Cable 2
On the EK260 the terminals “R+”, “R-“, “T+” and “T-“ are also labelled with “CS”, “RD”,
“RS” and “TD”. When connecting the FE260, these designations have no significance. The
terminals “Ri” and “Gnd” on the EK260 remain unconnected.
The cable designations (Cable 1 and Cable 2) and the suggested core colours are based
on the use of two similar cables, LiYCY 4 x 2 x 0.5 mm², twin-twisted with colour code
according to DIN 47100. Suitable cables can also be obtained from Elster-Instromet (see
II-2, Options).
With "AC" versions (with 230V or 115V power supply) the blue and red wires of Cable 1
remained unused. They should then be cut off at both ends flush with the cable sheath or
safely insulated to prevent hazardous short circuits from forming.
Of course, other cables can also be used provided they conform to the requirements
quoted in 0. Similarly, a different designation of the core colours is possible.
