1 EM341 Intallation and ue intruction 65 A direct connection three-phae energy analyzer with Modbu and digital interface General warning HAZARD: Live part. Heart attack, burn and other injurie. Diconnect the power upply and load before intalling the analyzer. Protect terminal with cover. The energy analyzer hould only be intalled by qualified/authorized peronnel. Thee intruction are an integral part of the product. They hould be conulted for all ituation tied to intallation and ue. They hould be kept within eay reach of operator, in a clean place and in good condition. Decription The analyzer meaure active and reactive energy, umming (eay connection mode on) or eparating imported energy from exported energy. It manage up to four energy tariff uing RTC and calendar. It i equipped with two digital output (pule or alarm output) and an RS485 Modbu port. It meaure three DIN module, with backlit LCD diplay with enitive touch creen area for page crolling and parameter etting. Code key (analyzer ide) EM341-DIN. AVx. 3. X. OS. X Model AV2: V L-L ac, 5 (65) A, direct connection Three or fourwire three-phae current ytem; twophae current ytem, 3-wire Selfpowered (via meaured voltage) Output type: OS: dual digital output and Modbu RS485 port No option included EM CARLO GAVAZZI Control S.p.a 1

DC voltage (V off ) mut be le than or equal to 80 V. RS485 Modbu with Mater Note: additional intrument with RS485 are connected in parallel. The erial output mut only be terminated on the lat network device connecting terminal A- and T. For connection longer than 1000 m ue a ignal repeater. Maximum 247 tranceiver on the ame bu. Connection check The analyzer check whether connection are correct and ignal any fault. The check can be diabled uing the Intall parameter, ee "Parameter menu" on page 9. Initial aumption The check i baed on ome initial aumption on the ytem to be meaured. Specifically, it i aumed that each ytem phae i characterized by: a load with PF>0.766 (<40 ) power factor if inductive or PF>0.996 (<5 ) if capacitive current at leat equal to 10% rated current (65A) Control and ignal Following are the control in the order in which they are run and correponding ignal: Control Decription Voltage order of the involved phae Current direction * + of the involved phae NOTE *: control only run if the imported and exported energie are meaured eparately (Meaure = b) EM CARLO GAVAZZI Control S.p.a 4
