APx555 B Series Audio Analyzer: Safety

Safety

Safety Information

Do NOT service or repair this equipment unless properly

qualified. Servicing should be performed only by a quali-

fied technician or an authorized Audio Precision distributor.
Do NOT defeat the safety ground connection. This equip-

ment is designed to operate only with an approved three-

conductor power cord and safety grounding. Loss of the

protective grounding connection can result in electrical

shock hazard from the accessible conductive surfaces of this

equipment.
Do NOT exceed mains voltage ratings. This equipment is

designed to operate only from a 50–60 Hz ac mains power

source at 95–264 Vac nominal voltage.
For continued fire hazard protection, fuses should be

replaced ONLY with the exact value and type indicated on

the rear panel of the instrument and discussed on page 20 of

this manual.

The International Electrotechnical Commission

(IEC 1010-1) requires that measuring circuit terminals used

for voltage or current measurement be marked to indicate

their Measurement Category. The Measurement Category is

based on the amplitude of transient or impulse voltage that

can be expected from the AC power distribution network.

This product is classified as Measurement Category I,

abbreviated “CAT I” on the instrument front panel. This

product should not be used within Categories II, III, or IV.

The 2-channel input module measurement terminals are

rated for a maximum voltage of 230 Vpk to ground, and a

signal input of 160 Vrms unbalanced, 300 Vrms balanced.

These terminals are intended to be used for the measure-

ment of audio signals only.
Do NOT substitute parts or make any modifications with-

out the written approval of Audio Precision. Doing so may

create safety hazards. Using this product in a manner not

specified by Audio Precision can result in a safety hazard.
