Grounding

All Factory Line devices must be grounded so that any possible interference is shielded from the data telegram and dis-

charged to ground potential.

A wire of at least 2.5 mm

must be used for grounding. When mounting on a DIN rail, the DIN rail must be connected with

protective earth ground using grounding terminal blocks. The module is connected to protective earth ground via the metal

header.

Please note that for operation with 1000 Mbps (Gigabit), cables with four twisted pairs (eight wires), which meet

the requirements of Cat 5 as a minimum, must be used.

Grounding protects people and machines against hazardous voltages. To avoid these dangers, correct instal-

lation, taking the local conditions into account, is vital.
