Making the Electrical Connection First
The electrical connection may be installed on an adequately supported rigid conduit
system. 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.
