3.4.12 IS Connection

The IS compartment has a terminal block for connecting the intrinsically safe Tankbus for communication with field devices on the tank. This terminal block is also used for intrinsically safe HART 4-20 mA analog input/output communication.

1. Make sure that the power supply is switched off.

2.Remove the cover on the IS terminal compartment.

3.Pull the cable through the cable gland/conduit. Install cables with a drip loop in such a way that the lower part of the loop is under the cable/conduit entry.

4.Connect wires according to Table 3-11 on page 3-29.

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

6.Tighten the conduit/cable gland.

7. Attach and tighten the cover. Make sure that the cover is fully engaged to meet explosion-proof requirements and to prevent water from entering the compartment.

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.
