DKM-407 DIN RAIL TYPE NETWORK

ANALYZER

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.

Failure to follow below

instructions will result in

death or serious injury

 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.

SAFETY NOTICE

INSTALLATION

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.
