Installation Instructions:
1. Use a volt meter to confirm that you have 240 volts between L1 and L2.
This meter will not function correctly unless this is the case. For 120V
systems, use our any of the EKM-Omnimeter meter models.
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 2 hot Lines and the
neutral line. Label all 3: L1, L2, N.
4. Once the power has been turned off, pass line 1 and line 2 through the
two holes in the meter. (for a retrofit installation this may first require
diconnecting the ends of L1 and L2 from a breaker or junction box)
5. Once the wires are through the meter, the ends should be reconnected
in their orignal positions. On the meter, tighten down the tap screws for
each line that passes through the meter. The tap screw will give the
meter its voltage reference as well as power the meter once the power
is turned back 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.

RS-485 and Pulse Output(Fig 2):
• Terminal 4 (A) connects to RS-485+ or T+ on the RS-485 network.
Terminal 6 (B) connects to RS-485- or T-. Terminal 5 (G) is used for
the RS-485 network (signal) ground if needed. Observe proper RS-485
network topology. Twisted pair wiring is recommended. Shielded
twisted pair may be benificial in electrically noisy environments or for
very long runs. RS-485 supports up to 256 devices on up to 4000 feet
wire. Terminating resistors may be beneficial.
• Terminals 1 and 2 are for pulse output. Pulse rate: 800 Impulse/kWh.
Polarity sensitive. Maximum 27VDC, 27mA.
