2, the instrument wiring

Refer to the wiring diagram on the meter housing.

3, wiring on the attention

(1) Input signal line To avoid the interference of noise, please try to stay away from the instrument power line, power line load line and other wiring.

(2) The wiring of the instrument power cord should be avoided as far as possible from the power supply noise interference, such as near the noise source, and the instrument may be affected by noise interference, please use the interference filter.

★ If the filter can not get good results, please refer to the filter frequency, characteristics, etc. to be selected.

★ To reduce the interference of the meter power supply wiring, shorten the twist pitch and make the twist pitch shorter.

★ Filter must be installed in a good grounded instrument panel and other places, and the filter output side and the instrument power supply terminals with the shortest.

Note: The effect of the filter can not be obtained by lengthening the distance between the output side and the power supply terminals of the meter.

★ If the fuse is installed on the wiring of the noise filter output side, the filter effect will not be obtained.

(3) For wiring, use a wire that conforms to the Electric Appliance Management Law (ground wire with a nominal area of ​​1.25 to 2.0 m 2 for the instrument ground).

(4), the power input requires 2 to 3 seconds of contact output preparation time, such as the external connection circuit signal, use the delay relay is appropriate.

Eight, selection table
