5.4 Connecting DC Input Power Cables
Prerequisites
Issue 07 (2019-06-30)
The cable colors in figures are for reference only. Select appropriate cables according to the local
standards.
Before connecting DC input power cables, ensure that the DC voltage is within the safe
range (lower than 60 V DC) and that the two DC switches on the SUN2000 are OFF.
Otherwise, the high voltage may result in electric shocks.
When the SUN2000 is grid-tied, it is not allowed to maintain DC input power cables, such
as connect or disconnect a string or a module in a string. Otherwise, electric shocks may
occur.
