SMA Solar Technology AG 6 Electrical Connection
Installation Manual SI80H-60H-OffGrid-IA-en-11 55
If you are using a multi-function relay, always connect it as follows:
Additionally required material (not included in scope of delivery):
☐ 2 bootlace ferrules
Requirements:
☐ The technical requirements of the multi-function relay must be met (see Section 12"Technical
Data",page144).
☐ Conductor cross-section: 0.2 mm² ... 2.5 mm²
1. Break through the cable feed-through plate at a suitable position using a sharp object.
2. Strip the insulation from the cable and press bootlace ferrules onto the wires.
3. Lead the cable through the hole in the cable feed-through plate into the off-grid inverter.
Assignment of the multi-function relays of the slaves
In case of a fault, the multi-function relays of the slaves switch less reliably than the multi-function
relays of the masters. If a fault occurs, the slaves wait for error confirmation from the master.

Danger to life from electric shock due to incorrect insulation
• Cut the silicone tube to the length of the cable.
•Pull the silicone tube over the cable.
☑ The cable is double-insulated.
• Lead the cable into the off-grid inverter making sure that it cannot touch any data cables.
