The setting values are altered by removing the plastic caps by means of a screwdriver.

Important: If the "reverse" power trimmer is turned anticlockwise as far as it will go, the return power relay responds because this is the test setting.

The luminous diode signalizes the existing reverse power virtually without any delay.

If the return watt relay responds at "forwards power" then either the "reverse power" response value has to be set higher for the "k" current transformer connection is to be changed over the "l" current transformer connection.

When installing the reverse power relay it is important that the "measuring voltage" supply voltage originates from the same phase as that to which the current transducer is connected.
