6.2.1 Mounting and Dismounting the Plexiglas Cover and Sliding
Plate
Regardless of the type of AC grid connection, the Plexiglas cover over the fuse load disconnection
unit and the sliding plate in the roof of the Sunny Central must be removed in order to install the
relevant copper bars. These components are put back on once the copper bars have been installed.
Instructions for mounting and dismounting these parts are provided in this chapter.
Damaged insulators
If an insulator becomes damaged, it must be replaced with an insulator of the same type
or model.
Observe the internal power supply connection
If the Sunny Central power supply is picked up internally at the AC connection, the internal
power supply must be connected prior to the installation of the AC copper bars (see
6.5.2 ”Connecting the Internal Power Supply” (page 74)).
WARNING!
Risk of death due to burns and electric shock when live parts are touched!
• Do not touch the live components of the Sunny Central, the power distribution grid or
the low-voltage grid.
• All safety precaution measures regarding the power distribution grid must be
observed.
• Only work on the device when it is switched off and voltage-free.
