Technical Description
A grounding conductor of 16 mm² cross-section is thus adequate for short-circuit
currents up to 10000 A.
6.2 DC Connection
6.2.1 Safety Precautions/Conditions
Connect a suitable battery to the DC side (see section 20 "Technical Data" (Page 155)).
DC must be connected observing all valid regulations (e.g. DIN VDE 0510, Rules for
Accumulators and Battery Systems).
6.2.2 Cable Protection
In addition to the DC circuit breakers within the Sunny Island 5048, install a separate
fuse as close as possible to your batteries. Install a suitable fuse plug for the fuse
according to the maximum specified DC current (e.g. NH1 with 250 A).
All safety and maintenance instructions provided by the battery
manufacturer must be heeded.
Use appropriate (insulated) tools for installation and wiring of the
batteries (danger of short circuits and arcing).
When connecting the battery, ensure that the cable has sufficient cross-
section and that the connections have the correct polarity.
The battery cables should be as short as possible. Long cables and insufficient
cable diameters reduce the system efficiency as well as the overload capabilities.
Do not lay the battery feed cables under plaster or in armored plastic pipes. Large
currents flow through the battery cables so that they can become very warm.
