Installation
Energy Use indicator
We recommend that the connecting wire which is used to connect the meter to the outside circuit should be sized according
to local codes and regulations for the capacity of the circuit breaker or over current device used in the circuit.
An external switch or a circuit-breaker should be installed on the inlet wire, which will be used as a disconnection device for
the meter. And there it is recommended that the switch or circuit-breaker is near the meter so that it is more convenience for
the operator. The switch or circuit-breaker should comply with the specifications of the building electrical design and all local
regulations
An external fuse or thermal cut-off which will be used as a over-current protection device for the meter must be installed on the
supply side wire, and it is recommended that the over-current protection device is near the meter so that it is more convenience
for the operator. The over-current protection device should comply with the specifications of the buildings electrical design and
all local regulations.
This meter can be installed indoor directly, or in a meter box which is waterproof outdoor, subject to local codes and regulations.
To prevent tampering, secure the meter with a padlock or a similar device.
The meter has to be installed against a wall which is fire resistant.
The meter has to be installed in a good ventilated and dry place.
The meter has to be installed in a protection box when placed in dangerous or dusty environment.
The meter can be installed and used after being tested and sealed with a letter press printing.
The meter can be installed on a 35mm DIN rail.
The meter should be installed in an available height so that it is easy to read.
When the meter is installed in an area with frequent surges due to e.q. thunderstorms, welding machines, inverters etc,
protect the meter with Surge Protection Devices.
After finishing installation, the meter must be sealed to prevent tampering.
Connection of the wires should be done as below:-

5A. TYPE OF CABLE TO USE
The M-Bus uses two wire cables which are going from the M-Bus Master / Repeater to each
M-Bus device (bus structure).
The M-Bus is polarity independent and needs no line termination resistors at the end of the cables.
Any cable type may be used as long as the cable is suitable for 36 V / 500 mA.
Shielding is not necessary and not recommended since the capacitance of the cable should be minimized.
In most cases a standard telephone cable is used which is a twisted pair wire with a diameter of 0.5 mm
each (2 x 0.8 mm is also suitable). This type of cable should be used for the main wiring.
For the wiring to the meters from the main wiring (last 1 .. 5m to the meter) a cable with smaller diameter may be used.
5B. M-BUS BASICS
The topology of the M-Bus network is (almost) arbitrary. Only the ring
topology as shown should be avoided. In general the length of the
cables should be minimized and a mixture between star and bus
topology should be used.
The limiting parameters in M-Bus networks are mainly the cable
resistance and the cable capacitance plus the capacitance of the devices
(= bus capacitance). Cable resistance will cause, a bus voltage drop.
The maximum drop may not be more than 11 V .. 12 V, as the
minimum bus voltage at any device must not be lower than
24 V (36 V – 24 V = 12 V).
The cable resistance, therefore, limits the maximum possible cable length from the MBus Master / Repeater to the device with
the largest distance away from it (largest cable segment). The cable segment length is the distance from the M-Bus Master to
the M-Bus device furthest away.
NOTE: The given maximum cable segment length takes into account only the bus resistance and not the bus capacitance.
Therefore, some of the cable lengths in the table may not be possible in reality.
The cable capacitance plus the capacitance of the M-Bus devices (= bus capacitance) is responsible for sloppy signal edges.
Therefore, the bus capacitance limits the maximum data transfer rate of the M-Bus. The M-Bus Master is able to drive approx.
0,8 µF at a baud rate of 300 baud.
5C. BAUD RATE & BIT RATES
Bit rate is a measurement of the number of data bits (that's 0's and 1's) transmitted in one second. A figure of 2400 bits per sec
means 2400 zeros or ones can be transmitted in one second, hence the abbreviation 'bps'. Baud rate by definition means the
number of times a signal in a communications channel changes state.
Common Settings for M-bus - 300 or 2400. Parity (Error Checking) is EVEN or NONE.
ALL items MUST have the same settings otherwise they CANNOT communicate.

QUICK PROGRAMMING GUIDE
Connect mains power to the meter –
Live to the small terminal labelled 27 at the lower left
Neutral to the large terminal labelled N at the upper right
Switch the power on and wait until the meter completes startup (after it shows the CT ratio)
Press and hold the “PRG” button for 3 seconds – the display will show “PS 0000”
Press the “SEL” button once so that the display changes to “PS 0001”
Press and hold the “PRG” button for 3 seconds to enter the password
If the password was correct (default = 0001) the meter is now in programming mode
The first item is “Id” which is the Mbus address and is in 2 digit hexadecimal format
Use “SEL” to increment the address and “PRG” to move to the next item
The next item is “bd” which is the Mbus baud rate. There are 5 possible values –
0600, 1200, 2400, 4800 & 9600
Use “SEL” to increment the baud rate and “PRG” to move to the next item
The next item is “Sn” which is the number of parameters to show on the scrolling display and is in 2 digit
hexadecimal format. The default value is “0E” but due to a software bug the maximum value that can be set when
it is altered is “0d”.
Use “SEL” to increment the value and “PRG” to move to the next item
The final item is “Cr” which is the CT ratio. This value is multiplied by 5 to give the CT current rating.
There are 27 possible values –
1, 2, 5, 8, 10, 12, 15, 16, 20, 24, 30, 40, 50, 60, 70, 80, 90,
100, 110, 120, 130, 140, 150, 160, 170, 180 & 190
Use “SEL” to increment the value
Press and hold the “PRG” button for 3 seconds to save the settings – the display will show “YES” to confirm that they
have been saved.

TROUBLE SHOOTING
The power supply
indicators are off.
(L1, L2 & L3 LED)
The register
doesn’t count.
No pulse outputs.
The pulse output rate is
incorrect Please contact technical support.
Are the fuses or/and surge protection
defect?
Make sure the wires are connected properly
and tighten the screws if possible.
Check if there is 230V AC voltage between N
and one of the L connections with a voltage
meter.
Check if there is 400V AC volt between N and
one of the L connections with a voltage meter.
If the checks above don’t solve the problem,
please contact technical support.
The meter is not connected to a
power source
L1, L2, L3 and N are not connected
correctly
There is no 230V AC between the N
and one of the L connections when
power is supplied to the meter.
There is no 400V AC between the L
connections when power is
supplied to the meter.
There is almost no load connected to
the meter.
The pulse output is not supplied with
DC power.
The pulse output is not connected
correctly.
Still no response.
Check if the (P-: red or P+: green) consumption
led is flashing. 40 flashes of the LED at 400
pulses per kWh equals 0.1kWh.
Check the external voltage source (Ui) is 5-27V
DC with a voltage meter
Check if the connection is correct: the 5-27V DC
should be connected to the collector connection
(pin 28+ or pin 30+) and the signal wire (S) to
the emitter connection (pin 29- or 31-)
Please contact technical support.
The consumption LED
is not flashing.
The pulse cable is not connected.
The load on the line is very low.
Connect the pulse cable.
Check the Ohm meter readings
No data received by the
M-Bus communication
port.
The ID is not correct.
The communication distance
is too long.
Too many meters connected.
The M-Bus terminals are not
connected correctly.
Check the Meter ID by looking for the A in the
display. The number in front of the A, for
example 15A gives the actual address the
meter uses. The default for this meter is 0A.
Make the distance between the meter and the
reading device shorter. Make sure it is no more
than ≤1000m
The number of M bus devices connected to the
meter should not exceed 64.
Make sure that the M-bus wires are connected
to terminals 34and 35. If the checks above
don’t solve the problem, please contact
technical support for a meter replacement.
