Making the Electrical Connection First
The electrical connection may be installed on an adequately supported rigid conduit sys-
tem. Use suitable locknuts (not provided) when mounting the instrument to an unthreaded
(knockout) hole. Process connection pipe or tubing may be rigid or flexible. Securely
connect the conduit pipe or fitting by holding the hex on the electrical connection while
tightening.
Units in hazardous locations – prior to removal from service, make sure
that the work area is declassifi ed. Failure to do so could result in severe
personal injury or substantial property damage.
Three-conductor shielded cable is provided as standard. If the optional screw terminal
housing was specified, wire according to screw terminal designation below.
