Electric device has option for small systems (S) and large systems (L). Small system option is typical
for vehicle applications and large system option is standard in marine applications because of the
marine regulations. Complete system should be looked when choosing the option as for example
vehicle system with many devices could also need the L-option to keep the isolation resistance or
Y-capacitors at reasonable level. In large and small system options, there are difference in the
isolation measurement resistance, DC-link discharge resistor and Y-capacitor values as shown in
the gure and table below.
