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 operation, but they are recommended for<br />
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 />
The isolation contactor "K1" is optional, and is not necessary<br />
for the SSW-03 Plus operation. However due to<br />
protection and safety reasons it's recommended. In case<br />
of maintenance the input fuses must be removed for a<br />
complete disconnection of the SSW-03 Plus from the<br />
line.<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 />
