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