8.1 Grounding CHASSIS
It is not necessary to use ground lugs on the rear of the GRANITE modules as long as the
GRANITE modules are clamped down tightly to the CHASSIS frame. In most cases, use a single
ground path to avoid ground loops.
When plugged into a properly grounded AC circuit, the CHASSIS is adequately grounded
through the ground pin on the AC plug. When using multiple wall-plugged CHASSIS, do not
daisy chain the CHASSIS grounds.
Connect at least one CHASSIS ground lug to vehicle ground, or earth ground for stationary
deployments.

8.2 Power bus
Terminals labeled Module Power are common. The power voltage plugged into one of these will
be distributed along this power bus. 24 VDC is recommended; however, voltage that is within the
required range of the connected modules is acceptable.
NOTE:
Measurement modules accept maximum voltage of 32 VDC.
