When the CT is connected to earth, a leakage current from 0 to 1.8mA max is generated, whose value depends on the input
impedance values of the instrument, on the type of connection and on the line voltage measured by the instrument.

Output connections
Open collector outputs: The load resistance (Rc) must be
designed so that the closed contact current is lower than
100mA; the VDC voltage must be lower than or equal to 30V.
VDC: external power supply voltage. Out: positive output con-
tact (open collector transistor). GND: ground output contact
(open collector transistor).
Relay out.
