4. Check that the energy manager is securely en-
gaged on the DIN rail.
Install current converter
NOTICE
Incorrect direction of measurement of the current
converter
Installing the current converter with the incorrect di-
rection of measurement can lead to incorrect results
and malfunctions.
e
Observe direction of measurement of the current
converter (Fig. 15, yellow arrows).
Install the current converters for measuring the total
current of the business premises/household in the
relevant main phases downstream of the main fuse.
The energy flows must not yet have been divided into
further sub-circuits.
g Refer to chapter "Overview" on page 43.

e
Make sure that all materials that protect against
corrosion are removed from the current con-
verter.
e
Adhere to the maximum permitted cable length
of 3.0 m for each current converter.
e
Select an installation location that allows cables
to be routed straight, and pay attention to the di-
rection of measurement (arrow pointing towards
the load) ((Fig. ), yellow arrow).
e
Insert the installation cable in the current con-
verter and close the converter cap ((Fig. 28),
yellow arrow).
e
Make sure that the current converter actually has
a higher rated current than the circuit breaker.
e
First insert the current converter cables in the
connectors, then insert the connectors in the
sockets of the device.
Information
Make a note of the type of current converter, its
connection position in the energy manager, and the
phase (e. g. L1 or L2) to which the current converter
was attached. You will need this information for con-
figuring the current converters in the Web Applica-
tion.
If you need to extend the measurement leads, use the
same type of lead if possible.
If the installation environment requires the use of
the optional wall-mounted distribution box, route the
leads into this distribution box via suitable cable
guide systems (empty conduits, cable ducts, etc.).
