Installation

Security measures

Installation of the device should be carried out by a qualified installers with
knowledge and experience in the field of electrical installations. Please read the
operating instructions before installation.
All installation work must be carried out with the supply voltage switched off. Ensure
that the wires are carefully tightened – loose wires can lead to sparking, or in the
extreme case to ignition of the device.
Installation
The meter should be connected to the electrical installation according to the following diagram.
It is recommended to protect the current circuit of the meter with a fuse with a level
of protection adapted to the level of load current, but not exceeding the maximum
current of the meter (100 A).
The diameter of the wires must be adapted to the value of the currents flowing
through the current circuit of the meter (terminals 1 – 3). The minimum
recommended diameter of current wires is 4 mm
2
mm . Approximate diameters of the wires depending on the load current are
presented in the table below:
