Earth (ground) Connection
We recommend that you fit a separate earth (ground) conductor to the TV903
Pumping System. 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.

The controller must be supplied with a voltage of 48 Vdc (± 10 %) according to
the drawing (use 2 pins for each pole).
Input current during Normal Operation: 6.5 A
