Choose the most appropri-ate method depending on the installation conditions. The set of connector forwire-pressed terminal cable is supplied with the unit.Cable with pressure connectionterminal (40 pins)CT-2 connector terminal (40 pins)Used twice for each unitRT-2 relay terminalUsed four times foreach unit, a two-branch cable isneeded for connect-ingConnector forwire-pressedterminal cable(40 pins)Used twice foreach unitFlat cable withconnector(40 pins)Used twice foreach unitWhen using connector for wire-pressed terminal cable(supplied with the unit)You can directly connect wires from AWG 22 (0.3mm 2 ) and AWG 24 (0.2mm2 ).Eliminates the bother of wiring connections because the wires can be connected with-out removing the covers from the wires.Can correct wiring mistakes easy.A tool exclusively designed for this purpose is necessary.For detailed information section 4.4.2When using connector and relay terminalsCan be connected using exclusive cables.With the RT-2 relay terminal, you can control up to 2A.For detailed information section 4.4.3next page
