Figure 3-14. Non-IS terminal compartment

The non-IS explosion-proof/flameproof compartment has a terminal block for connecting power supply, communication buses to host systems, relay outputs, and HART 4-20 mA analog input and output.

1. Ensure that the power supply is switched off.

2.Loosen the safety locking screw.

3.Remove the cover on the non-IS terminal compartment.

4.Run the wires through the cable gland/conduit. Install wiring with a drip loop in such a way that the lower part of the loop is under the cable/conduit entry.

5.Connect wires to the terminal block. See Table 3-8 on page 3-25for information on the terminal block connections.

6.Use the enclosed metal plug to seal any unused port.

7. Tighten the conduits/cable glands.

8. Attach and tighten the cover. Ensure that it is fully engaged to meet explosion-proof requirements and to prevent water from entering the terminal compartment.

9. Tighten the safety locking screw.

NOTE!

Ensure that o-rings and seats are in good condition prior to mounting the cover in order to maintain the specified level of ingress protection. The same requirements apply for cable inlets and outlets (or plugs). Cables must be properly attached to the cable glands.
