Installation:

HIGH VOLTAGE WIRING:

Always turn the power off before installation -installation should only be performed by a qualified electrician

These meters should be installed in a protected location. Such as a sub panel or electrical enclosure. If you are planning on using your own enclosure, we supply 3” pieces of DIN rail ($2) that make for an easy install. Once your meter is properly wired, you can clip the meter to this DIN rail. We also provide indoor and outdoor enclosures here: Meter Enclosures.

Each meter draws less than 1 watt of power

Our EKM-Omnimeter is just one meter model that can be used to meter a range of metering system types and amperages. Use the videos below to demonstrate proper wiring for each electrical system.

 

WIRING VARIATIONS:

120 volts 1 hot and 1 neutral - the CT goes around the hot wire (usually the black wire, check this to make sure) Requires 1 CT

120/240 volts -- 2 hots and 1 neutral - the CT goes around the hot wires (usually the black and red wires, check this to make sure) Requires 2 CTs

3-phase 3-wire -- 3 hots - the CT goes around any 2 of the hots Requires 2 CTs

3-phase 4-wire -- 3 hots and 1 neutral -- the CT goes around all 3 hots. Requires 3 CTs

OTHER SMART METERS:

EKM-Omnimeter Pulse v.4 -- This meter is for counting pulses from up to 3 Pulse Output Water and Gas meters, as well as controlling 2 loads. You can use this meter to remotely read your electricity, water, and gas consumption over the internet. You can also use it to control 2 loads, switches, alarms, relays, etc. remotely as well.

The EKM-Omnimeter Pulse v.4 has 3 pulse counting inputs so you can keep track of up to 3 separate pulse output devices.

Click here: Pulse Input Electric Submeter -- to see more information on the pulse counting meter.

 

VOLTAGE REFERENCE:

The electrical meter needs a power connection coming from the main lines you are metering. This can be 16 AWG stranded copper wire. The meter itself draws less than a watt of power. A 1amp inline fuse is recommended in the hot lines that power the meter. This would be a precaution to protect your meter from spikes that might cause damage.

For the voltage reference, CT wires and communication wires: Make sure when you are connecting this wire to the meter, to first back off the screw all the way then insert the wire then tighten down the screw, sometimes it is hard to notice you have the wire on the wrong side of the terminal clamp.

CT 1 Should be on Line 1 and the meter should also get its LIne 1 voltage reference from Line 1, Same for Line 2, etc.

Wiring diagrams are laser printed on the body of the meter and are supplied with the spec sheet for each meter.

CT Wires and Electrical wires should be protected from the elements and the sun by using electrical conduit. A meter enclosure is also recommended.

 

Communications:

RS-485 INSTALL:

RS-485 Wire -- We use twisted pair wire, you can find 4 pairs of 24 AWG twisted wire inside of a CAT5 cable. CAT5 is perfect because it is easy to find, comes in 1000 foot rolls, its cheap, and easy to pull the wire for installations. Stranded CAT5 is the best, but solid copper can also be used. Use one of the twisted pairs, then you will have some extra wires to use in the future. RS-485 allows you to daisy chain up to 256 meters together on up to 4000 feet of wire. Use one twisted pair of wire for your RS-485 system. One wire is RS-485 A+ (solid orange) and the other is RS-485 B- (white with orange). Make sure when you are connecting this wire to the meter, to first back off the screw all the way then insert the wire then tighten down the screw, sometimes it is hard to notice you have the wire on the wrong side of the terminal clamp. For very long runs in electrically noisy environments, it will be better to use shielded twisted pair wires. Some installations require a 120 ohm terminating resistor, we have not found this to be important for most installations.

 

TWISTED PAIR WIRE CONNECTIONS:

iSerial: Connect RS-485 A+ on all meters to T+ on iSerial, Connect RS-485 B- on all meters to T- on iSerial, GND is not necessary.

RS-232 Converter: Connect RS-485 A+ on all meters to A on RS-232 Converter, Connect RS-485 B- on all meters to B on RS-232 Converter

USB Converter: Our new tiny USB Converter works well with all meters, A+ connects to A+ on the meters. B- on the USB converter connects to B- on the meter.

    EKM Dash Software

Our new user-friendly software allows you to read meters which are connected to your computer, whether it be a PC, Linux box, or a Mac running OS X, and whether the meter is connected directly with one of our USB to RS-485 converters, over a LAN network, or over the internet with the iSerial TCP/IP to Serial Converter. From this application you can, read all of the meter parameters, set meter numbers (addresses), set passwords, reset demand to zero, and, have meter usage logged to a file and have monthly reports e-mailed to individual users or formatted for printing and mailing. This is a direct replacement for our legacy EKM Reader software. It features all of the same functionality and more, in a much more stable and easy to use package.

Try a free 30-day trial. Download your copy with the links below.

EKM Dash For Windows

EKM Dash For Mac

EKM Dash For Linux

This is a completely new software build that is intended to be a direct replacement for our legacy EKM Reader software. The current version is still in development and should be considered a Beta release. We continue to make adustments to increase stability and we plan on adding a lot more features and functionality in the future. As it is still in Beta, we would appreciate any feedback that you can give us on your experience with it. It will work with both our v.2 and v.3 meters. The software is pre-configured to read a few test meters here at EKM Metering. For reading your own meters, just make the appropriate preferences and other configuration changes.

We are relasing our dashboard today as a free 30-day trial. you can also purchase a registration key in our online store here: EKM Dash Registration Key. This key will give you unlimited use of the unrestricted EKM Dash. After the free 30-day trial is up the software will still be usable but will lose some of its funtionality, like the ability to log data or send emails. The urestricted version provides logging of meter reads to .csv files. It also can generate automatic monthly reports emailed to individual meter users. Once purchased, all updates to the software are free.

The software will work with V.2, V.3, and v.4 smart meters. Meter reads give Total kWh, Reverse kWh and Maximum Demand, plus Instantaneous Current, Voltage, Power, Power Factor, as well as 6 months of monthly records stored on board the meter, including 4 Time-of-Use Rates for 4 Daily Time Periods and 6 Seasons.
