Auxiliary power supply
Terminals 1-3
The auxiliary power supply can be the same as the network to control.
Insulation control
Terminals 5-11
The two terminals must be connected between the line under control and the earth measurement reference.
Terminal 5 must be connected to the neutral conductor of the single-phase or the three-phase line under con-
trol. If the three-phase network has three wires, the terminal must be connected to a phase. The maximum
voltage required between these terminals is 440V, and for this reason, it’s possible to use the insulation con-
troller on a single-phase line or on a three-phase line with 3 wires without neutral up to 440V and with 4 wires
with neutral up to 760V.
Relay output connections
Terminals 7-8-9
For remote signalling by relays with changeover contact max 5A 250V on resistive load.
Automatic or remote RESET connection
Terminal 12
By connecting terminal 12 to terminal 11 (ground), a manual RESET function is possible (using the pushbutton
on the front of the instrument). Without the connection at terminal 12, the instrument will function with
automatic RESET when the low insulation condition ceases. An external N.C. contact push-button can be
connected between the monitoring device and the ground.
