EM330 Instaation and use instructions Three-phase energy anayzer for indirect connection (5A) with Modbus, puse or M-Bus interface Code 8021422 Genera warnings HAZARD: Live parts. Heart attack, burns and other injuries. Disconnect the power suppy and oad before instaing the anayzer. Protect terminas with covers. The energy anayzer shoud ony be instaed by quaified/authorized personne. These instructions are an integra part of the product. They shoud be consuted for a situations tied to instaation and use. They shoud be kept within easy reach of operators, in a cean pace and in good conditions. Description The anayzer measures active and reactive energy, summing (easy connection mode on) or separating imported energy from exported energy. It manages two energy tariffs using a digita input or Modbus command. It can be equipped with an optiona output to communicate measurements: puse output, RS485 Modbus port or M-Bus port. It measures two DIN modues, with backit LCD dispay with sensitive touch screen areas for page scroing and parameters setting. Code key (anayzer side) EM330-DIN. AVx. 3. a. a1.

Connection check The anayzer checks whether connections are correct and signas any fauts. The check can be disabed using the Insta parameter, see "Parameters (Fig. 17)" on page 9. Initia assumptions The check is based on some initia assumptions on the system to be measured. Specificay, it is assumed that each system phase is characterized by: a oad with PF>0.766 (<40 ) power factor if inductive or PF>0.996 (<5 ) if capacitive current at east equa to 10% rated current (primary current transformer) Contros and signas Foowing are the contros in the order in which they are run and corresponding signas: Contro Signa Votage order Votage and current correspondence. x, y = number of current phases connected to a non corresponding votage. Current direction *. Check phase 1 first, then 2 and asty 3. x = number of phases invoved in the faut xy x NOTE *: contro ony run if the imported and exported energies are measured separatey (Measure = b). 8021422 EM330 2014 CARLO GAVAZZI Contros SpA 5
