6.2.1.2 Galvanic isolation barriers
The control connections are isolated from the mains potential and the GND terminals are permanently
connected to ground. See Figure 6-26.
The digital inputs are galvanically isolated from the I/O ground. The relay outputs are additionally double-
isolated from each other at 300VAC (EN-50178).
