BÖLÜM 1 GENERAL INFORMATION
1.1 Symbols
Caution:
Wherever used, this symbol indicates that there is important
information that must be taken into consideration.
Danger of Electric Shock:
This symbol indicates that there is dangerous voltage or current.
1.2 General Warnings
• Do not work under live supply conditions. Before installation, turn off the power of the
panel or any other related equipment.
• Installation, operation and commissioning (putting into service) of KLEA must be
performed by qualified personnel.
• The device must be put into service only after all connections are made.
• KLEA is connected to current transformer(s). Before disconnecting current transformer
leads, be sure that they are short circuited elsewhere or connected to a parallel load
which has sufficie tly low impedance. Otherwise dangerously high voltages will be
induced at the current transformer leads. Same phenomena also apply for putting into service.
• Keep and store away from moisture, dust, vibration and wet environment.
• For cleaning, remove the dust with a dry cloth. Do not use abrasives, solvents or alcohol.
• There are no user serviceable parts inside. Maintenance and calibration can only be
carried out at manufacturer’s end.
• It is recommend to connect circuit breakers or automatic fuses between voltage inputs
of Klea and the network.
1.3 Receipt Control and Contents of Delivery
When you receive the package, please be sure that,
• packing is in good condition,
• product has not been damaged during transportation,
• product name and reference (order) number conforms to your order.

1.4 KLEA Energy Analyzer
KLEA is a multi functional energy analyzer. KLEA,
Measures/calculates:
• Current, voltage and frequency
• Active, reactive and apparent power
• Current and voltage harmonics up to 51. harmonic
•THDV, THDI
• Power factor, cosØ for each phase.
KLEA has “ Import Active” , “ Export Active” , “Reactive R1” , “Reactive R2” , “Reactive R3” ,
“Reactive R4” meters. These meters record “1st tariff ”, “T1_1” , “T1_2” and “T1_3” energy
values.
• There is an isolated RS485 port in KLEA.
• KLEA’s energy/meter values can be assigned to digital outputs.
• It has 2 pieces of relay outputs.
SECTION 1 GENERAL INFORMATION

4Quadrant
Energy Analyzer 4Quadrant Energy Analyzer
Besides, KLEA has numerous features such as;
• Setting alarms for various measurement parameters,
• Monitoring official ene gy meters by means of assigning initial values for Klea tariff
meters,
• Compatibility for 3 phase/3 wire, 3 phase/4wire or aron connected systems,
• Avoiding unauthorized control by a 4-digit password.
KLEA Energy Analyzer has,
•2 programmable alarm relay outputs, 2 digital outputs (totally 7 pieces in optional
digital IO model), 2 digital input (totally 7 pieces in optional digital IO model), 1 piece
of RS-485 communication port, 2/4 analog outputs (optional), battery supported real-
time clock and memory.
•There are 6 keys and 160x240 graphical LCD on the front panel. By means of them,
device settings and monitoring of measurement values can eaClear y be accomplished.
1.5 KleaCom Software
Operator can remowirey reach a Klea device via KleaCom software.
KleaCom software can communicate with only one Klea at the same time; operator can
reach other Klea devices on the same network by changing the slave ID.
All measured/calculated parameters can be monitored with KleaCom. All settings of Klea
can be changed/read via KleaCom software.
History (archive) data of Klea can be downloaded using KleaCom and this data can be
listed in an MS Excel or WordPad file (selectable).
KleaCom software is included in the CD-ROM received with Klea package.
Latest version of KleaCom software can be downloaded from www.klemsan.com.tr.

1.7 Four-Quadrant Represantation
The angle(Ø) between voltage and current provides us information about the direction of
energy fl w. A positive sign for active/reactive power indicates that active/reactive power
is consumed. And also a negative sign for active/reactive power indicates that active/
reactive power is generated.

NOTE: If the signs of active and reactive power are examined, it can be defined the
quadrant that Klea measures.
E.g.;
P= +10kWh,Q= +5kVAr => Quadrant-1
P= -10kWh, Q= +5VAr => Quadrant-2
P= -10kWh, Q= -5kWh => Quadrant-3
P= +10kWh,Q=-5kWh => Quadrant-4

BÖLÜM 2 INSTALLATION
This section provides the information about installation, mounting, cable routing and
connections of Klea.
2.1 Preparing for Installation
The purchased KLEA may not include all hardware options referred in this document.
This situation does not constitute an impediment to the electrical installation.
Assembly and related connections of KLEA, must be implemented by
authorized persons in accordance with the instructions of user manual.
The device must not be put into service if the operator is not sure that
all connections are correctly accomplished.
2.2 Mounting
KLEA is placed vertically into the gap located in the panel.
Fig. 2-1 Mounting KLEA into the Panel
After the KLEA is placed into the panel, fixing brackets should be installed on Klea and
Klea should be fixed to the panel wall with the screws.

There are 2.5mm2 and 1.5mm2 screwed female terminal blocks connected to fixed male
terminal blocks on KLEA. Remove female terminal blocks and loosen their screws.
Fig. 2-3 Loosening of Terminal Block Screws
Before wiring up voltage and current ends to KLEA, you must be sure that
the power is cut.

Energy Analyzer 4Quadrant Energy Analyzer
KLEA is connected to current transformer(s). Before disconnecting
current transformer leads, be sure that they are short circuited elsewhere
or connected to a parallel load which has sufficie tly low impedance.
Otherwise dangerously high voltages will be induced at the current
transformer leads. Same phenomena also apply for putting into service.
The cable is placed into the related opening.
Fig. 2-4 Inserting Cable into the Terminal Block
After the cable is placed, the screws are tightened and the cable is fixed.
Fig. 2-5 Fixing the Cable to the Terminal Block
The Terminal Block is inserted into its seat located on KLEA.

If KLEA is used together with current transformers, please pay attention to the following warning.
Threshold values for proper operation of current transformers dier according to the
type and size of the transformers being used.
Before applying the points mentioned in the following warning, please check that
the measured current value is larger than the current threshold value of the current
transformer (Refer to manual or datasheet of the current transformer).
For both of the warnings below, there must be a current in the system which is higher
than the threshold value of the current transformer (if any).
If KLEA is placed in a panel which consumes power;
The signs on Measure/Instantaneous/Active Power screen, should be positive, as the
phases consume power.
If there is a negative sign, turn off the device, cut off the panel power and then cross
connect K and L ends of the current inputs belonging to the related phase(s). After that,
check that all values are positive on Measure => Instantaneous => Active Power screen.
If KLEA is placed in a panel which generates power;
The signs on Measure/Instantaneous/Active Power screen, should be negative, as the
phases generate power.
If there is a positive sign, turn off the device, cut off the panel power and then cross
connect K and L ends of the current inputs belonging to the related phase(s). After that,
check that all values are negative on Measure => Instantaneous => Active Power screen.
