Chapter1Introduction
This reference manual is for the EDMI Atlas series of Energy Meters.
•Mk10 Three Phase Energy Meter (includes Mk10A)
•Mk10D Three Phase Energy Meter with Disconnect
•Mk7A Single Phase Energy Meter
•Mk7C Compact Single phase Energy Meter
•Mk10E High Performance Three Phase Energy Meter
It covers the hardware of the meter, including installation and connections.
The meter is fundamentally an energy meter, measuring the basic quantities of Wh, varh
and VAh. Consumption data may be recorded in a load survey, and as time of use data.
The meter can also measure a wide variety of instantaneous quantities. The
configuration is extremely flexible.
For information on configuring the meter and using it with the EziView software, see
the Atlas Software Reference Manual, 1910-E-07.
Using this Manual
Each chapter covers a specific meter type. While all Atlas meters share a common set
of functionality, the different meter types cover a broad range of metering applications.
Each hardware chapter stands on its own, and does not rely on the contents of other
chapters. The information on the LCD interface of all the meters is covered in Chapter
7“LCD Display”.
Conventions Used in this Manual
All dates are in DD/MM/YY format.
References to settings or controls are printed in Italics.

Information with special note (such as safety information) is marked with a .
Additional noteworthy information is marked with a .
Mk10 Specific information will be marked with a . The name Mk10 refers to
either the Mk10, Mk10D, MK10A, or the Mk10E
Mk7 Specific information will be marked with a . The name Mk7 refers to
either the Mk7A or the Mk7C.
“Clicking” on a button or field means using the left mouse button.
Note that due to variations between computers and improvements in software, the
screenshots shown in this manual may vary slightly from the appearance of the software
on your system.
For more information
The best source of information should generally be this manual. The table of contents
has been organised to make finding information as easy as possible. If you are still
having problems though, EDMI support may be contacted via email at support@edmi-
meters.com The EDMI web site is located at http://www.edmi-meters.com/.
The online help of EziView also has a wealth of information, and contains more
information on advanced functions of EziView such as the scheduler, script files, and
reading files.
When contacting EDMI for support you may be asked for the meter serial number,
firmware version and EziView version. The serial number is printed on the label, and is
the serial number used in EziView to identify the meter. The EziView version is
available under Help

Chapter2The Mk10 Meter
This chapter covers the basic installation and physical features of the Mk10 meter,
including the UPS (Uninterruptable Power Supply), Special I/O and MK10A variants.
Dimensions and Mounting
Figure 2-1 shows the overall dimensions of the meter with a standard terminal cover.
The height excludes the buttons and the ANSI fitting if present.

•Figure 2-1 Overall dimensions of the meter
Height = 210 mm, Depth = 74 mm, Width = 166 mm
Height is 240 mm with an extended terminal cover, such as used to house a modem.

Note that the dimension R4.75 is of the standoff, not of the hole. The lower mounting
holes are oblong rather than round, to allow some adjustment in the meter position. The
76.18 mm dimension is to the centre of this hole.
All dimensions are in mm.

•Figure 2-3 Mounting points, extended terminal cover
For mounting use three screws with a threaded section no larger than 5mm in diameter
with a screw head no smaller than 8mm in diameter.
In general:
1. Screw the first (top) screw into the wall. Leave enough space between the head and
the wall for the plastic around the keyhole.
2. Hang the meter on the screw using the keyhole in the back of the meter.
3. Insert the remaining two screws (meter base, under the terminal cover) to hold the
meter securely.

External Features
Figure 2-4 shows a view of the front of the meter (the specifics of your label will vary).
•Figure 2-4 Front view of the meter with terminal cover fitted
The major parts visible in Figure 2-4 include:
•The LCD display.
•A Select button for cycling the display (bottom push button).
•A sealable Billing Reset button (optional) to initiate a manual billing reset (top push
button).
•Four pulsing LEDs for energy indication (PO1 – PO4) which overlap the first 4
outputs. The special I/O variant has 2 LED’s (PO1, PO2), the UPS variant has 1
LED (PO1) – in these variants the LED’s are independent of the outputs.
•A FLAG or ANSI port for local connection.

