4.3.2 Connecting the
Inverter Manager
Do not connect during operation
Do not connect the I/O Box to the Inverter Manager
during operation. Errors might occur that cannot be
detected immediately.
• Disconnect the Inverter Manager from voltage
sources.
• Connect the I/O Box with the Inverter Manager.
• Reconnect the Inverter Manager to the voltage
supply.

4.3.3 Connecting the Signal Source

Connection of a Signal Source with
Potential-Free Relay Contact
Dry Contact:
closed: DI0 = on
open: DI0 = off
Connection of a Signal Source (10 V to 30 V)
with Digital Output Signals
10 V to 30 V
U U
Wet Contact:
0 V to 3 V = off
10 V to 30 V = on
4.3.4 Connecting the I/O Box to the
Voltage Supply
Connect the 12 Vdc to 36 Vdc connection line with the
terminal for the voltage supply. Connect the grounding of
the connection line to the "V" terminal and connect the
grounding pin (GND) if grounding is present.

Assignment
V- / V+ Voltage supply 24 Vdc
(12 Vdc to 36 Vdc)
Diameter of the leads
For safety reasons, the leads for the electricity supply
must have a diameter of at least 2 mm².
