12 Stratix 2000 Ethernet Unmanaged Switch
Rockwell Automation Publication 1783-IN010A-EN-P - June 2013
Ground the Switch
The switch has two grounding points, as follows:
•
Functional Earth Ground (FE) in the power connector.
•
Protective Ground (PE) on the switch housing.
•
Grounding resistance for PE must be less than 2.5 .
•
For proper grounding, use a suitable ring terminal for the chassis PE ground screw,
and minimum 2.5 mm

(14 AWG) wire.
•
Torque must not exceed 1.82 N

m (16.10 lb

in).
ATTENTION: This product is intended to be mounted to a well-grounded mounting surface, such a
metal panel. For safety and maximum noise immunity, the switch must be grounded by using the
Protective Ground (PE) grounding screw on the housing. Functional Earth ground (FE) is internally
connected to the PE ground. It may be used to ground the DC power supply, for example. The PE
chassis ground must be connected to a reliable earth ground at all times.
