Earthing for function and safety
For functional and/or safety reasons you may wish to EARTH the casing of your Electron
Plus instrument. This is not necessary under most normal operating conditions.
In this case, we recommend loosening (and re-tightening) the M3 stainless steel chassis
screw (2mm HEX drive) and fitting an earthing wire using either ring terminal or spade
terminal.
If in doubt please contact Electron Plus for further details.
Caution
USB 0V, rear panel, front panel, casing and any external power supply
0V are all the same potential and connected via low impedances (PCB,
metalwork, etc.) - Avoid creating 'ground loops' with your setup!
Note
Some earlier production ASA100 units may have a TORX T10 headed
stainless steel earthing screw fitted instead of the 2mm HEX drive
type. If you would like a 2mm HEX drive screw (our part# SCREW014),
please contact the factory and we will supply one free-of-charge.