The Mk10 Meter 2-5
Beneath the terminal cover (accessible by removing the sealable screw on the top
middle of terminal cover) is the terminal block for voltage and current, connectors for
the pulsing inputs and outputs (optional), the optional RS-232 or RS-485 interface, and
the optional external battery
The sealable screws have 2.15mm diameter holes to accommodate standard sealing
wire.
Under the Terminal Cover
Most of the connections to the meter occur under the terminal cover. Figure 2-5 shows
the terminals available on a standard I/O variant 2 input / 4 output / RS-232 / CT
connected meter.
•Figure 2-5 Under the terminal cover of the meter
Diagrammatically, this is shown in Figure 2-6 with the terminal block numbering.

Table 2-1 lists the terminal block connections, standard I/O variant.
Terminal Description
TB1 RJ45 connector which is hardware configured
to either RS485 or RS232, or a 5 way terminal
block for RS485.
TB2 Voltage and current inputs.
TB3 I/O - PI5 or PO5.
TB4 I/O - PI6 or PO6.
TB5 I/O - PO1.
TB6 I/O - PO2.
TB7 I/O - PO3.
TB8 I/O - PO4.
•Table 2-1 Terminal block connections
Outputs are BOSFETs, up to 240V, 100mA, AC or DC. Inputs are AC or DC in a
range of voltage options. An active input option is not offered on this variant. All I/O’s
are isolated from each other to 2kV, except for active inputs which share a supply with
the modem port. All I/O are isolated from the line (neutral) and TB1 by 4kV.
Special I/O Variant
This variant separates the LED’s from the I/O, and provides more I/O type options.
Figure 2-7 shows the terminal layout, and Table 2-2 lists the terminal block connections.

TB3 I/O - PI3 or PO3.
TB4 I/O - PI4 or PO4.
TB5 I/O - PI5 or PO5.

•Table 2-2 Special I/O Terminal block connections
All 4 I/O can be either SØ Outputs, BOSFET Outputs or 240V/110V/48V/12V/5V
Inputs. PO3 and PO6 have the option of a 2A, 240V relay. TB4 and TB5 should not be
considered as isolated from each other (1mm creepage between them). Isolation of TB1
to TB3, TB3 to TB4 and TB5 to TB6 is 4kV (unless active inputs are fitted, in which
case there is no isolation between TB1 and the active inputs). All I/O are isolated from
the line (neutral) by 4kV.
Mk10A Variant
This variant has similar I/O options to the special I/O variant. Figure 2-8 shows the
terminal layout, and Table 2-3 lists the terminal block connections.

All 4 I/O can be either SØ Outputs, BOSFET Outputs or 240V/110V/48V/12V/5V
Inputs. PO3 and PO6 have the option of a 2A, 240V relay. TB5 and TB6 should not be

UPS Variant
The UPS variant offers UPS backup, and separates the LED from the I/O. Only Active
inputs are available though. Figure 2-9 shows the terminal layout, and Table 2-2 lists the
terminal block connections.

•Table 2-4 UPS Terminal block connections
All 3 inputs are active. Thus there is no isolation between TB1, TB3, TB4, and TB5.
All inputs and TB1 are isolated from the line (neutral) by 4kV. Note in some revisions
of the PCB show +/- indications opposite to the actual board. The right hand terminal of
each pair is the ground connection.
Terminal Spacing
Figure 2-10 gives the terminal spacing of TB2.
•Figure 2-10 TB2 terminal spacings
There are several styles of terminal in use – Table 2-5 summarises their inner
dimensions.

•Table 2-5 Terminal sizes
New Terminal Block
There is an updated terminal block design. This provides shrouding for the current
terminals, numbering on all terminals, external VT to CT links (instead of internal
links), and an optional finger guard. The terminal spacing and locations are unchanged.
Figure 2-11 shows the new layout.
•Figure 2-11 New style terminal block of the meter
Finger Guard
An optional finger guard may be fitted over the TB2 terminal screws in meters fitted
with the new style terminal block. This can help prevent accidental contact with the
supply voltage, as well as allowing these connections to be sealed.
•Figure 2-12 The finger guard in place
Terminal Cover Tamper Detect
The Mk10A meter has an optional switch that can detect the opening of the terminal
cover. It is located above the battery connector. The meter can generate an EFA alarm
