Grounding the RTU
The RTU includes a chassis ground lug to the left of the power supply modules.
Location of Chassis Grounding Lug
 Once you have installed the unit, run a ground wire (14 AWG protective conductor)
between the ground lug and a known good earth ground.
 Use stranded copper wire to earth ground and keep the length as short as possible.
 Clamp or braze the ground wire to the ground bed conductor (typically a stranded copper
AWG 0000 cable installed vertically or horizontally).
 Run the ground wire so that any routing bend in the cable has a minimum radius of 30.48
cm (12 inches) below ground and 20.32 cm (8 inches) above ground.
 If using one or more extension chassis for additional I/O capacity, ground each chassis
individually.
For more information on grounding or if your installation uses cathodic protection, refer to Site
Considerations for Equipment Installation, Grounding, and Wiring (D301452X012).
