1-Before mounting the device in your
panel, make sure that the cut-out is of
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.
2.4InstallationFixingClamp

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
holes that located left and right sides of
the device and make the unit completely
immobile within the panel
2.5RemovingfromthePanel

1
Loosen the screws
1-Pull mounting clamps from left and
right fixing sockets.
2-Pull the unit through the front side of
the panel
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.

Make sure that the power supply voltage is same indicated on the instrument. Switch on the power supply
only after that all the electrical connection have been completed. 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 or fuse on the device. So a power supply switch and a fuse must be added
to the supply voltage input. Power supply switch and fuse must be put to a place where user can reach
easily. 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.
External fuse must be on (+) line connection in supply input.
