3.4.4 

Electrical Safety 

The Servomex SpectraScan Gas Analyzer is powered by voltages that could pose a hazard to the 
user.  Before any maintenance work is performed, disconnect power from the analyzer and turn off 
the gas supply.  Follow standard electrical safe work practices to prevent injuries. 

 

 

WARNING 

 

Electrical Hazard, Personal Injury and Equipment Damage: 

Do NOT 

perform maintenance on an energized or gas supplied analyzer. When 

performing maintenance on the unit, it is necessary to disconnect the power 
source from the unit, and turn off the gas supply lines (sample gas and zero 

gas). 

 

 

WARNING 

 

SYSTEM SAFETY: 

This analyzer is typed as permanently connected 

equipment and as such, must include a switch or circuit–breaker in the 

installation.  This switch must be supplied and installed by the customer (not 

provided by Servomex) must be suitably located and easily reached, and must 

be marked as the disconnecting device for the equipment. 

 

 

3.4.5 

Electrostatic Discharge 

 

 

WARNING 

 

Electrical Hazard, Personal Injury and Equipment Damage: 

The control of 

ESD is critical when performing maintenance on the Servomex SpectraScan 

Gas Analyzer.  To control ESD, users should wear ESD wrist straps and other 

grounding equipment between the analyzer and the skin. The wrist straps 

should be tested for ground continuity often.  Also, ground the analyzer 

(through the frame chassis or the control rack) to protect against: 

 

Damage to sensitive electronic components, such as circuit boards 

 

Electrostatic discharge 

 

User injuries from electrical shock when contact is made with the 
energized equipment.
