Obs.: It's necessary to use normal fuses or breaker to protect
the installation. Ultra-Fast fuses are not necessary for
the SSW-03 operation, but they are recommended for
SCR protection.
The transformer "T" is optional and must be utilized
when the line voltage is different than the electronics
and fan voltage.
The isolation contactor "K1" is optional, and is not nec-
essary for the SSW-03 Plus operation. However due to
protection and safety reasons it's recommended. In case
of maintenance the input fuses must be removed for a
complete disconnection of the SSW-03 Plus from the
line.
For the integral motor protection it's recommended to
install one or more thermostats in the motor. If the ther-
mostat is not used, the external input error (DI3) from
SSW-03 Plus must be connected to +Vdc.
