DMM-5T-3 User manual
»
Note that the value of current transformer is higher than the maximum current drawn from the system.
»
It is advisible that the class of the current transformer (it can be wri� en class, klas, cl, kl) is 0.5.
»
To avoid the complexity when connec� ng the current transformer output terminal use diff erent colour
cables or give cable numbers.
»
Please spread the cables which are connected to current transformer output terminal from remote high
voltage lines.
»
Please fi x current transformers to bara, cable or rail to avoid ra� ling.
»
Please use the device properly according to our direc� ons.
»
Please protect LCD screen from sun light.
»
Please take 5 cm space behind the device a� er the device installa� on.
»
The meter should be fi xed to the board using the included latches.
»
Please not use device in the damp board.
»
Voltage inputs and power supply of the meter should be protected with 0.5÷1 A slow-blow fuses.
»
There should be no electricity in the connec� on cables when assembling device.
»
RS-485 communica� on and pulse inputs should be connected via shielded and/or twisted pair cables.
These cables should be routed as far as possible from power lines.
»
Assembling and electrical connec� ons must be done by technical staff according to instruc� on manuel.
»
The feed cables should be suitable for IEC 60227 or IEC 60245 requirements.
Turn off energy of the device and disconnect from connections. Clean the device body by using slightly moist
or dry cloth. Do not use conductor or other chemical as a cleaning agent matter which is harmful to device.
Make connections after the cleaning of device and give energy to device and make sure that device works
properly.
Energy analyzer measures load or voltage, current, cosφ, active power, reactive power , minimum and maxi-
mum values of the load and also measures demands. It records the events. This analyzer measures current
harmonics and voltage harmonics up to 55. harmonics.
Please read the warnings before powering the device. Make connections of the device according to the
connection scheme. When the device is first powered up figure-4 displayed on the screen. Firstly enter the
current transformer ratio from the settings menu and if the voltage transformer medium voltage is being
measured), enter the voltage transformer ratios.
