4. Check that the energy manager is firmly at-
tached to the H-rail.
Installing current sensors
NOTICE
Incorrect measuring direction of the sensor
Installing the sensors contrary to the measuring di-
rection can lead to false results and malfunctions.
e
Note the measuring direction of the sensor (Fig.
15, yellow arrows).
The current sensors for measuring the total cur-
rent of the plant/household must be installed down-
stream of the main fuse on the relevant main phases.
No distribution of the energy flows into further sub-
circuits should have taken place yet.
g Refer to chapter "Overview" on page 8.

e
Adhere to the maximum permitted cable length
of 9.8 ft. (3 m) per current sensor.
e
Select an installation location with straight-
routed cables and observe the direction of meas-
urement (arrow pointing towards the electrical
load) (, yellow arrows).
e
Insert the installation cable into the current sen-
sor and close the cap of the current sensor (,
yellow arrow).
e
Make sure that the rated current of the current
sensor is actually higher than that of the circuit
breaker.
e
Current sensor cables should be inserted into
the plug connector first and only then should
the plug connecter be inserted into the device
interfaces.
Information
Note the current sensor type, the connection position
on the energy manager and the phase to which the
current sensor was attached. You will require this
information to configure the current sensors in the
Web Application.
If measurement cables must be extended, use the
same cable type where possible.
If the installation environment requires the use of an
optional wall-mounted distributor, the cables must
be guided through suitable cable routing systems
(cable ducts, channels etc.) into the wall-mounted
distributor.
