During installation into a metal panel, care should be taken to avoid injury from
metal burrs which might be present. The equipment can loosen from vibration
and become dislodged if installation parts are not properly tightened. These
precautions for the safety of the person who does the panel mounting.
1-Before mounting the device in your
panel, make sure that the cut-out is of the
right size.
2-Check front panel gasket position
3-Insert the device through the cut-out. If
the mounting clamp are on the unit, put out
them before inserting the unit to the panel.

1-Loosen the screws.
2-Lift the locking tabs located on both the right and left
hand sides and pull the fixing clamp from the device
while holding the unit in place.
3-Pull the unit through the front side of the panel
Before starting to remove the unit from panel, power off the unit and the related
system.
Montage of the unit to a system must be done with it’s own fixing clamps. Do not
do the montage of the device with inappropriate fixing clamps. Be sure that
device will not fall while doing the montage.
The unit is designed for panel mounting.
1-Insert the unit in the panel cut-out from the front side.
2-Insert the mounting clamp from the rear side of the
unit and screw up the fixing screws until the unit
completely immobile within the panel

You must ensure that the device is correctly configured for your application.
Incorrect configuration could result in damage to the process being controlled,
and/or personal injury. It is your responsibility, as the installer, to ensure that
the configuration is correct.
Device parameters has factory default values. These parameters must be set
according to the system’s needs.
Only qualified personnel and technicians should work on this equipment. This
equipment contains internal circuits with voltage dangerous to human life.
There is severe danger for human life in the case of unauthorized intervention.
Be sure to use the rated power supply voltage to protect the unit against
damage and to prevent failure.
Keep the power off until all of the wiring is completed so that electric shock and
trouble with the unit can be prevented.

Supply voltage range must be determined in order. While installing the unit,
supply voltage range must be controlled and appropriate supply voltage must
be applied to the unit. Controlling prevents damages in unit and system and
possible accidents as a result of incorrect supply voltage.
There is no power supply switch on the device. So a power supply switch must
be added to the supply voltage input. In accordance with the safety regulations,
the power supply switch shall bring the identification of the relevant
instrument.Power supply switch shall be easily accessible by the user.
3.3 Connection of Device Supply Voltage Input

Power switch must be two poled for seperating phase and neutral. On/Off
condition of power switch is very important in electrical connection. On/Off
condition of power switch must be signed for preventing the wrong connection.

Make sure that the power supply voltage is the same indicated on the
instrument.
Switch on the power supply only after that all the electrical connections have
been completed.
The instrument is protected with an internal fuse (Please refer to Note1 for
information). In case of failure it is suggested to return the instrument to the
manufacturer for repair.

3.4.2 RTD Connection
Note 1 : In 3-wire system, use always cables of the same diameter (min ) Always use
wires of the same gauge and type whether a 2-wire or 3-wire system.
1mm²
Install a jumper between terminals 2 and 3 when using a 2-wire RTD.
If the distance is longer than 10 meters, use 3-wire system
Note 2 :
Note 3 :
3-wire Pt-100 connection
(with line compensation)
(Max. Line impedance is 10 )W
