Overview

Installation version 1

Fig. 1: Installation example: Simple home installation
If the installation environment requires Overvoltage
Category III (OVCIII), the input side of the external
power supply must be protected by means of protec-
tive circuitry (e.g. a varistor) that conforms to locally
applicable regulations.
Installation at high altitude
Sensor supply cables that are installed in electrical
installations at a height of over 2,000 m or must
conform to Overvoltage Category III (OVCIII) due to
their installation location must additionally be
insulated using heat-shrink tubing or suitable insula-
tion tubing with a dielectric strength of 20 kV/mm
and minimum wall thickness of 0.4 mm along the
entire length of cable between the sensor output
(housing) and the input terminal on the energy
manager.
