EKM-15IDS and EKM-15IDS-N Spec Sheet
Use these meters for accurately measuring 120 volt 2-wire loads
Use if you have easy access to your wires, and if you wires are under
3/8” in diameter. For larger amperages and wire sizes use our
EKM-Omnimeter.

by double insulation as indicated by:
Safety Precautions
•Meter should be installed by a qualified electrician.
•Turn off all power supplying the equipment before perform-
ing any wiring operations. Use a properly rated volt meter to confirm
power is off.
•Use of this device inconsistent with this manual can cause
permanent damage to the unit and/or serious harm to the operator.

Installation Instructions
For All Systems
1. Disconnect or switch power off before attempting to install,
connect, disconnect or service the meter. ALL POWER MUST BE
DISCONNECTED!
2. Mount the meter using 35mm DIN Rail in a protected indoor
location; an enclosure is always recommended.
3. IMPORTANT: Distinguish and then identify the Neutral and the
Line(s) (‘hot’ wire(s), usually black or red). Label the Neutral and
then, depending on your electrical system, assign labels as
described below.
120V, Single Phase, 2-Wire
Wiring Diagram 1: for EKM-15IDS
1. Label hot line - “L” and Neutral - “N”.
2. Pass the L stranded copper wire through the L port (the tube in
the body of the meter. Pass the N stranded copper wire through

EKM METERING http://ekmmetering.com – [phone] – [email protected]
the N port in the meter. If the wire will fit through the provided
centering bushings, then the bushings should be used. These
wires should be passed so that the power flows from bottom of
meter (source side) to the top of the meter (load side). The Neutral
wire will bypass the meter.
3. Tighten down the L wire tap and the N wire tap.
4.Secure the terminal block cover.
Wiring Diagram 2: for EKM-15IDS-N
Both EKM-15IDS and EKM-15IDS-N have 7 digits. Displayed as
99999.99
They also have a pulse output of 800 pulses per kWh
Communications:
For EKM-15IDS-N RS-485: Connect RS-485 A on meter to
RS-485 A on the communication converter. Connect RS-485 b on
meter to RS-485 b on the communication converter. Up to 256 of
these meters can be daisy chain connected to the meter network
on up to 4000 feet of wire.
