Installation Diagrams

Product Dimensions

This ‘double ended’ type is used when the field instrument has

only a single conduit entry port; the protector attaches to the

instrument, and the connection to the field wiring is made inside

an external, appropriately rated box connected to the other end

of the protector.

The ‘single ended’ protectors are useful for field devices with

dual conduit ports; the field wiring connects to one port while

the 1669 protector connects into the second - all connections

are made within the instrument’s wiring cavity. This installation

simplifies the task of maintenance or of adding a protector into

an existing loop.
