single phase mechanical energy meter

1.the meter should be mounted either on a wall or on a panel, both of which should be free from shake. It's recommended that the meter should be mounted 1.7m above the ground. While being mounted, the inclination of the meter from it's vertical position should be guaranteed not to exceed 10. In places where there is dirt of posibility of damaging the function of the mechanism the meter should be put in a protective box.2.Before connecting the meter into the circuit make sure that the voltage of the circuit is the rated value and the current of the circuit does not exceed the rated maximun value. Connecting should be done as shown in the connection diagram.
