SMA SB 1300TL - Manual (Page 28)

Additionally required material (not included in the scope of delivery):
☐ Ring terminal lug M6
☐ 1 grounding cable
Cable requirement:
☐ Grounding cable cross-section: max. 16 mm²
Procedure:
1. Strip the grounding cable insulation.
2. Thread the ring terminal lug onto the grounding cable.
3. Align washer, grounding cable with ring terminal
lug and conical spring washer on the cylindrical
screw M6x12. The teeth of the conical spring
washer must be facing the metal shackle on the
inverter.
4. Insert the cylindrical screw through the metal shackle on the inverter and screw it onto the wall
mounting bracket (torque: 6 Nm).
6.4 Connecting the Fault Indicator Relay
You can use the fault indicator relay to have inverter errors displayed or reported. This requires a
parallel connection. Alternatively, you can choose to have fault-free operation displayed or
reported. This requires a series connection. You can connect several inverters to one fault indicator
or operation indicator. You must connect the fault indicator relay of several inverters in parallel.
In case of critical disturbances, the fault indicator relay will close immediately and trip the warning
signal through the connected load. In case of non-critical disturbances, the fault indicator relay will
only close after several flashing cycles of the yellow LED. When the inverter reconnects to the utility
grid, the fault indicator relay opens again.
Error message required by standard
In some countries, signaling of errors is required by standards, e.g. IEC 62109-2. In order to
meet the standard requirement, take one of the following measures:
• Connect a display device to the fault indicator relay which signals either an error or the
undisturbed operation of the inverter.
• Activate the error alarm in Sunny Portal (for information on receiving error alarms via
Sunny Portal, see the Sunny Portal user manual at www.SunnyPortal.com). This requires
the inverter to be registered in Sunny Portal.
