WARNING

CAUTION

Keysight N4373E Lightwave Component Analyzer Setup Guide

To prevent electrical shock, disconnect the instrument 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.

Using controls or adjustments or performing procedures other than

those specified in the documentation supplied with your equipment can

result in hazardous radiation exposure.

This product complies with over-voltage Category II and Pollution

Degree 2.

Ventilation requirements: When installing the product in a cabinet, the

convection into and out of the product must not be restricted. The

ambient temperature (outside the cabinet) must be less than the

maximum operating temperature of the product by 4 °C for every

100 watts dissipated in the cabinet. If the total power dissipated in the

cabinet is greater than 800 watts, then forced convection must be used.

Install the instrument so that the power switch is readily identifiable and

is easily reached by the operator. This is the instrument disconnecting

device. It disconnects the mains circuit from the mains supply before

other parts of the instrument. Alternatively, an externally installed switch

or circuit breaker (which is readily identifiable and is easily reached by

the operator) may be used as a disconnecting device.

Always use the three-prong AC power cord supplied with this

instrument. Failure to ensure adequate earth grounding by not using this

cord may cause instrument damage.
