  • Page 1 RPT091 Remote Power Transducer QUICK GUIDE BG0227 Rev. A2...
  • Page 2 RPT091 Remote Power Transducer QUICK GUIDE The RPT091 is a compact three-phase AC Remote Power Transducer. The unit operates with a remote master (computer or PLC), and with an optional Remote Display Module (RDM091) for local display/setup. The RDM091 is stand-alone or operable with a remote master, and can be panel-mounted or hand-held.
  • Page 3 DO NOT attempt to open the instrument under any circumstances. 10. Although designed to operate in an electrically noisy environment, the instrument should not be placed near very high electric fields. In the event that the instrument is mounted in a harsh, noisy environment with high potential for electromagnetic impulses from heavy switch gears, motors or lightning, it is recommended to install appropriate protective devices such as...

    3 Electrical Installation 3.1 Power Supply The power source can be dedicated-fused, or from a monitored voltage if it is within the transducer power supply range. AC power supply: line to terminal 12; neutral to terminal 10. DC power supply: positive to terminal 12; negative to terminal 10. Figure 3-1 Locations of Terminals: Front View NOTE: Power source connection requires use of the suppression core provided with the instrument.
