Connecting the Ground Cable
Connect the ground cable (yellow/green) between the ground terminal of the STP pump
and the ground terminal of the STP control unit.
When the resistance between the ground terminals is lower than 0.1 ohms, it is not
necessary to connect the ground cable after installing the STP pump and the STP
control unit.
◇
When the resistance betw een the ground terminals is over 0.1 ohms, alw ays
