Earth (Ground) Connection

We recommend that you fit a separate earth (ground) conductor to
the TwisTorr 304 FS. Use a separate insulated green/yellow
conductor, and use a M5 x 10 screw and shake proof washer (fitted to
the earth hole on the pump) to secure the earth conductor to the
pump. The screw must be fixed with a 2 Nm torque.
The impedance between the pump-body and the earth connection
point must be < 0.1 Ω.
