7.3 Connecting Grounds
7.3.1 System Chassis Ground
Connect the chassis ground wire to the chassis terminal
at the RCM. Follow electrical codes when selecting wire
size, maximum wire length, and maximum earth ground
resistance. When used in Zone 2 hazardous area
applications, use a 4 mm
2
wire with crimp style lug to
connect the chassis ground wire to earth ground.
Figure 7-1) Chassis Ground
The VC-8000 must be properly grounded to operate correctly. Be sure to adhere to
proper grounding practices, providing a single point ground and avoiding ground loops.
7.3.2 Single Point Ground (System Common to Chassis Connection)
To connect Chassis (GND) to System (Instrument) Common
(COM) insert the jumper between COM and GND as shown.
You can install the jumper at either the Power 1 or Power 2
plugs. Both work the same.
To isolate the internal instrument ground (COM) from earth
ground (GND) removing the jumper. An example of this
situation would be when using Zener safety barriers, or
when the internal system ground is connected to another
instrument ground.
