General Purpose Switch Modules 6
34980A User’s Guide 189
After a five- to ten- second delay, remove the sheet metal cover from the
module and move the position of the jumper mounted on the module.
See the figure below for the jumper’s location on the module.
WARNING
Before changing the position of the jumper, remove external
connections from the module. Wait five to ten seconds to allow
the modules internal capacitors to discharge.
WARNING
Do not connect either the 34937A or 34938A module directly to a
mains power outlet. If it is necessary to switch a mains voltage or
any circuit where a large inductive load may be switched, you
must add signal conditioning elements to reduce the potential
transients before they reach the module or the Analog Buses.
