Connection Procedure - SMA SUNNY MINI CENTRAL 6000TL Installation Manual

SMA Solar Technology AG

Connection Procedure

DANGER!
Danger to life due to high voltages in the Sunny Mini Central!
• Before connecting the PV generator, ensure that the line circuit breaker is switched
off.
1. Remove the Electronic Solar Switch by pulling it
downwards and slightly towards the wall.
NOTICE!
Excessive voltages can destroy the measuring device!
• Only use measuring devices with a DC input voltage range up to at least 700 V.
2. Check the connection cables of the solar modules
for correct polarity and that the maximum input
voltage of the Sunny Mini Central is not exceeded.
Check the system design if the open circuit voltage
of the solar modules is less than 10 % below the
maximum input voltage of the Sunny Mini Central!
NOTICE!
The Sunny Mini Central could be irreparably damaged by overvoltage!
If the voltage of the solar modules exceeds the maximum input voltage of the Sunny Mini
Central, it could be irreparably damaged by overvoltage.
All warranty claims become void.
• Do not connect strings to the Sunny Mini Central with open circuit voltage greater
than the maximum input voltage of the Sunny Mini Central.
• Check the system design.
3. Check the strings for ground faults, as described in section 9.1 „The Red LED is Continuously
On" (54).
