Installation and connection
Preparing the distribution cabinet
US
If the installation environment requires Overvoltage
Category III (OVCIII), the input side of the external
power supply must be protected by means of
FC
protective circuitry (e.g. a varistor) that conforms to
locally applicable regulations.

For information on the space needed by the energy
manager:

e For installation, the energy manager requires
horizontal pitch 11.5 on a DIN rail in the
TR
distribution box.
e Install the power supply unit of the energy
manager at a minimum distance of horizontal
RU
pitch 0.5 from the energy manager housing.
e Protect all electrical interfaces from direct/
UK indirect contact.

Installation in the distribution cabinet
b All cable connections are connected to the energy
manager.
b The DIN rail holder on the housing of the energy
manager is unfastened.
1. Position the DIN rail holder on the DIN rail in the
distribution box at an incline.
2. Tilt the housing of the energy manager and place
it level on the DIN rail.
3. Fasten the DIN rail holder on the housing of the
energy manager.

4. Check that the energy manager is firmly secured
to the DIN rail.
Installing the current sensors
Install the current sensors for measuring the overall
current of the business/household after installing the
main fuse on the relevant main phases. The energy
flows must not yet have been divided into further
sub-circuits.
f Refer to chapter "Overview" on page 4.
e Adhere to the maximum permitted cable length
of 9.8 ft. (3 m) per current sensor.
e Select an installation location where cables can
run straight and pay attention to the direction of
measurement (arrow pointing towards the power
consumer).
e Insert the installation cable in the current sensor
and close the cap of the sensor.
If sensor cables need to be extended, use the same
type of cable if possible.
If the installation environment requires the use of the
optional wall-mounted distribution box, the cables
must be routed to the distribution box through
suitable cable routing systems (empty conduits,
cable ducts, etc.).
