WiringConnect the external control cables to the applicable module terminals. Ground the outershield of the cables 360 degrees under a grounding clamp on the grounding shelf of thecontrol cables.Motor thermistor connection example60611)CMOD-02PTC INPTC INOne or 3…6 PTC thermistors connected in series.1)The PTC input is reinforced/double insulated. If the motor part of the PTC sensor and wiringare reinforced/double insulated, voltages on the PTC wiring are within SELV limits.If the motor PTC circuit is not reinforced/double insulated (ie, it is basic insulated), it ismandatory to use reinforced/double insulated wiring between the motor PTC and CMOD-02PTC terminal.Relay output connection example6263CMOD-02CCU3435X4363738OUT1OUT2SGNDIN1IN2RO PTC CROPTC BPower supply connection example40411) +-24V AC/DC + in24V AC/DC - inCMOD-02External power supply, 24 V AC/DC1)WARNING!Do not connect the +24 V AC cable to the control unit ground when the controlunit is powered using an external 24 V AC supply.Optional I/O extension modules 283
