5.7.6 Connection of a DC1 data collector from
Delta
You can use the DC1 data collector for, among other things:
●
Commissioning the inverter (see "6. Planning the Commis-
sioning", page 54 and "8. Commissioning", page 86)
● Updating the firmware
●
Connecting to the MyDeltaSolar Cloud or another monitor-
ing system
The inverter can be connected to the DC1 via RS485, Sub-1G or
Wi-Fi.
Connection via RS485
Observe the general instructions in section "5.7.5 Connection of
a data logger via RS485", page 49.
The DC1 does not have an integrated RS485 termination resis-
tor. For this reason, refer to the information in Fig. 5.29.
