PSPs are available in four different versions. The differences are the
presence or not of the switch disconnector and the string connection type.
PSPs should be configured when placing the order using the
configuration model that can be found on the internet at the following

String-combs can be configured in different ways according to:
• Number of strings that can be connected
• Cable gland type or MC4 string input connector type
• Size of fuses
• Parallel string output cable gland
• Cable gland for the ground cable
