CAUTION
ESD Hazard! ESD (Electrostatic Discharge) can cause software crashes, data and/or com-
munications problems. Failure to use proper ESD procedures will cause damage to elec-
tronic components (example: PCBs). ESD problems can be minimized by maintaining all
machine ground connections, ensuring the proper handling of circuit boards/ sensors
- Use ESD protection when working near PCBs. Failure to use ESD protection is likely to
result in a PCB failure (
result in a PCB failure (
