Temperature Controller - Staveb AG

Preparations 2-9• Separate input leads and power lines in order to protect theBulletin 900-TC32 and its low voltage sensor and communication linesfrom external noise.• Use AWG 24…14 leads for terminals 1…6 and AWG 28…22 leads forterminals 7…9.• Tighten the terminal screws using a torque no greater than 0.24 Nm(2.12 lb-in.) for terminals 1…6 and a torque no greater than 0.13 Nm(1.15 lb-in.) for terminals 7…9. Loose screws may cause a malfunctionif the wires come out of the terminal.WiringPower SupplyThe controller requires an external power source for operation. Connect toterminals 1 and 2. The following table shows the specifications.Table 2.AInput Power Supply100…240V AC, 50/60 Hz24V AC, 50/60 Hz24V (not polarity sensitive)Bulletin 900-TC324.3 VA @ 120V, 7 VA @ 240V4.0 VA2.5 WATTENTION!Use a power supply matched to the power specifications ofthe Bulletin 900-TC32. Also, make sure that rated voltage isattained within 2 seconds of turning the power ON.Standard insulation is applied to the power supply I/O sections. If rein forcedinsulation is required, connect the input and output terminals to a devicewithout any exposed current-carrying parts or to a device with standardinsulation suitable for the maximum operating voltage of the power supplyI/O section.When mounting a noise filter on the power supply, make sure to first check thefilter’s voltage and current capacity, and then mount the filter as close aspossible to the Bulletin 900-TC32.Publication 900-UM003C-EN-E - January 2004
