3.Electrical Wirings
You must ensure that the device is correctly configured for your application.
Incorrect configurationcould result indamage to the process beingcontrolled,
and/or personal injury. It is your responsibility, as the installer, to ensure that
c
the configurationis correct.
Parameters ofthe device has factory defaultvalues. These parametersmust be
set accordingto thesystem’s needs.
Only qualified personnel and technicians should work on this equipment. This
equipment contains internal circuits with voltage dangerous to human life.
There issevere dangerfor human lifein thecase of unauthorizedintervention.
c
Be sure to use the rated power supply voltage to protect the unit against
damage andto preventfailure.
c
Keep thepower off until all ofthe wiring is completed sothat electric shockand
trouble withthe unitcan be prevented.
Electrical wiring of the device must be the same as ‘Electrical Wiring Diagram’
below toprevent damageto the processbeing controlledand personnel injury.

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.
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 accidentsas aresult of incorrectsupply voltage.
There is no power supplyswitch on the device. So a power supply switch must
be addedto the supplyvoltage input. In accordancewith the safetyregulations,
the power supply switch shall bring the identification of the relevant
instrument.Power supplyswitch shallbe easily accessibleby theuser.
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 ofpower switchmust be signedfor preventingthe wrong connection.

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 forrepair.
