WARNING
Make sure the instrument that you are installing is in a powered-down state
with all cables unplugged. Failure to install an instrument in a discharged
state may cause personal injury or death from electrical shock. Do not
exceed the maximum specifications of the switching module.
To prevent electrical shock, observe the following safety precautions:
•
Both ends of the cable must be connected before applying any power
to the system.
•
Remove all power in the system before connecting the cable to a
switching module or external circuitry.
•
Both D-sub connector shells of this cable must be connected to a
safety earth ground. A shock hazard exists when voltage levels greater
than 30V RMS, 42.4V peak, or 60V DC are present.
