Caution, risk of electric shock

Caution, risk of danger (refer to this

manual for specific Warning or Caution

information)

4 Keysight 34980A Service Guide

Ground the Instrument

This product is provided with protective earth terminals. To minimize shock

hazard, 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

Only qualified, service-trained personal who are aware of the hazards involved

should remove instrument covers. Always disconnect the power cable and any

external circuits before removing the instrument cover.

secured against unintended operation until they can be repaired by qualified

service personnel.

Keysight 34980A Service Guide 5

Environmental Conditions

Keysight 34980A is designed for indoor use in an installation category II and low

condensation environment. Do not use in locations where conductive dust or

electrolytic salt dust may be present. Table below shows the general

environmental conditions for this instrument. Refer to the product data sheet at

https://literature.cdn.keysight.com/litweb/pdf/5989-1437EN.pdf for more

information on the instrument general specifications.

General specifications Requirement

Temperature Operating condition: 0°C to 55°C

Storage condition: -40°C to 70°C

Humidity Up to 80% R.H. at 31°C (non-condensing), decreasing

linearly to 50% R.H. at 40°C (non-condensing)

Altitude Up to 2,000 m

Pollution degree 1 or 2

NOTE

When used in pollution degree 1 conditions, the maximum voltage rating for the

Analog Buses is 300V. When used in pollution degree 2 conditions, the

maximum voltage rating is 100V. If conditions change, ensure that condensation

has evaporated and the instrument has thermally stabilized until pollution

degree 1 conditions are restored before turning on power to the equipment.

NOTE

Pollution Degree 1: No pollution or only dry, non-conductive pollution occurs.

The pollution has no influence (on insulation) (IEC 61010-1 2nd Edition).

Pollution Degree 2: Normally only non-conductive pollution occurs.

Occasionally, a temporary conductivity (leakage current between isolated

conductors) caused by condensation can be expected (IEC 61010-1

2nd Edition).
