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 does not have any internal
fuses. The voltage 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.

Install the mains power supply unit of the energy
manager at a minimum distance of 0.5 HP from
its housing.

Protect all electrical interfaces from direct/indi-
rect contact.
