In order to allow proper operation and to fulfil EMC requirements, the cable between the RDU 40 and the REX junction box should meet the following requirements:

•Shielded cable. Minimum 3 wires. The shield shall be circular con- nected inside the cable gland of the RDU 40 and connected to ground in the REX junction box.

•All wires must have at least 0.25 mm individual insulation.

•Maximum total length of 100 m, both master and slave included.

•Minimum AWG 20 or 0.5 mm² for each wire.

The RDU 40-chassi shall be grounded locally to the tank. Use minimum 4 mm² or AWG 11 wire. Additional protective ground connection to the power distribution central or the REX junction box is not recommended except where required according to national code of practice. A ground loop with circulating current may occur.

Note!

It is not possible to use an RDU40 and a SDAU simultaneously.

 

 

 

If a cable with two shields is used, one shield shall be connected to

 

ground in the REX junction box and the other shall be circular connected

 

inside the cable gland of the RDU 40.
