WARNING
Danger to life due to high voltages
High voltages are present in the off-grid system
and in the Sunny Island. The Sunny Island can
start on its own from standby.
• Turn off or disconnect the components in the
following order:
– Sunny Island
– All loads, AC sources, external energy
sources and DC sources
– Miniature circuit-breaker for AC sources
and the external energy source in the
sub-distributions
• Switch the DC miniature circuit-breaker to the
Off position
or
• Open the switch-disconnectors of the Bat-
Fuse.
• Ensure that the device cannot be reconnect-
ed.
• Wait at least 15 minutes. This allows the ca-
pacitors to discharge.
• Open the enclosure lid of the Sunny Island
and ensure that no voltage is present.
• Ground and short-circuit the AC conductors.
• Cover or safeguard any adjacent live compo-
nents.
2. NOTICE
Destruction of the connection jack due to im-
proper installation
• Ground yourself before touching any compo-
nents.
• Position the interface above the interface slot
and adjust it vertically to it. Pay attention to
different plug sizes.
• Position the interface on the connection jack
and press with slight pressure. This avoids
damage of the pins in the connection jack.
