The Selec MFM374 Electrical Panel Meters is a Multifunction Meters which can indicate voltage, current, power, power factor, frequency and energy in operation of equipment, machinery, systems or processes in a wide range of industrial applications. It consists of LED display 3 rows of 4 digits, 8 digits for energy. Comprises of Input type: 3ø-4, 3ø-3, 2ø-3, and1ø-2 wire, 5A max and a Programmable CT/PT primary and secondary. Supply Voltage: 85 to 270V AC/DC (50/60 Hz).

• To prevent the risk of electric shock, power supply to the equipment must be kept OFF while doing the wiring arrangement.
• Wiring shall be done strictly according to the terminal layout. Confirm that all connections are correct.
• Use lugged terminals.
• To reduce electromagnetic interference use of wires with adequate ratings and twists of the same in equal size shall be made with shortest connections.
• Layout of connecting cables shall be away from any internal EMI source.
• Cable used for connection to power source, must have a 2 2 0 cross section of 0.5mm to 2.5mm ( 20 to 14AWG ; 75 C (minimum)).Thesewires shall have current carrying capacity of 6A.
• Copper cable should be used ( Stranded or Single core cable ).
