2 - Points to take into consideration in the selection and connection of Current Transformer:
In order to prevent any mistake while connecting the output terminals of the current transformer,
use cables in different colors for each phase or designate a number for each cable.
Keep the cables connected to the output terminals of the current transformer away from the
high-voltage line.
In order to prevent any shake on the current transformer, fix it on the bus-bar, cable or rail.
Be sure that the current transformer value is higher than the maximum current drawn from the
system.
3 - Warnings:
Do not expose the LCD display directly to sunlight in order to avoid any harm on it.
Note that the temperature level on the panel to which the device is mounted is at the range of
operating temperature of the device (-20°C.....55°C)
There must be a space of 5cm behind the device after its installation.
Use the device according to the instructions specified by us.
Fix the device securely to the front-cover of the panel with the apparatus delivered together with the
device.
Place the switch or circuit breaker close to the device or in a location that is easily accessible for the
operator.
Be sure that the panel to which the device is mounted does not operate in a humid environment.
Place a switch or circuit breaker on the system during installation of the device.
Please note that the cables must not be energized during installation.
Flexible monitored and twisted cables must be used for the input and output lines which are not
connected to the mains.
The technical personnel according with the instructions specified in the user's manual must perform
installation of the device and electrical connections.
The feeder cables must be compatible with the requirements of IEC 60227 or IEC 60245
5 - General:
EM-07 Multimeter measures the load on the system and voltage, current, apparent power minimum and
maximum values, demands related to this load on the system.
4 - Maintenance of the Device:
De-energize and disconnect the device. Clean the body of the device with a dry or damp-dry cloth. Do not
use conductive or other chemical substances as a cleaning agent that can damage the device. After
cleaning the device, make its connections and check whether it is working by energizing it.
