3.2 Electrical installation
Make sure that the unit is properly mounted and the process input and output are connected before making the
electrical connections.
This unit must be grounded.
The TCE requires a regulated DC power supply of 24V ±20% or a mains voltage of 100 to 240V AC, depending
on the version.
WARNING!
Never connect a 24V only version to the mains supply or vice versa!
The digital inputs and outputs are referred to GND and to the ground potential of the DC supply (= negative pole).
The AC supply terminals are electrically isolated from all inputs and outputs.
The ground potential GND is connected to protective ground via a 1k.
For connecting the TCE, shielded cables must be used. The shield should be connected to the case. If in bigger
systems the shield must not present a DC connection for avoiding high ground loop currents, make the ground
connection of the shield via a capacitor of e. g. 100nF.
Make sure that the flow meter is grounded.
WARNING!
Improper grounding and shielding may lead to bad EMC behavior or danger to your health!
NOTE
Make sure that all cable and wires are connected and fixed properly before applying power to the TCE.
