Lambda EMS 7.5-75 - Specifications

5. Use extreme caution when connecting the high voltage output cable including the
separate ground connecting the supply to the load.
6. Ensure all load capacitors are completely discharged prior to connection. Never handle
the output cable when the power supply is operating.
7. Always replace fuses with the same type and Volt/Amp ratings.
8. Never attempt to operate the power supply in any manner not described in this manual.
9. Never remove DANGER and WARNING labels from the power supply, and replace lost
or damaged labels immediately.
10. The power supply should only be serviced by Lambda EMI factory qualified personnel.
1.3 SPECIFICATIONS
All performance specifications, unless otherwise stated, are defined in the local programming
configuration. Ripple, programming speed, transient response and stability are optimized
with the power supply so configured.
