Safety instructions
Information for Your Own Safety
This manual does not contain all of the safety measures for operation of the equipment (module, device), because special operating
conditions, and local code requirements or regulations may necessitate further measures. However, it does contain information which must
be adhered to in the interests of your own personal safety and to avoid material damages. This information is highlighted by a warning
triangle is represented as follows, depending on the degree of potential danger.
WARNING
Means that failure to observe the instruction can result in death, serious injury or considerable material damage.
CAUTION
Means hazard of electric shock and failure to take the necessary safety precautions will result in death, serious injury or
considerable material damage.
Proper handling
The prerequisites for perfect, reliable operation of the product are proper transport, proper storage, installation and assembly, as well as
proper operation and maintenance. When operating electrical equipment, certain parts of this equipment automatically carry dangerous
voltages. Improper handling can therefore result in serious injury or material damage.
• Use only insulated tools.
• Do not connect while circuit is live (hot).
• Place the meter only in dry surroundings.
• Do not mount the meter in an explosive area or exposed to dust, mildew and insects.
• Make sure the used wires are suitable for the maximum current of this meter.
• Make sure the AC wires are connected correctly before activating the current/voltage to the meter.
• Do not touch the meter connecting clamps directly with your bare hands, with metal, blank wire or other material as you will have the
chance of an electricity shock and a possible chance for health damage.
• Make sure the protection cover is replaced after installation.
• Installation, maintenance and repair should only be carried out by qualified personnel.
• Never break the seals and open the front cover as this might influence the functionality of the meter, and will void any warranty.
• Do not drop, or allow physical impact to the meter as there are high precision components inside that may break or render the meter
measures inaccurate.

CAUTION
• Turn off and lock out all power supplying the energy meter and
the equipment to which it is installed before working on it.
• Always use a properly rated voltage sensing device to confirm that
power is off.
WARNING
• Installation should be performed by qualified personnel familiar
with applicable codes and regulations.
• Use isolated tools to install the meter.
• We recommend that the connecting wire which is used to connect
the meter to outside circuit should be sized according to local
codes and regulations for the ampacity 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 be near the meter so that it is convenient for the operator.
The switch or circuit-breaker should comply with the
specifications of the building 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 in a good ventilated and dry place.
• The meter has to be installed in a protection box when placed in
dangerous or dusty environments.
• 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 in accordance with the
underneath connection diagram.

Working indication
On the EFMN-3DK's front panel, there are three power indicating
LED which have different color from each other. The yellow LED
represent L1 phase; the green LED represent L2 phase; the red
LED represent L3 phase. When any phases work normally, the LED
representation will burn. When any phases have failure or no power,
the LED will turn off.
Consumption indication
There is a PULSE LED which is used as indicating power
consumption in the front panel of EFMN-3DK When consumption
happens, the LED will flash. The more quickly LED flash, the more
consumption there is. For this LED, the flash rate is 400 impulses
per kWh (2.5Wh/imp).
Reverse indication
There is REV. LED on EFMN-3DK front plate. When meter load
current flow is reverse, the LED lighten.
Reading the meter
The EFMN-3DK energy meter is equipped with a 5+2 LCD display
which is used as recording consumption and can't be reset to zero.
The number system is based on units of 10 and the unit is kWh.
