Position of terminals
Warning
To avoid the risk of electric shock or fire,
make sure that the power supply has been
cut off before connecting the equipment.
To avoid live voltage on the cabinet, make
sure the earth terminal is reliably
grounded.
Caution
To avoid arcing and fire, tighten all
terminals with the specified torque.
For distances (pump to inverter) exceeding
30 m, we recommend a reactor with
matching current ratings.
