Connection to the power grid

Installing circuit breakers
Information
Line protection fuses are not included in the scope
of supply and must be installed by a qualified electri-
cian.
The energy manager has no internal fuses. The volt-
age measurement, external power supply and relay
inputs must therefore be fitted with suitable backup
fuses.
– Use of the energy manager requires overcurrent
protection for all supply leads. Make sure you se-
lect fuses with a sensitive trigger characteristic.
–
Fuses are selected based on what components
are available in the country of use.
–
Use components with the lowest trip current and
shortest trip time.

e
To install the energy manager inside the distri-
bution cabinet, allow a horizontal pitch (HP) of
11.5 on a DIN rail.
e
Install the mains power supply unit of the energy
manager at a minimum distance of 0.5 HP from
its housing.
e
Protect all electrical interfaces from direct/indi-
rect contact.
