Connection Requirements:
Carefully clean off the oxide layer of the stripped end of the cable, e.g., using a knife.
IMPORTANT Do not use brushes, files or sandpaper. Aluminum particles may get stuck
and can transfer to other cables.
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.
Repeat the steps above whenever the cable is disconnected and then reconnected.

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
IMPORTANT! You should only remove the minimum number of knockouts required for the
available cables.
