Obs.: It's necessary to use normal fuses or breaker to protect<br />
the installation. Ultra-Fast fuses are not necessary for<br />
the SSW-03 Plus operation, but they are recommended<br />
for SCR protection.<br />
The transformer "T" is optional and must be utilized<br />
when the line voltage is different than the electronics<br />
and fan voltage.<br />
For the integral motor protection it's recommended to<br />
install one or more thermostats in the motor. If the thermostat<br />
is not used, the external input error (DI3) from<br />
SSW-03 Plus must be connected to +Vdc.<br />
NOTE!<br />
A contactor in the mains input (see 9.4) is necessary to protect<br />
the motor in case there is a phase failure which is caused<br />
by damage in the SSW-03 Plus power circuit with the application<br />
of the power isolation contactor.<br />
