NOTE! Take into account local specifications when configuring cable cross sec-
tions.
Carefully clean off the oxide layer of the stripped end of the cable, e.g., using a knife.
After removing the oxide layer of the cable end, rub in a neutral grease, e.g., acid- and
alkali-free Vaseline.
Then immediately connect it to the terminal.
CAUTION! Risk of possible damage to the inverter! Check the polarity and volt-
age of the solar module strings before connection. The voltage must not exceed
the following values:
Symo 10.0-3 – 12.0-3 208–240
- 0–11154 ft (0–3400 m) = 600 V
Symo 10.0-3 – 24.0-3 480
- 0-6561 ft (0-2000 m) = 1000 V
- 6531–8202 ft (2000–2500 m) = 950 V
- 8202–9842 ft (2500-3000 m) = 900 V
- 9842–11,154 ft (3000-3400 m) = 850 V
