Single-phase connection:
Connect the earth and other two wires as shown
in example ”1AC” in the figure.
For the W645 and W662, special circuit breaker
considerations must be made. The following gui-
delines will assist you in selecting an appropriate
circuit breaker.
W645:
Select a 25 Amp circuit breaker capable of main-
taining at 60 Amperes for 8 seconds.
W662:
Select a 30 Amp circuit breaker capable of main-
taining at 70 Amperes for 7 seconds.
Three-phase connection:
Connect the earth and the three phases as
shown in example ”3AC” in the figure.
When the installation is completed, check:
• thatthedrumisempty.
• thatthemachineoperatesbyturningonthe
mains switch, starting the machine and using
RAPID ADVANCE to reach the spin cycle (see
operations manual).
IMPORTANT
When making power supply connections to
machines rated 208-240V AC, do not
connect any phase measuring in excess of
125 V AC (with respect to earth ground) to
the L1 or L2 terminals on the connection
block. So-called "stinger legs" must be
connected to the "L3" terminal, which does
not feed power to the control circuits of the
machine.
On three-phase models (except SU677),
check that the drum rotates in the direction
indicated on the machine while in extrac-
tion. If the direction is incorrect, reverse
two of the power line phases to correct the
rotation direction, while observing the note
above.
