Instruction
1
Pass the mandatory verification of the meter. It carries out the inspection services, they also sealed the counters of electrical energy. It is recommended to connect single-phase electric meter to carry out the instructions, which is attached to the device. The regulation contains a detailed description of its technical characteristics and other parameters.
2
Install single-phase electric meter, using the mounting screws. Place with the outer side wall insulator that looks like a funnel. Inside it has the form of a sleeve. As insulators can be used lead or PVC tube. Connection diagrams single-phase meter include insulated wiring from an external point input to the counter. Do isolation single-wire or conducting cable with a solid cross-section. Copper wire should be with a cross section of at least 2.4 mm2 or aluminum wire size of 4 mm2 or more.
3
Do the wiring, leaving the free ends of the wires (at least 12 inches). Connect the wires to the terminals of single-phase electricity meter using the marking (phase wire - 1 on the left terminal, ground wire to the 3rd terminal from the left, the load wire - 2-I and 4-I). Insulation or sheath wire with zero voltage to the meter is recommended to make a color different from the rest of the wires (length approximately 10 cm).
4
Produce the passage of electric current from the start current of the windings to their end. Terminal cover phase meter, includes 4 power contact. Two are for single-phase current, and the other two to supply it to the wiring. If you use transformers, it is necessary to consider the polarity of the transformer voltage and current.
