INSTALLATION<br />
The isolation contactor "K1" is optional, and is not necessary<br />
for the SSW-03 Plus operation. However due to protection<br />
and safety reasons it is recommended. In case of maintenance<br />
the input fuses must be removed for a complete disconnection<br />
of the SSW-03 Plus from the line.<br />
For the integral motor protection it is recommended to install<br />
one or more thermostats in the motor. If the thermostat is not<br />
used, the external input error (DI3) from SSW-03 Plus must<br />
be connected to +Vdc.<br />
NOTE!<br />
Contactor "K1" is necessary to protect the motor in case there<br />
is a phase failure, which is caused by damage in the SSW-03<br />
Plus power circuit.<br />
