3.3.4 Wiring for Contact Output
The converter supplies contact signals of either <failure>, <maintenance> or <range>, for which
contact output wiring is provided.
For the wiring, use a cable or 6 to 12 mm finished O.D. (select a two-, three- or four-conductor
cable depending on the number of contract outputs used.)
Treat the cable end to be connected to the converter terminals in the same manner as the analog
output signal cable (see subsection 3.3.2.)
Connect each conductor of the cable to terminals F1, F2 (contact output <failure>), M1, M2
(contact output <maintenance>) and O1, O2 (<range> switching contact), respectively.
Contact capacity of the contact output relay is given in Table 3.2. Equipment to be connected
must meet the condition shown by the table.
