The unit is equipped with a liquid-crystal display. When the unit is switched off, the LCD shows "OFF", when the unit is switched on it shows the INV output voltage and output current. While the INV starts up and output contactor K7 is still switched off, "READY" is signalled.

In the event of a fault, the 1st display row shows "FAULT" and the 2nd display row shows the type of fault.

The INV voltage and current values are displayed with three decimals before and one decimal after the decimal point. The display accuracy corresponds to class 1 with respect to the rated output value of the unit.

Remote signalling is carried out by means of potential-free contacts via a Combicon connector on the front of the unit.

Assignment of the signal terminals:

INV fault:

In the event of a signal, X10.2 – X10.3 or X3.2 – X3.3 close. No fault: X10.2 – X10.1 or X3.2 – X3.1.

When the INV is disconnected from the power supply (no DC supply), a fault is signalled!

The remote signals are designed for safe isolation. The minimum load should not be below 12 V and 0.1 A.
