Installation of the energy meter and the cable type current transformers
The energy meter and the current transformers must be installed in a distribution box. Depending on the position of
the current measurement, you will need to use the distributor for the house supply line (total current measurement) or
the sub-distributor for the building (section current measurement).
The energy meter is a standard top-hat rail module that can be placed on any DIN rail. The distance between the en-
ergy meter and the current transformers is determined by the length of the connection cables that are permanently
connected to the current transformers.
You will need the following tools and components for the installation:
Phillips screwdriver
Optional: Cable tie
(1 per transformer)
DANGER!
Dangerous electrical currents
Always observe the 5 safety rules:
1
Cut power source
2
Secure all cut-off devices
3
Verify absence of voltage
4
Ground and short-circuit
5
Cover or bar access to adjacent components under voltage
WARNING!
Electrical installation guidelines
The entire installation must be carried out by a qualified specialist electrical contractor!
The electrical supply cable must be disconnected from the power supply during the entire installation.
The connection to the electricity grid must only be established after the installation has been completed in
order to subsequently set up the energy meter (see “Setting up the energy meter” on page 19).
Proceed as follows:
1
Switch off the power supply to the house before
the distributor.
