Functional Ground on the DIN Rail

The DIN rail for your LT system is common with the functional ground plane and must be

mounted on a conductive backplane.

Shielded Cable Connections

Cables carrying the fast I/O, analog I/O, and Serial communication signals must be

shielded. The shielding must be securely connected to ground. The fast I/O and analog I/O

shields may be connected either to the functional ground (FE) or to the protective earth

ground (PE) of your LT.

NOTE: The functional ground of the Ethernet connection is internal.

WARNING

UNINTENDED EQUIPMENT OPERATION

When connecting DIN rails, connect the DIN rails to functional ground (FE).

Failure to follow these instructions can result in death, serious injury, or equipment

damage.

WARNING

ACCIDENTAL DISCONNECTION FROM PROTECTIVE GROUND (PE)

 Do not use the grounding bar to provide a protective earth ground (PE).

 Use the grounding bar only to provide a functional ground (FE).

Failure to follow these instructions can result in death, serious injury, or equipment

damage.

DANGER

HAZARD OF ELECTRIC SHOCK

Make sure that CANopen and Modbus cables are securely connected to the protective

earth ground (PE).

Failure to follow these instructions will result in death or serious injury.
