3.3. Principle of operation
Area of application The DT1300 xx xx xx Intrinsically Safe Isolator / Power
Supplies provide signal transmission between transmitters
operate in zone 0, zone 1 potentially explosive area and
the signal processing unit operates in the safe area.
The instruments isolate the input, the output and the power
supply.
The intrinsically safe input signal may be:
0-20 mA, 4-20 mA, 0-10 V,
the output signal also may be:
0-20 mA, 4-20 mA, 0-10 V.
The isolators available with two different transmitter
supplies (17 VDC or 18 VDC nominally). The safety data
these two types differ considerably from each other, thus
they can be flexibly matched to the various transmitters.

Operating principle
The instruments are powered from a 19-29 VDC supply
through a dual output high frequency DC-DC converter.
One output supplies power for the input (Ex) side and
supplies power for the transmitter connected to the input,
the other supplies power for the output (safe) side. The DC
isolation and intrinsically-safe segregation are provided by
high isolation optocoupler. The DC signal transmission
based on a high precision pulse modulation-demodulation
principle.
Power supply The instrument works from a 19-29 VDC supply voltage.
The power consumption is 2.2 W.
3.4. Adjustment
The DT1300 xx xx xx doesn’t need any adjustment.
After connected to the power supply it is ready to work.
3.5. Indicator
The following figure shows the indicator on the instruments
front:
1. “power” green indicator, indicates the power on state of
the instrument.

3.6. Storage and transport
This instrument should be stored and transport in places
whose climatic conditions are in accordance with chapter
8.1. Technical specification, as described under the title:
Environmental conditions.
The packaging of DT1300 xx xx xx 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 instructions
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 8.1. 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 5 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.

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 DT1300 xx xx xx and other
instrument (e.g. transmitter). 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 mm2.
You may use either solid conductor or flexible conductor.
In case of using flexible conductor use crimped wire end.
Take note of the corresponding installation regulations for
Ex applications (MSZ EN 60079-25). 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
fequency interference signals) this can be achieved by use
separate potential equalization or by use of a blocking
capacitor (e.g. ceramic capacitor 1 nF, 1500 V) or. The low
frequency potential equalization currents are thus
suppressed, but the protective effect against high
frequency interference signals remains.

6. Fault rectification
6.1. Fault finding
The fault finding must be carried out by trained and
authorized personnel only!
Use only an Ex certificated 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 input signal.
If the input signal is OK, the instrument is defective.
•There is no input signal →check the transmitter supply.
If the transmitter supply is OK, the transmitter is defective.
When the result of fault finding is that the DT1300 xx xx xx
is defective call the manufacturer service department.
6.2. Repairing

Dismounting from the
rail
The dismounting procedure needs a screwdriver for slotted
screws.
Pull out all the terminals:
1. Put the screwdriver into the slot between the terminal
and the housing (figure step 1.).
2. Lift (lower terminals) or push down (upper terminal) the
screwdriver handle as far as the terminals will be free
(figure step 2.).
Dismount the instrument:
3. Put the screwdriver end into the fixing assembly’s hole
(figure step 3.).
4. Lift the screwdriver handle until it possible to open the
fixing assembly (figure step 4.).
5. Keeping the screwdriver in this position lift the
instrument bottom from the bottom edge of the rail (figure
step 5.).

6.Lift the whole instrument (you may put out the
screwdriver) (figure step 6.), as far as the instrument will be
free.
(If necessary - after lose screws of terminals - pull the wire
out from connector block, then put in connector blocks
back to onto the instrument. There are coding pins on
connector blocks which prevent interchange of connector
blocks.)
7.2. Disposal
According with the concerning EU directive, the
manufacturer undertakes the disposal of the instrument
that are manufactured by it and intended to be destroyed.
