1.3 General Safety Instructions

The Sunny Island is only suitable for installation in closed rooms.

Therefore do not expose it to humidity, rain or direct sunlight.

The inverter is designed for use in places up to 2000 m (6561 ft)

above sea-level.

Make sure there is sufficient air circulation in the battery room. Bat-

teries can develop an explosive atmospheres in normal operation.

Use specialized tools when mounting and wiring the storage battery

(risk of short circuit).

As a precaution against injuries wear suitable clothes for handling

heavy and bulky devices when mounting and removing the Sunny

Island (such as working gloves and safety shoes).

The device may only be opened, installed and serviced by a qualified

electrician. Even when disconnected there can be high touch volt-

ages within the device. Please see our detailed description of how to

handle the Sunny Island and closely follow all instructions!

Under certain circumstances the Sunny Island may start up autono-

mously! Keep this in mind when working on the island grid and al-

ways switch off the AC fuses of all Sunny Islands in the island grid!
