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.
WA R N I N G
Interrupting the protective conductor inside or outside the MSD or disconnecting the
protective earth terminal (ground) creates a shock hazard for the operator and can
damage the instrument.
