Power configurations

Electrical power for the MSD must be single-phase. The neutral wire cannot be used for safety grounding. The ground wire should carry zero current except for ground-fault current or static electric discharge. The entire system should share an isolated, noise-free electrical ground. This system ground should be electrically separate from the ground for the rest of the building, back to the main ground for the facility. Power configurations are provided in Table 3.

WA R N I N G

 

Connecting an MSD to a power source which is not equipped with a protective earth

 

contact (ground) creates a shock hazard for the operator and can damage the

 

 

 

 

instrument.

 

 

 

 

 

 

 

 

 

Interrupting the protective conductor inside or outside the MSD or disconnecting the

WA R N I N G

 

protective earth terminal (ground) creates a shock hazard for the operator and can

 

 

 

 

damage the instrument.
