Operating Working indicationOn the front panel, there are three power indicating LEDs : yellow L1 phase; green L2phase; red L3 phase. LEDs will light when connected to supply. Consumption indicationPULSE LED is used for indicating power consumption with a flash rate of 400 impulsesper kWh (2.5Wh/imp). Reverse indicationREV. LED will light when supply and load are incorrectly connected (reversed). Reading the meter6+1 register with back light. Pulse outputEnergy meter is equipped with an pulse output that pulses in proportion to themeasured energy for remote reading purposes. The pulse output is a polaritydependant, passive transistor output requiring an external voltage source for correctoperation. For this external voltage source, the voltage (Ui) should is 5-27V DC, andthe maximum input current (Imax) is 27mA DC. To connect the pulse output, connect5-27V DC to terminal 26 (anode), and the signal wire (S) to terminal 27 (cathode). Themeter pulses 400 per kWh (2.5Wh/imp).
