☐ The Sunny Home Manager 2.0 is supplied with current via the line conductor
L1. At least the line conductor L1 and the neutral conductor must be connected
in order that the Sunny Home Manager 2.0 switches on.
☐ When using fine stranded wire, bootlace ferrules must be used.
☐ The screw terminals must be retightened after six to eight weeks.
Installation using the integrated measuring unit
The following figure shows a connection example in TN and TT grid configurations
in the case of installation at the grid-connection point when using the integrated
measuring unit (recommended). For exact connection specifications, contact your
electric utility company.
Procedure:
1. Connect the conductors to the Sunny Home Manager 2.0. Observe the permit
-
ted connection cross-section and torque for screw terminals (see Section "Tech
-
nical Data"):
• In a three-phase utility grid, connect the line conductors L1, L2 and L3 and
the neutral conductor to the Sunny Home Manager 2.0 in accordance with
the wiring diagram.
• In a single-phase utility grid, connect the line conductor L1 and the neutral
conductor to the Sunny Home Manager 2.0 in accordance with the wiring
diagram.

SAFETY INFORMATION
DANGER
Danger to life due to electric shock
Lethal voltages are present in the live components.
• Disconnect the connection point from voltage sources and make sure it
cannot be reconnected.
• Before performing any work on the Sunny Home Manager 2.0, discon
-
nect the grid side from all voltage sources using an installed disconnect
switch.
• Ensure that the conductors to be connected are de-energized.
• Only use the Sunny Home Manager 2.0 in a dry environment and keep
it away from moisture.
• Install the Sunny Home Manager 2.0 in the switch cabinet only and en
-
sure that the connection areas for the line conductors and the neutral
conductor are behind a cover or have contact protection.
• Disconnect the Sunny Home Manager 2.0 from voltage sources before
cleaning. The Energy Meter must be cleaned with a dry cloth only.
• Observe the prescribed minimum clearance between the network cable
and live installation components, or use suitable insulation.
DANGER
Danger to life due to electric shock if external disconnect switch is
missing
Lethal voltages are present in the live components of the
Sunny Home Manager 2.0.
• Install
an
external
disconnect
switch
between
the
Sunny Home Manager 2.0 and the grid-connection point. The external
disconnect switch must be close to the Sunny Home Manager 2.0 and
easily accessible.
WARNING
Danger to life due to electric shock
Overvoltages (e. g. in the case of a flash of lightning) can be further con
-
ducted into the building and to other connected devices in the same net
-
work via the network cable if there is no overvoltage protection.
• Ensure that all devices in the same network are integrated in the existing
overvoltage protection.
• When laying the network cable outdoors, attention must be given to suit
-
able overvoltage protection at the network cable transition outdoors to
the network inside the building.
WARNING
Risk of fire due to dirty or oxidized contact surfaces of live alumi
-
num conductors
Connecting dirty or oxidized contact surfaces with aluminum conductors re
-
duces the ampacity of the live terminals, thereby increasing the transition re
-
sistances. This can cause components to overheat and catch fire.
• The contact surfaces are to be cleaned, brushed, and treated with acidic
and alkaline substances (e.g. petroleum jelly or special thermal grease).
WARNING
Fire risk
If a fuse is missing or incorrect and a fault occurs, a fire may be caused. This
can result in death or serious injury.
• Fuse the Sunny Home Manager 2.0 line conductor with a fuse or a se
-
lective circuit breaker with max. 63 A.
