Safety Considerations
WARNING, CAUTION, and NOTE must be observed to ensure the safety of the service
personnel or to prevent damage of the system and any system component (instrument).
WARNING Several procedures described in this chapter are performed with power applied.
Service personnel must be aware of the hazards involved, and perform the
procedures carefully and safely to prevent electric shock hazard.
When troubleshooting can be performed without power applied, turn the power off.
After repairs are completed, make sure all safety features are intact and all necessary
parts are connected to their protective grounds.
WARNING To ensure your safety, use the lockout mechanism of the PDU if you leave the Agilent
41000 while troubleshooting the power supply. Set the PDU main switch to off. This
prevents the Agilent 41000 from being accidentally turned on.
For the turning on and off procedure, see “Turning the PDU On and Off” on page 2-24.
Checking Power Distribution Unit (PDU)
If the Agilent 41000 loses power, check the operation of the power distribution unit (PDU)
and the emergency off (EMO) panel.
