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.
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.

Note-2
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 Vsupply input.
External fuse must be on (+) line connection in Zsupply input.
