Control Cables

The control cables should be at least 20 AWG (.5 mm2) screened multicore cables, see Table 3-1. The maximum terminal wire size is 14 AWG (2.5 mm2) for the relay terminals and 16 AWG (1.5 mm2) for other terminals.

Galvanic Isolation Barriers

The control connections are isolated from the mains potential and the GND terminals are permanently connected to ground. See Figure 4-9.

The digital inputs are galvanically isolated from the I/O ground. The relay outputs are additionally double-isolated from each other at 300V AC (EN-50178).
