ELECTRICAL CONNECTION
Multiple Single-Phase Machines in Line
When installing multiple single-phase washers into an existing 3-phase power supply, alternating the phases used as the hot leg is
recommended to evenly distribute power on the system. See illustration.

Instructions For Grounding
This appliance must be connected to an equipment grounding conductor that must run with the circuit conductors and connected to
the aluminum ground lug inside the rear electric panel.
Connect the terminal strip and check that the connections correspond to the operating voltage. Fit a 300 mA, type A, immediate
response differential protection.
The machine must be grounded. See the illustration on the previous page.
Equipotential Bonding
In addition to the equipment-grounding conductor discussed earlier that runs with the circuit conductor's and is connected to the
equipment grounding terminal, all washers or appliances in the vicinity must be permanently interconnected with a equipotential
bonding conductor.
The external connection points marked on the back of the washer serve for this purpose. See illustration below.
The cross-sectional area of the conductor must be at least electrically equivalent to the cross-sectional area of the copper conductor
used to power the washer.
