6.5.4.5 Application Note
In addition to the notes in chapter 4, please regard the following:
 Make sure that the GND of the analog signals is connected to the 0V terminal. Otherwise
the measurement will loose precision.
 The 2 potential-free relays (Relay 5 + 6) have to operate on the same voltage level 230VAC
or 24VAC or 24VDC. A mixture of different voltage levels is not allowed.
 Current measurement is only active when one wire (L or N) is carried through the current
sensor only one time.
 On the backside of the PCB the contacts are touchable, so you have to keep the PCB in a
housing.
 This module support relay contacts. For the two potential free depending on the electrical
application, the user has to install sufficient additional components to fulfill the
EMC-standads and the requirements of the relay producer (see relay datasheet), especially
when driving inductive/capacitive or high inrush current loads. The other four have inbuild
RC-Parts on the Board.
