  • Page 3 LIMITED WARRANTY The manufacturer offers the customer an 24-month functional warranty on the instrument for faulty workmanship or parts from date of dispatch from the distributor. In all cases, this warranty is valid for 36 months from the date of production. This warranty is on a return to factory basis.
  • Page 4 The secondary of an external current transformer must never be allowed to be open circuit when the primary is energized. Ensure that the current transformer wiring is made through shorting switches and is secured using an external strain relief to reduce mechanical strain on the screw terminals, if necessary.

  • Page 8: Introduction

    1 Introduction The PM290 is a 3-phase AC Powermeter specially designed to meet the needs of users ranging from electrical panel builders to substation operators. The PM290 performs all basic power measurements; Option L provides ground leakage current measurements (instead of external synchronization).
  • Page 9 Communications Connection (optional) Connection to a printer, computer or central control room is enabled by an RS-232/RS-422/RS-485 communications port that can operate at baud rates of up to 9,600 bps. The RS-422/RS-485 port can operate in multi-drop mode, permitting the connection of up to 32 instruments to a single communications line.
  • Page 10 Getting Started Connect the Powermeter to a suitable power supply. The Powermeter will initiate a series of self-tests. Upon completion of the self-tests, all of the front panel LEDs will light up for one second and indicate a one- digit diagnostic code. An ‘8’ represents normal power up. If a different diagnostic code constantly appears when you apply power to the instrument, contact your local distributor.

  • Page 14 If the instrument is installed in a harsh environment with potential for electromagnetic impulses from heavy switch gears, motors or lightning, then it is mandatory to use the EMI/RFI suppression cores provided with the instrument, connected to the power supply and communication terminals, as shown in Figure 2-4.
  • Page 15 2.2.4 Current Input Connections See Typical Installation on page iv for current input connections. All CTs must be connected in the correct order and with the correct polarity as shown in the wiring diagrams for the instrument to operate properly. If the instrument displays a power factor of zero or close to it, or if power readings show unreasonable values, this may indicate a reversal of polarity of the CT connections.
