Frame ground FG
{{@169#bkmrk-frame-ground-fg}}

Electronic circuits are constantly prone to electrostatic discharge ESD. Redisage Electronics modules feature a design for the frame ground terminal block FG. The frame ground provides a path for bypassing ESD, which provides enhanced static protection ESD abilities and ensures the module is more reliable.{{@169#bkmrk-electronic-circuits-}}

Connecting FG terminal block to the earth ground will bypass the ESD disturbances outside the device so will provide a better level of protection against ESD.

Frame Ground FG connection reference drawing is provided below.{{@169#bkmrk-frame-ground-fg-conn}}

If earth ground is not available FG can be left floating or can be connected with power supply GND.{{@169#bkmrk-if-earth-ground-is-n}}
