DRT-430A series User Manual
1.1 Foreword
Thank you for purchasing the B+G DRT-430 series DIN rail three phase four wire energy meters. With the
B+G product range we have provided a large scale of energy meters on the market suitable for 110V AC
to 400V AC (50 or 60Hz).
Although we produce the B+G DRT-430A series meter according to EN50470-3 and our strict quality
inspection, there might be possibilities that our product shows a fault or failure for which we do apologize.
Under normal conditions your product should give you years of benefit and pleasure. In case there is a
problem with the energy meter you should contact your dealer immediately. All energy meters are sealed
with a special seal. Once this seal is broken there is no possibility to claim for warranty. Therefore, NEVER
open meter by yourself or break the seal of the energy meter. The warranty time is 12 months after
installation, and only valid for construction faults.

1.5 Installation
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.
CAUTION
Turn off all the power 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
related procedures and regulations.
Use insulating tools to install the meter.
Fuse or thermal cut-off or single-pole circuit breaker can’t be fitted on
the supply line and not the neutral line.
The case is sealed, do not broken it

1.6 Operating
Consumption indication:
L1 indicator: it will become yellow when there is current in phase A
L2 indicator: it will become green when there is current in phase B
L3 indicator: it will become red when there is current in phase C
The other indicator is for pulse output. When consumption happens; the LED will flash and display red.
The more quickly LED flash, the more consumption there is.
Reading the meter:
The display digit of DRT-430A is 6+1. Six integers are marked with white color and one decimal is
marked with red.
Display function：It will display the total kWh consumed.
Pulse output
The DRT-430A 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.

Solution
No light for

indicator.
Is there current ?
Maybe there is a fault in the inside
circuit.
Only when there has current, this LED will
flash.

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
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 the connecting correct ?
Maybe there is a fault in the inside
circuit.
Check correct connecting:
connect 5-27V DC to connector 20 (anode),
and the signal wire (S) to connector 21
(cathode).
Please contact your technical supporter to
replace this meter.
