KLEA 5 & POWYS 6

1.1 Features and Models
KLEA 5 and POWYS 6 series devices can be used to measure electrical parameters like current, voltage,
frequency, harmonic, etc. in 3-phase systems. Devices have the following features optionally.
• RS485 (Modbus RTU) and Ethernet (Modbus TCP) Communication Interfaces
• Gateway Function
• Energy Meters
• 3 Tariffs
• Ability to store minimum, maximum and demand values
• Run hour, on hour and power interruption counters
• Digital Input/Output
• Alarm Relay Output
• Indication for phase loss and phase sequence at current and voltage inputs
• THDV, THDI
• Up to 31 current and voltage odd harmonics

1.2 Correct Usage and Conditions For Safety
• Installation and wiring must be performed by authorized technicians in accordance with the instructions
in the user manual. Do NOT commission the device before proper wiring.
• Make sure the device is de-energized before connecting to the mains.
• Short-circuit the k-l terminals of the current transformer in another location before disconnecting the
current transformers. Failing to do so will cause dangerously high voltages in the secondary terminals of
the current transformers.
• Use a dry cloth to clean the device. Do NOT use alcohol, thinner, or any abrasive materials.
• Make sure all wiring is properly made before commissioning the device.
• Do NOT open the device. There are no serviceable parts by the user.
• Keep the device away from humidity, water, vibrations, and dust.
• It is advisable to connect a circuit breaker or an automatic fuse between the current input of the device
and the mains (2 amps).

1.3 Front Panel
•  It is used to show the screen where
settings are not allowed.
•  Indicates the communication
status. The down arrow means that the
query is transmitted to the device, and
the up arrow means that data is received
from the device.
•  It shows the current and
voltages connected to the device. It
represents the 1st Phase, 2nd Phase, and
3rd Phase, respectively.
•  When the digital outputs are
active, the relevant icon is active.
•  Indicates that the device is in an
error state.
• Only exclamation  Current direction
reversed.
• Only triangular frame  Phase sequence
error
• Exclamation + Frame  Pulse Error
•  It is active when the device is in an alarm state. Alarm assignments can be made to the following
parameters.
• Voltage
• Current
• Frequency
• Active Power
• Reactive Power
• Apparent Power
• Power Factor
•  Indicates the active relay
