Table 1.
1 MΩ
 3 column of table 1 gives maximum resulting current at maximum power rating of
1W.
d) Maximum Operational Voltage
This decade is approved for a maximum voltage of 250 V AC rms / DC.
 DO NOT APPLY any higher voltage than 250 V AC rms / DC to the connections of the
decade!
 DO NOT APPLY ANY voltage to the connections of the decade without any activated
resistor! This may lead to damages and even total destruction of the decade as well as
to perso al i jur parti ularl i the ase of no a ti ated resister or use of
connections without fuse , i.e. right black and middle red connections.
 In relation to the activated resistor value the maximum allowed operational
rd
voltage V may possibly be significantly lower than the maximum voltage of 250 VAC
rms / DC due to the maximum power rating of 3W!
 Up to a maximum activated resistor value of 20kΩ the applied voltage must be lower
than the maximum voltage of 250 V to avoid overloading of the resistors.
 Limit voltage to be applied according values given in table 1.
