Agilent Technologies N8201A manual Fuses and Circuit Breakers, Maintenance

6Service, Support, and Safety Information

C A U TI O N	The detachable power cord is the disconnecting device. It disconnects the mains
	circuit from the mains supply before other parts of the instrument or system. The
	instrument front panel switch is only a standby switch and is not a line switch.

Fuses and Circuit Breakers

Refer to individual instrument manuals for detailed information on operator accessible fuses.

WA R N I N G	Use only fuses with the required rated current, voltage, and specified type
	(normal blow, time delay). Do not use repaired fuses or short-circuited fuse
	holders. To do so could cause a shock or fire hazard.

WARNING	For continued protection against fire hazard, replace fuses and circuit breakers
	only with the same type and ratings. The use of other fuses or circuit breakers or
	materials is prohibited (IEC 348 clause 17.3.5.d).
WARNING	The premise wiring should have a system-dedicated circuit breaker in the mains
	wiring for installation of the system.

Agilent system cabinet power strips are equipped with a thermal circuit breaker for each power phase. If one phase shorts or overloads, one or both of the circuit breakers in the power strip trip. Unplug the power strip before trying to locate and correct the electrical problem, then reset both circuit breakers on the power strip to restore power to the cabinet.

Maintenance

WARNING	To prevent electrical shock, disconnect the instrument and/or system from
	mains before cleaning. Use a dry cloth or one slightly dampened with water to
	clean the external case parts. Do not attempt to clean internally.

Safety symbols and Instrument Markings

Symbols and markings in manuals and on instruments alert you to potential risks, provide information about conditions, and comply with international regulations. Table 6 defines the symbols and markings you may find in a manual or on an instrument.
