2 Installation Getting Started - Bulletin 150 SMC Dialog Plus™ Controller The open-style design of the SMC Dialog Plus controller requires that it be installed in an enclosure. The internal temperature of the enclosure must be kept within 0°C to 5 °C (32 °F to 12 °F). The controller is convection cooled. It is important to mount th controller in a position that allows air to flow vertically through the power structure. Allow for a minimum of six inches (15 cm) of fre space around all sides of the controller. Wiring Power Wiring Refer to the product nameplate for power lug termination information including: • Lug wire capacity • Tightening torque requirements • Lug kit catalog numbers (97-1000A Control Wiring Refer to the product nameplate for control terminal wire capacity and tightening torque requirements. Each control terminal will accept maximum of two wires. The SMC Dialog Plus controller accepts control power input of eithe 100-240 V AC, (+ 10/-15%) single-phase, 50/60Hz or 24V AC/DC. Refer to the product nameplate prior to applying control power. Connect control power to the controller at terminals 11 and 12. The control power requirement for the control module is 40 VA. For controllers rated 97-1000A, control power is also required for the heatsink fans as defined in Table C. Depending on the specifi application, additional control circuit transformer VA capacity may be required.
