Wiring

The terminal compartment has a terminal board for connecting communication buses to host systems
and field devices. The terminal compartment also has a connection for power supply. Three Ethernet
connections are available for LAN communication.
1. Ensure that the power supply is switched off. Note! If any uncertainty exists whether power supply is
off or not, make sure that loose cable ends don't run through the cover on the power board.
2. Loosen the two captive screws and open the lid (see
the housing for easier access when open more than 25°. Remove the locking ring and carefully slide
the lid upwards 21 mm or more. Be careful not to drop it on the floor.
3. Run wires through a cable gland. Install wiring with a drip loop in such a way that the lower part of the
loop is under the cable entry.
4. Connect wires to the terminal block.

5. Use the enclosed metal plugs to seal any unused cable entries.
6. Tighten the conduits/cable glands.
7. Make sure that the Lock ring on the cover to the communication board compartment is folded so that
it does not prevent the lid from being properly closed. Attach the lid in case it was removed from the
housing and close it. Torque the two screws to 4Nm (35 in.-lb). Ensure that it is fully engaged to
prevent water from entering the terminal compartment.
Note
Ensure that gasket 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.
