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

• 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.
