Power connection
Unscrew the four plastic bolts on the front panel of the electric box and lift the cover (Fig. 2).
When opening the electric box front panel, do not pull on the cable bunch connecting it to the box
itself. Do not pull the leads as they might break (refer to the Fig. 1).
MAKE SURE THAT THE POWER SUPPLY IS OFF AND THAT NOBODY CAN SWITCH IT
ON DURING THIS OPERATION.
Connect the power supply line to the electric control box. Use terminals Nos. 1 and 3 if the watermaker is
single-
phase
type (refer to the id plate on the watermaker motors and main frame) and terminals Nos. 1, 2 and 3 for the
three-phase
systems (fig.3).
Close the electric box cover by tightening well the four bolts on its front (Fig. 2).
Connect the watermaker steel structure to the ground using the grounding lug identified by the appropriate symbol
(the point is on the steel structure or in the control panel).
Power on the supply line and check that the display is illuminated.
