Safety Requirements Safety Summary
8 Agilent 81133A/81134A Pulse Generator User’s Guide, September 2008
Before Applying Power
Verify that all safety precautions are taken.
The power cable inlet of the instrument is used to disconnect the 
instrument from the mains in case of hazard. The instrument must 
be positioned so that the operator can easily access the power 
cable inlet.
When the instrument is mounted in a rack, the rack must be 
provided with an easily accessible mains switch.
Ground the Instrument
To minimize shock hazard, the instrument chassis and cover must 
be connected to an electrical protective earth ground. The 
instrument must be connected to the ac power mains through a 
grounded power cable, with the ground wire firmly connected to 
an electrical ground (safety ground) at the power outlet. Any 
interruption of the protective (grounding) conductor or 
disconnection of the protective earth terminal will cause a 
potential shock hazard that could result in personal injury.
Do not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable gases 
or fumes.
Do not Remove the Instrument Cover
Operating personnel must not remove instrument covers. 
Component replacement and internal adjustments must be made 
only by qualified personnel.
Instruments that appear damaged or defective should be made 
inoperative and secured against unintended operation until they 
can be repaired by qualified service personnel.
