The DKM-409 is a precision instrument
designed for displaying various AC
parameters in 3-phase distribution panels.
The unit has 3 x 4-20mA analog outputs. Any
measurement can be output as analog value.
The unit has 4 digital inputs and 2 relay
outputs with programmable functionality,
selected from a list.
Thanks to its isolated RS-485 Modbus RTU
communication port, the device is free from
ground potential difference issues and
measured parameters are safely transferred
to automation systems.
* 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 the power
supply and 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.
* Do not try to clean the device with solvent
or the like. Only clean with a dry cloth.
* Verify correct terminal connections before
applying power.
* Only for front panel mounting.
Before installation:
Read the user manual carefully, determine
the correct connection diagram.
Remove all connectors and mounting
brackets from the unit, then pass the unit
through the mounting opening.
Put mounting brackets and tighten. Do not
tighten too much, this can brake the
enclosure.
Make electrical connections with plugs
removed from sockets, then place plugs to
their sockets.
Note that the power supply terminal is
separated from measurement terminals.
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 specified
limits
Phase order of voltage inputs not correct.
Current transformers not matching related
phases.
Current transformer polarity incorrect.
