1-Before mounting the device in your
panel, make sure that the cut-out is the
right size.
2-Insert the device through the cut-out.
If the mounting clamps are on the unit,
put out them before inserting the unit to
the panel.
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.

2-Pull the unit through the front side of
the panel
The unit is designed for panel
mounting.
1-Insert the unit in the panel cut-out
from the front side.
2- Insert the mounting clamps to the
fixing sockets that located left and
right sides of device and make the unit
completely immobile within 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

Supply voltage range must be determined in order. Device is produced
different for low and high voltage. 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 or fuse on the device. So the user must put
power supply switch and a fuse 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 and fuse must
be put to a place where user can reach easily.
c
Power supply switch must be two poled for seperating phase and neutral.
On/Off condition of power supply switch is very important in electrical
connection. On/Off condition of power supply switch must be signed for
preventing the wrong connection.
External fuse must be on phase connection in supply input.V
c
c
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.
