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.
Prerequisites
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.
Procedure
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.
5. Use the enclosed metal plug to seal any unused port.
6. Tighten the conduit/cable gland.
7.
The cover on the terminal compartment should be tightened to mechanical stop
(metal to metal). Make sure the cover is fully engaged to meet explosion-proof
requirement and to prevent water from entering the terminal compartment.
