Implementing the emergency circuit(s)
Basics for the formation of the emergency circuits:
•
For systems with emergency power capability, the power distribution must be
separated into emergency power authorised and not emergency power authorised
parts.
•
All components within the emergency power authorised part must be clearly
identified by lettering (or graphic symbols).
At any time observe further local and national requirements and guidelines
regarding emergency power supply!
When undertaking electrical work on the distributor in the building, the following must be
taken into account, among other things:
1-
How is the wiring set up to the desired backup consumers?
-
Is independent wiring already in place?
-
Do the existing circuits include electrical consumers that should not be supplied
with power in backup operation?
-
Can the existing wiring be split?
-
If the circuits cannot be split, the connected wattage of the consumers which
should not be supplied with backup power needs to be taken into account. If
loads are too high, the circuit breaker for the sonnenProtect-Plus will trip, and
then none of the electrical consumers in the backup circuit will be supplied with
power.

Wiring procedure for the electrical installation
Important:
The mains grid supply must be connected directly to the sonnenProtect-Plus,
and from there, to connect to two sub-circuits: one for normal domestic loads and one for
the essential loads. Note that the essential loads which were previously part of the normal
loads, must now be isolated as a sub-circuit. This sub-circuit as the essential loads are wired
in a way so they will be specifically powered from the sonnenProtect-Plus during emergency
operation.
Carry out the steps in the following order to ensure the correct electrical installation of the
sonnenProtect-Plus:
