before removing
any covers or disconnecting any leads.
Shut off air supply to the actuator and to any valve mounted equipment.
Ensure the valve is isolated from the process by either shutting off the process or using
bypass valves for isolation. Tag shutoff or bypass valves to guard against a
turn-on
while work is in progress.
Purge air from actuator and check that valve is in its unenergized position.
