Earthing Recommendations - Equinox Systems PPM3 MK2 User Manual

4.6.4 Earthing recommendations

To avoid catastrophic damage to PC, programmer or target system:
•
Ensure that both your target system and PC are connected to a common earth point
•
Make sure that all interconnections are made before applying power to PC and target system
•
If you are using a laptop or PC which is not connected to mains earth, it is recommended that
you make a hard-wired connection from the COM port D-connector shell and the target system
to a common earth point
•
Avoid plugging and unplugging ISP connector while either the PC or Target System is
powered up
•
Please ensure that any devices connected to the user target system are also properly
grounded to the same common earth point
Warning!
Any damage caused to the programmer by Electrostatic Discharge (ESD) through inadequate
earthing is not covered under the warranty of the product.
