The detachable power cord is the instrument disconnecting device. It
disconnects the mains circuits from the mains supply before other parts of
the instrument. The front panel switch is only a standby switch and is not a
LINE switch (disconnecting device). The instrument power cord does not
disconnect or de-energize external circuits connected to the analog bus,
terminal blocks or modules.
Keysight Customers utilizing the Open Platform Test Systems are classified
as follows and require the user to have the appropriate skillset:
Operator: Interacts with the test system in a production environment,
selection of test sequences, defining variables, running tests (test results,
test statistics, control of marking devices)
Supervisor: Includes access to maintenance functions and utility sequences
(control of hardline system functions, access to test area
Developer: Full access
Dangerous voltage levels capable of causing death, may be present on a
channel. Use extreme caution when handling and testing and adjusting this
instrument. Any voltages greater than 30 Vrms, 42.4 Vpeak and 60 Vdc are
considered hazardous (IEC 61010-1).
The maximum common mode input to any one system component within the
system installation is not to exceed the maximum stated ratings.
When interconnecting system components, the overall system maximum
allowable input rating of the system would default to the lowest rating of any
one system component.
