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.
