3.3. Principle of operation
Area of application
The DT2500 IS Power Supply provide IS power for devices operate in
zone 1 potentially explosive area.
The power supplies are available in seven different output voltage and
current variations (see table on the previous page). A front panel
potentiometer makes possible to adjusting the output voltages,
therefore any voltage of range the 5,8 - 24 V can be ensured. The
LED indicators show information from output voltages, and the fault
conditions.
The EEx classification of the power supplies is: II (2)G [Ex ib Gb] IIC
or II (2)G [Ex ib Gb] IIB.
You can see the detailed information on chapter 10.1. Technical
specification.
Operating principle
The connected line voltage through voltage transformers, through the
rectification and filtration come to the input of control circuit. The
control circuit generates - depending of the type – the output voltage.
This voltage goes to two independent current limiting units. These
currents limits units are ensure the Io short-current. In case of
overload, the red LED light. After the currents limit units the output
voltages come in the outputs terminals. The Uo output voltage is
limited by zener diodes.
If the supply voltage higher than 250 V safety value, the mains fuse
blow out. The thermal fuse protects the power transformer from
overheating.
Power supply 200-250 VAC; 50/60 Hz
10 VA/7 W
3.4. Adjustment
After the device connected to the power supply ready for operation.
You can find detailed information for settings on 7. Settings chapter.

3.5. LED indicators
The following figure shows the front panel LED indicators:
1, "overload" indicator, light red, indicates the unit is overloaded.
2, "power" indicator, light green, indicates the output voltage is
present.
3, P1 potentiometer to adjust the output voltage.
3.6. Storage and transport
This instrument should be stored and transport in places whose
climatic conditions are in accordance with chapter 10.1. Technical
specification as described under the title: Ambient conditions.
The packaging of DT2500 consist of environment-friendly, recyclable
cardboard is used to protect the instrument against the impacts of
normal stresses occurring during transportation. The corragulated
cardboard box is made from environment-friendly, recyclable paper.
The inner protective material is polyfoam and nylon, which should be
disposed of via specialized recycling companies.

4. Mounting
4.1. General instruction
The instrument should be installing in the safe area in a cabinet with
sufficient IP protection, where the operating conditions are in
accordance with chapter 10.1. Technical specification, as described
under the title: Operating conditions.
Mounting position
The instruments are designed in housing for mounting on TS-35 rail.
The instruments should be mounted in vertical position (horizontal rail
position).
There are spacers both sides of the housing to keep 15 mm distance
between the instruments for the sufficient cooling.
Horizontal mounting may cause overheating and damage of the
instrument!

4.3. Mounting procedure
The following figure shows the mounting procedures (fixing on the
rail):
Mounting on the rail
The mounting doesn’t need any tool.
1. Tilt the instrument according to the figure; put the instrument’s
mounting hole onto the upper edge of the rail (figure step 1.).
2. Push the instrument’s bottom onto the bottom edge of the rail
(figure step 2.); you will hear the fixing assembly closing.
3. Check the hold of the fixing by moving the instrument firmly.
Leave at least 15 to 15 mm air space on both sides of the power
supply.

5. Connecting
5.1. Preparing the connection
Select and prepare
connection cable
Always observe the following safety instructions:
•When you are going to install instruments in hazardous area or
install instruments which are connecting to instruments are working in
hazardous area you should take note of the appropriate regulations,
conformity and type approval certificates of the DT2500 and other
instrument. The connection must be carried out by trained and
authorized personnel only!
•Connect only in the complete absence of supply voltage
•Use only a screwdriver with appropriate head
Take note the suitability of the connecting cable
(Wire cross-section, insulation, etc.).
The wire cross-section should be 0.25-1.5 mm.
You may use either solid conductor or flexible conductor.
In case of using flexible conductor use crimped wire end.
The compensating current can not flow on the cable shield!
The cable shield should only be grounded on one side, preferably on
the instrument room. Make sure that, the shield should be
continuous, between the source (DT2500) and the connected device
Take note of the corresponding installation regulations for
Ex applications. In particular, make sure that no potential equalization
currents flow over the cable screen. Ground only one side the cable
screen (it’s recommended the transmitter side).
If necessary of grounding on both sides (for suppress very high level,
high frequency interference signals) this can be achieved by use of a
blocking capacitor (e.g. ceramic capacitor 1 nF, 1500 V) or separate
potential equalization. The low frequency potential equalization
currents are thus suppressed, but the protective effect against high
frequency interference signals remains.
The DT2500 device has a very effective interference protection,
therefore grounding both sides of the cable is usually not necessary.
if interference emitting devices operating beside the DT2500 device
(eg inverter) may require the application of the above. Important rule
that the signal cables, control and power cables pass it separately.

If the factory setting is good, you do not need configurable anything.
If you want configurable your device, before the normal use you need
follow the 7. Settingschapter.
7. Settings
7.1. The general settings
Necessary devices The setup requires the following devices:
•Voltmeter, measure the output voltage
•Screwdriver, to adjust the output voltage
Setting process The output voltage is set to the nominal voltage
(6, 8, 10, 12, 15, 18 or 24 V) by manufacturer. If you want smaller
voltage as the nominal value you can adjust the voltage with
P1 potentiometer. The adjusting you should only with free output
terminals.
1. Turn off the device (Turn off the power)
2. Disconnect the load from output terminals
3. Connect the voltmeter to the outputs terminals
4. Turn on the device (Turn on the power)
5. Adjust the output voltage with P1 potentiometer. The adjusted
voltage deviation is 1 % from the load voltage value
6. Turn off the device (Turn off the power)
7. Disconnect the voltmeter from output terminals
8. Connect the load to the outputs terminals
9. Turn on the device (Turn on the power)
The inductance of the cable and capacitance of the cable shall be
deducted from the security data (Lo, Co).

8. Fault rectification
8.1. Fault finding
The fault finding must be carried out by trained and authorized
personnel only! Use only an Ex proofed measuring instrument when
measuring on the input (Ex) side.
•The green indicator is dark →check the power supply.
If the supply voltage is OK, the instrument is defective.
•There is no output signal →check the power supply and overload
indicator.
If the supply voltage is OK, and the overload indicator is dark, the
instrument is defective.
When the result of fault finding is that the DT2500 is defective call the
manufacturer service department.
8.2. Repairing
There is no user repairable part inside the instrument.
In accordance with Chapter 2.1.: For safety and warranty reasons,
any internal work on the instrument must be carried out by
DATCON personnel.

Dismounting from the
rail
The dismounting procedure needs a screwdriver for slotted screws.
1. Before dismounting disconnect all wires.
2. Put the screwdriver end into the fixing assembly’s hole (figure step
1.).
3. Lift the screwdriver handle until it possible to open the fixing
assembly (figure step 2.).
4. Keeping the screwdriver in this position lift the instrument bottom
from the bottom edge of the rail (figure step 3.).
Lift the whole instrument (you may put out the screwdriver) (figure
step 4), the instrument will be free.
