Datakom DKM-407, Manual

Page: 1 / 4

The DKM-407 is a DIN rail mounted precision
unit allowing measurement and monitoring of
AC parameters of a distribution panel.
The unit is supplied between L1 and Neutral
terminals. Thanks to the supply range of 85-
305V, it is not affected by voltage fluctuations
and is capable of operating in any network.
The unit features an 32-bit ARM core
microcontroller. With a sampling rate of
4096s/s it reaches 0.5% precision.
The isolated RS-485 Modbus RTU port is not
affected by ground potential differences.
Program parameters may be uploaded from
PC.

Electrical equipment should be installed
only by qualified specialist. No responsibility
is assured by the manufacturer or any of its
subsidiaries for any consequences resulting
from the non-compliance to these
instructions.

Check the unit for cracks and damages due
to transportation. Do not install damaged
equipment.

Do not open the unit. There is no
serviceable parts inside.

Fuses of fast type (FF) with a maximum
rating of 6A must be connected to phase
voltage inputs, in close proximity of the unit.

Disconnect all power before working on
equipment.

When the unit is connected to the network
do not touch terminals.

Short circuit terminals of unused current
transformers.

Any electrical parameter applied to the
device must be in the range specified in the
user manual.

Verify correct terminal connections before
applying power.
Before installation:

Read the user manual carefully, determine
the correct connection diagram.

Install the unit to the DIN rail.

Make electrical connections with plugs
removed from sockets, then place plugs to
their sockets.

Note that the power supply and measuring
circuits use common neutral.
Below conditions may damage the device:

Incorrect connections.

Incorrect power supply voltage.

Voltage at measuring terminals beyond
specified range.

Current at measuring terminals beyond
specified range.

Connecting or removing data terminals
when the unit is powered-up.

Overload or short circuit at relay outputs

Voltage applied to digital inputs over
specified range.

High voltage applied to communication port.
Below conditions may cause abnormal
operation:

Power supply voltage below minimum
acceptable level.

Power supply frequency out of limits

Phase order of voltage inputs not correct.

Current transformers not matching related
phases.

Current transformer polarity incorrect.
