Qonnex17 Quick start 2-Wire v3.0EMM.630(M)CT-MID (1A of 5A CT) andEMM.630MCT-RC (Rogowski coils)The EMM.630 (M)CT is an advanced 3 phaseenergy monitor with direct connection to themains for measuring reference voltages and3 connection for linking the currenttransformers 1A or 5A CT or Rogowski coils(EMM.630 MCT-RC) with which consumerscan be measured >100A. The configurationof the meter is done via the touch keys onthe front panel and the LCD display. The bi-directional measurement measuresconsumption on mono, 3x230V or 3x380V+Npower supplies. Both active and reactive power are measured. Thereadout of the consumption values can be done via the display or on thelinked web server. The module is packed in a 4 module wide DIN railhousing. In addition to an RS485 connection, this energy meter also has 2pulse outputs, of which 1 is configurable.1. Connect:Attention 1: To avoid voltage surge: first connect coil conductors to themeter, only then clip coil around current conductors !! Install the power coilonly by a qualified electrician !!! Wear safety goggles during every operationwith the coils !!!Attention 2: With the EMM.630 CT-MID, the type of coil can only beentered once, see point 2. Configuration on displayAttention 3: After connecting the coils via display key "P" polarity check,if negative power(Watt) or negative PF then open and turn coil, unlessthere would be injection by solar panels!Attention 4: The measured reference voltage and the measured currentmust be at the same stage: ALWAYS test with voltmeter : Voltagebetween conductor reference voltage and conductor flow pool must beZERO, otherwise you have a wrong measurement!! Here you can possiblyuse the voltage drain terminals type UAD (see website)EMM.630 (M)CT: Mono-phase connectionOn display: set as mono phase: SYS 1P2Reference voltage: Neuter on Clamp 1; Phase on Clip 4Flow coil: Keep flow arrow on coil, arrow points to Users!

For this reason, no power islogged in the Memo for this phase2.Rinse L3:Black conductor (=GND) on clip 15; White conductor on clamp 16Power supply voltage: Neuter on Clamp 6; Phase on Clip 5Note : by-loop-Clamp to next meter:Clamp7= Clamp 5; Clip 8= Clamp6Modbus connection: Clamp A (=14) and B (=13) and GROUND (=12 GND)EMM.630 CT: 3x380V+N connectionOn display: set as 3phase/3guider: SYS 3P4Reference voltage: L1 on Clamp 4;; L2 on Clamp 3; L3 on Clamp 2;N=Clamp 1Flow coil: Keep current arrow on coil, arrow points to consumer!Rinse L1: Black conductor (=GND) on Clip 19; White conductor on Clip 20Rinse L2: Black conductor (=GND) on Clip 17; White conductor on Clip 18Rinse L3: Black conductor (=GND) on Clip 15; White conductor on Clip 16Power voltage module: Neuter on Clamp 6; Phase on Clip 5Note: Loop-Clip to Next Meter Clip 7= Clip 5; Clip 8= Clamp6Modbus connection: Clamp A (=14) and B (=13) and GROUND (=12 GND)2: Configuration on the display:This module is partly pre-configured and only needs to be entered: a UNIQUE Modbus address, number between 1... 247 the type of power supply mono,3x230V,3x380V+N, standard at3x380+N the type of coil: be careful, this can only be done once and cannotbe adjusted afterwards!!!How to get into SETUP: (watch video tutorial) https://www.2-wire.net/en/product/3f-energy-meter-ct-mid-modbus-emm-630-ct/)Push the bottom button 4 (enter→)until PASS 0000 appears, fill in defaultpassword PAS 1000 by pressing the button 2 (M↑) to 1, briefly press button4 (enter) for next number or press enter for a long time to move to nextsetting. Go through button 3 (P√) through the set values and adjust thenecessary Modbus values. Briefly press button 1 (U/I ←)) to leave menu.Modbus parameters to be set: 9600 8N1 Modbus address : Id001... Id247 Baudrate: b 9600 Parity: Prty n (parity none) Data: 8 bit Stopbit: 1Secondary current of the coil 1Ampere or 5Ampere: SETCt2 5 At the EMM.630CT-MID this can only be setonce!!Multiplication factor = primary/ to secondary flowstrength of the coil, E.g. 100A/5A=20: Ct rATE 0020With the EMM.630CT-MID this can only be set once!In case Rogowski: CT1 should be set to 1kA, in theEMM.630 MCT-RC meter you can still change settingsafterwardsATTENTION:1. The values SET Pt2 400 and Pt rAtE 0001 arefor high voltage and can only be adjusted once.Leave it on DEFAULT! !2. The backlight of the display can be set to0/5/10/30/60/120.0 stands for continuous, 5/10/30/60/120means switch off after the set period . Herebetter choose 5/10/30 to increase the servicelife.3: Configuration in the web serverIn the web server, go to /configuration/modules: |
