EM Test esd NX30
Instruction Manual V 1.00.7 12 / 33
4.2.4 Remote triggering (esd NX30 only)
This port is indented to allow the user to connect external signals in order to remote control the esd NX30 generator, as well
as to connect external accessories like the charge removing device. See tables and graphs below for detailed signal descrip-
tion and drive circuitry information.
WARNING
Care has to be taken that the cable used to connect to this port is made with good shielding concept.
The shield itself needs to be linked with the housing such as to prevent any ESD hazard to the con-
troller board.
