Table 1.
 3
rd
column of table 1 gives maximum resulting current at maximum power rating of
3 W.
With use of fuse connections (far left and right connections):
 Limit resulting current by activating appropriately high resistor values and / or
appropriately low applied voltage to limit resulting current below nominal fuse rating
of 400 mA .
 At higher currents the micro-fuse may trigger and has to be changed for further use
of the decade. In this refer to chapter 5. “change of fuse”.
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 personal injury particularly in the case of “no activated resister” or “use of
connections without fuse”, i.e. right black and middle red connections.
