6. Insert the plug into the terminals.
7. Ensure that the supply voltage cable is securely positioned.
Connecting the Device at Installation Location 2
1. Strip off the conductor insulation of the cable by 8 mm.
2. If you are using bootlace ferrules, crimp them.
3. Connect the insulated conductors to the connecting terminal plate -X420 (see Section 6.3.1 "Connecting
Conductors to the Spring-Cage Terminal", page 24). Observe the correct allocation and ensure that the insulation
is not clamped.
4. Insert the plug into the terminals.
5. Ensure that the supply voltage cable is securely positioned.
6.4 Connecting the Cables to the Network Switch and Router
6.4.1 Connecting the Network Cables to the Network Switch
Requirement:
☐ If you use more than one Communit in the PV system, the devices of all Communits must have different IP addresses
(see Section 7 "Commissioning the Communit", page 33).
Procedure:
• Connect the network cables to the network switch.
Terminal Signal
1 +24 VDC
2 0 VDC
Network settings prior to connection
The devices installed in the Communit are delivered with a standard configuration. This can therefore lead to IP
address conflicts when two or more Communits are used.
• If there is more than one Communit in the PV system, change the IP addresses of the devices in all Communits
except one before connecting to the network (see Section 7 "Commissioning the Communit", page 33).
