Selection Charts
The selection charts state the maximum capacitance per voltage level which can be discharged with each resistor module:
1. Select the line of your operating voltage. Mind that in detuned systems, the actual voltage at the capacitor is higher
than the rated mains voltage.
2. Look for the column with the capacitance which is closest to your capacitor. Look up BLACK figures if you want
to discharge below 50 V within no more than 60 seconds. Look up BLUE figures if you want a discharge below 75 V
within 3 minutes. Go for GREY figures if 5 min discharge is sufficient.
3. Determine the resistor module to be ordered in the head of the column.
