5.6.1 Cable Specifications
Number of wires in cable varies depending on the number of contact used.
5.6.2 Wiring Procedure
(1) M4 screws are used for the terminals of the converter. Each wire in the cable should
be terminated in the corresponding crimp-on terminal.
(2) The capacities of the contact output relay are 30 V DC 3 A, 250V AC 3 A. Connect
a load (e.g. pilot lamp and annunciator) within these limits.
