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

Electronic circuits are constantly prone to electrostatic discharge ESD.{{@169#bkmrk-electronic-circuits-}}

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.

Connecting FG terminal block to the earth ground will bypass the ESD disturbances outside the device so it 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 it can be connected with power supply GND.{{@169#bkmrk-if-earth-ground-is-n}}

In the C22 converter user should use only RS232 or only RS485 interface of one port as they occupy the same internal bus of the device.
