All installation specification described at the previous chapters named INSTALLATION 
AND STARTUP, INSTALLATION MODES and SPECIFICATIONS. 

Note that with the instrument powered on, the terminals could be dangerous to touching 

and cover opening actions or elements removal may allow accessing dangerous parts. This 
instrument is factory-shipped at proper operation  condition.
