Communication Setup - Solplanet ASW30K-LT-G2 Guía De Instalación Rápida

2. Remove the plastic AC/COM cover from the inverter, pass the cable through the waterproof
connector on the AC/COM cover in the wall-mounting accessories package, and retain
the appropriate sealing ring according to the wire diameter, lock the cable terminals onto
the inverter-side wiring terminals respectively (L1/L2/L3/N/PE,M8/M5), install the AC insulation
sheets onto the wiring terminals (as shown in Step 4 of the figure below), then lock the
AC/COM cover with screws (M4x10), and finally tighten the waterproof connector.
(Torque M4:1.6Nm; M5:5Nm; M8:12Nm; M63:SW65,10Nm)
3. If required, you can connect a second protective conductor as equipotential bonding.
VI. DC connection
▪ Make sure PV modules have good insulation against ground.
i ▪ On the coldest day based on statistical records, the Max. open-circuit voltage of the PV modules
must not exceed the Max. input voltage of the inverter.
▪ Check the polarity of DC cables.
▪ Ensure that DC switch has been disconnected.
▪ Do not disconnect DC connectors under load.
1. Please refer to "DC Connector Installation Guide".
2. Before DC connection, insert the DC plug connectors
with sealing plugs into DC input connectors of the inverter
to ensure protection degree.
VII. Communication setup
▪ Separate communication cables from power cables and serious interference sources.
▪ The communication cables must be CAT-5E or higher-level shield cables. Pin assignment complies
i with EIA/TIA 568B standard. For outdoor use, the communication cables must be UV-resistant.
The total length of communication cable cannot exceed 1000m.
▪ If only one communication cable is connected, insert a sealing plug into the unused hole of sealing
ring of the cable gland.
▪ Before connecting communication cables, ensure the protective film or communication plate
attached to the communication opening on the inverter is sealed tightly.
