Safety Summary 

General Safety Precautions 

The following general safety precautions 
must be observed during all phases of 
operation of this instrument. Failure to 
comply with these precautions or with 
specific warnings elsewhere in this manual 
violates safety standards of design, 
manufacture, and intended use of the 
instrument. 
 
Keysight Technologies Inc. assumes no 
liability for the customer's failure to comply 
with these requirements. 
 
Before operation, review the instrument and 
manual for safety markings and instructions. 
You must follow these to ensure safe 
operation and to maintain the instrument in 
safe condition. 
 

Initial Inspection 

Inspect the shipping container for damage. If 
there is damage to the container or 
cushioning, keep them until you have 
checked the contents of the shipment for 
completeness and verified the instrument 
both mechanically and electrically. The 
Performance Tests give procedures for 
checking the operation of the instrument. If 
the contents are incomplete, mechanical 
damage or defect is apparent, or if an 
instrument does not pass the operator’s 
checks, notify the nearest Keysight 
Technologies Sales/Service Office. 
 
WARNING To avoid hazardous electrical 
shock, do not perform electrical tests when 
there are signs of shipping damage to any 
portion of the outer enclosure (covers, 
panels, etc.).

 
 

General 

This product is a Safety Class 1 product 
(provided with a protective earthing ground 
incorporated in the power cord). The mains 
plug shall only be inserted in a socket outlet 
provided with a protective earth contact. Any 
interruption of the protective conductor, 
inside or outside of the instrument, will make 
the instrument dangerous. Intentional 
interruption is prohibited. 
 

Environment Conditions 

This instrument is intended for indoor use in 
an installation category II, pollution degree 2 
environment per IEC 61010 Second Edition 
and 664 respectively. It is designed to 
operate within a temperature range of 10 to 
40 °C at a maximum relative humidity of 
80% for temperatures up to 31 °C, 
decreasing linearly to 50% relative humidity 
at 40 °C at an altitude of 2000 meters. 
 
This module can be stored or shipped at 
temperatures between -40°C and +70°C. 
Protect the module from temperature 
extremes that may cause condensation 
within it. 
 

Before Applying Power 

Verify that all safety precautions are taken. 
The power cable inlet of the instrument 
serves as a device to disconnect 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 rack mounted the rack must be 
provided with an easily accessible mains 
switch. 
 

 
 

Ground the Instrument 

Install the instrument so that the ON / OFF 
switch is readily identifiable and is easily 
reached by the operator. The ON / OFF switch 
is the instrument disconnecting device. It 
disconnects the mains circuits from the 
mains supply before other parts of the 
instrument. Or the detachable power cord 
can be removed from the electrical supply. 
Alternately, 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. 
 

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.
