Installation instructions: 1. Use a volt meter to confirm that you have 120 volts between Ll and neutral. This meter will not function correctly unless this is the case.. If there are two hot lines and there is 240V between them, you have a 120/240V system: In this case you will use an EKM-251DS v.2 meter. 2. Discuunect ur switch power off before attempting to install, connect, disconnect, or service the meter. ALL POWER MUST BE TURNED OFF! 3. IMPORTANT: Distinguish and then identify the hot Line and the neutral line. Label both of them. 4. Once the power has been turned off,, pass line 1'through the hole on the right of the meter and pass the neutral line thought the hole on the left side of the meter. (for a retrofit installation this. may first require disconnecting Ll and neutral from a breaker orjunction box) S. Once the wires are through the meter the ends should be reconnected in their original positions. On the meter, tighten down the tap screws for each line that passes through the meter. The tap screws penetrate the wire insulation and power the meter once the power is turned on. 6. Mount the meter using 35mm DIN Rail in a protected indoor location. If installing outdoors, a UL Listed Type 4 Enclosure is required. 7. Once the above steps are completed, and you are ready, you can turn the power back on and begin to read your meter.

H pulse signal is then produced by a specialized IC. The Pulse signal is directly proportional to power consumption.The MCU records and stores the correspondingenergy use. The LCD screen displays the energy use. Data: The LCD display shows one piece of data: total electricity consumed(kWh). By design the kWh cannot be reset.The meter will goat least 10 years without power and still keep Its kWh readings. In other words, the memory will not be erased if there is no power. Transport and Handling: The meter should be handled with care, as there are precision components inside that could break and/or cause faulty readings should the meter become damaged. Theprocess of transportation/handling, and installation should be done according to the transportation and storage rule of GB/T1.5464-1995. Keep the meter in the original packaging when stored.The storage temperature range should be 0-40°C.The relative humidity should be 565%. There should be no toxic chemicals present and no corrosive substances or gases in the air. The meters should be stacked on a platform no more than ten units high. Warranty: Within two years from the date of sale, and on the condition that the user abide by the specifications and installation instructions listed here, and the sealing is kept completely intact. If the meter does not correspond with the rule of the enterprise standard, the meter shall be repaired free or replaced. Wiring Diagram: The diagram shown below is also marked on the meter body. Qtv�� ' o (Fig 4) Specifications: • Model: EKM-IENC • Dimensions: 6.75"Tall x 4.5- Wide x 2.5" Deep • Weight:1 Lb 6oz • Materials: ABS plasic box and covers, steel hardware • Meters Supported: Any electric meters designed by EKM.Metering, including up to four EKM-15E(note that even four of these will not fill the faceplate hole in the enlosure covers). Surface Mount Parts: #1: Hex Nut #2u Lock Washer 43: Small Bolt O O #4: Cover Screw #5: Enclosure Box x2 x2 x2 x4 #6: DIN Rail #1 #2 #3 #4 #7: Surface Enclosure Cover Principle: This setup is Intended for indoor surface mount applications. The enclosure should be attached to a surface in an appropriate way at the discretion of the installer. Any electrical, current transformer, or communication wires should be routed to the enclosure via conduit. There are.two threaded ports for conduit to enter on the top, bottom, and rear of the enclosure box. Installation Instructions: 1. First choose a suitable surface to mount your enclosure on and find a good wayto attach the Enclosure Box(95) to the surface. For example, this can be done by drilling through the back of the enclosure box and screwing to a wooden structural member. 2. Before you mount the enclosure to the surface you will need to attach the DIN rail(46) inside the Enclosure Box.To do this, Insert the Hex Nuts(91) into the recesses in the back of theenciosure. This will hold them in place. Now pass the Small Bo(t(43) through the. Lock Washer(#2),.through the DINRail(#6), and through the Enclosure Box, into the Hex Nut(#1). Use a screwdriver to tighten the bolts. 3. Now mountthe enclosure to the surface you have chosen. 4: Route all of the wiring to the enclosure before you install your meter. 5. Connect thewires to your meter before you clip it onto the DIN rail. 6. When you.have wired up your meter, clip it onto the DIN rail.This is done by inserting the top of the meter first: Then pull down on the spring loaded clip atthe bottom to get it to go behind the bottom of the .DIN Rail. If this is done correctly the meter should now be securely mounted. 7. At.this point you can turn the electricity on and make sure that your meter powers an and that you are getting good reads. If you are using, a smart meter youcan also test that your meter is communicating properly. S. When you are satisfied that everything is connected appropriately you can install the Surface Enclosure Cover(47) using the four Cover Screws(#4) and you should now be finished Installing your meterand Indoor Enclosure. ry - �31 L eS 'Sra1 D LtC� t 'w N I �t a5t a�15 nftf c3� 1 a,7 s t la N a1Fk-� j I Gr—�Jr_ Mhdie-0 r LIJU0 n1 4LOl Riq loot Fp2r PirRcF, rL. 341116 =RECEIVED
