CAUTION: 

The module contains devices sensitive 

to Electrostatic Discharge (ESD). When working on the 
module with the front panel removed, work surfaces 
and personnel must be properly grounded or 
equipment damage may result.

!

CAUTION:

 Removal of enclosure panels exposes 

circuitry which may cause electrical shock which can 
result in injury or death.

!

DANGER:

 Contact with instrument terminals may 

cause electrical shock which can result in injury or death.

!

DANGER:

 Contact with this circuitry may cause 

electrical shock that can result in injury or death.

ATTENTION:

 

Le module contient des pièces 

sensibles aux décharges électrostatiques. Quand on 
travaille sur le module avec les panneaux avant ou du 
dessus enlevés, toutes les surfaces et le personnel 
doivent être mis à la terre convenablement pour éviter 
les dommages à l’équipement.

ATTENTION:

 Le retrait des panneaux du boîtier 

expose le circuit qui peut causer des chocos électriques 
pouvant entraîner des blessures ou la mort.
