-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 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 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.
-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.

more quickly LED flash, the more consumption there is.
Reading the meter
The PRO-1TE series energy meter is equipped with a 5+1 register. five integers are
marked with black color and one decimal is marked with red. The PRO-1TE LCD series
energy meter is equipped with 5+2 LCD display which is used as recording
consumption and can’t be reset to zero. The reading accuracy is 1/100 kWh.
Pulse output
The PRO-1TE Series DIN rail energy meter is equipped with a pulse output which is fully
separated from the inside circuit. That generates pulses in proportion to the measured
energy for accuracy testing. The pulse output is a polarity dependant, passive
transistor output requiring an external voltage source for correct operation. For this
external voltage source, the voltage (Ui) should be 5-27V DC, and the maximum input
current (Imax) is 27mA DC. To connect the impulse output, connect 5-27V DC to
connector 20 (anode), and the signal wire (S) to connector 21 (cathode).

Only when load is running, this
LED will flash.
If the operating power is too low,
the spacing interval of flashing
will take some more time, this is
why it seems like LED isn’t
burning.
Please contact your technical
supporter to replace this meter.
The register can’t
run.
Is there a power
supply inside the
meter ?
Is the operating
power too low ?
Maybe there is a
fault in the inside
circuit.
Check that the power supply
indicator is burning.
If the operating power is too low,
the spacing interval of the pulses
will take some more time, this is
why it seems like the meter won’t
count.
Please contact your technical
supporter to replace this meter.
No pulse output.
Is DC power supply
connected to the
