(minimum) wire must be run from the site earth ground to the STP sump in a non-
intrinsically safe conduit or duct (see Figure 1). DO NOT CONNECT THE CLAMP OR BODY OF
THE PLLD PRESSURE SENSOR TO ANY INTRINSCALLY SAFE WIRE THAT CONNECTS TO
THE TLS CONSOLE.
3. Using the ring terminal supplied in the kit, insert the stripped ground wire into the barrel of the ring
terminal.
4. Use a properly sized crimping tool to ensure a good tight bond (see Figure 2).
5. Place the clamp around the sensor and attach the ring terminal to the clamp with the clamp bolt.
6. Securely tighten the clamp bolt until the clamp tightly grips the sensor body and no longer can be
rotated by hand.
7. Confirm continuity between the PLLD sensor body and ground at the electrical panel and between
the electrical panel to the TLS console chassis (reference Figure 3).
