• Start current: 0.4% Ib. (1.0)
• Power consumption: ≤1W
• Tamper Detection Class 1.
• Weight: 0.32kg
• Outside dimensions: 78x100x65mm (Fig 1)
Safety Precautions:
• Meter should be installed by a qualied electrician.
• Turn off all power supplying the equipment before preforming any
installation or service. Use a volt meter to conrm power is off.
• Use of this device inconsistent with this manual can cause permanent
damage to the unit and/or serious harm to the installer or operator.
Tools/Materials List:
• Volt meter
• Small standard screwdriver
• DIN-Rail
• UL Listed Type 4 Enclosure (with appropriately rated conduit and
ttings) is required if meter will be installed outdoors
Functions:
• Long-term active electricity measuring without adjustment.
• Meets IEC 62053-21 and IEC 62052-11 standards (static AC active meter)
Installation Instructions:
1. Use a volt meter to conrm that you have 120 volts between L1 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-25IDS v.2 meter.
2. Disconnect or 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 retrot installation this may rst require
disconnecting L1 and neutral from a breaker or junction box)
5. 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.
Pulse Output(Fig 2):
• Terminals 1 and 2 are for pulse output. Pulse rate: 800 Impulse/kWh.
Polarity sensitive. Maximum 27VDC, 27mA.
• Red LED on the meter face ashes 800 times/kWh. 1 ash = 1.25Wh.

Working Principle:
When the meter is working, the energy consumed by the user is transformed into voltage and current signals, which are sampled by sample circuits. A
pulse signal is then produced by a specialized IC. The Pulse signal is directly proportional to power consumption. The MCU records and stores the
corresponding energy 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 go at 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. The process of transportation, handling, and installation should be done according to the transportation and storage rule of
GB/T15464-1995. Keep the meter in the original packaging when stored. The storage temperature range should be 0–40ºC. The relative humidity
should be ≤85%. 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 specications 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.
