Datakom DKM-411 User manual

The DKM-411 is an advanced precision
metering device offering an 3.5” size,
320x240 pixel, color TFT, together with
unrivalled remote monitoring capabilities over
internet in a compact and low cost package.
The unit itself is a web page and can be
opened through any browser for remote
monitoring. The central monitoring feature
allows monitoring of thousands of analyzers
from one central PC.
User configurable screens where any
measured parameter set can be displayed,
transforms the unit to a custom designed
measurement panel.
* 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 dump cloth.
* Do not allow water to come in the unit.
* 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.
Make sure to use adequate fuses.
Do not subject the unit to water spill.
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
ports.
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.

INSTALLATION
SAFETY NOTICE
Failure to follow below
instructions will result in
death or serious injury

Although the unit is protected against
electromagnetic disturbances, excessive
disturbance can affect the operation,
measurement precision and data
communication quality.
Use adequate cable section, at least
0.75mm2 (AWG18).
For current transformer inputs, use at
least 1.5mm2section (AWG15) cable.
The current transformer cable length
should not exceed 1.5 meters. If longer
cable is used, increase the cable
section proportionally.
Current transformers must have 5A
output.
