Galvanic Isolation of the Power Supply
If galvanic isolation of the power supply line from the output signals is
needed, DMT340 can be ordered with optional galvanic isolation
module. This module prevents harmful grounding loops.
Installation
NOTE Galvanic isolation module is not needed when using the AC power
supply module. Note also that these two modules are physically
incompatible to be installed at the same time. If both modules are
installed, there is no room to close the transmitter cover completely.
