Grounding
Galaxy
®
eCCB series displays do not require a local earth-
ground electrode.
The displays are designed so the most sensitive
components are isolated and an earth ground is not
required and is no longer recommended.
The displays still require a safety ground from the electrical
service panel for the primary power wires to comply with
national electric codes.
Please note that earth-grounding requirements for other
Daktronics products remain unchanged.
