Correcting Phase Polarity (G0601

Only)

this subsection is only provided for troubleshoot-
ing.  if  you  discover  during  the  test  run  that  the
machine will not operate, or that the impeller spins
backward,  the  power  connections  may  be  wired
out-of-phase.  Without  the  proper  test  equipment
to determine the polarity of the power source legs,
wiring  machinery  to  3-phase  power  may  require
trial-and-error. Correcting phase polarity is simply
a  matter  of  reversing  the  positions  where  two  of
the  incoming  power  source  wires  are  connected
inside the control box.

NOTICE

if this machine is wired out-of-phase, the

motor and impeller will spin in the wrong

direction. The efficiency of the dust col-

lector will be greatly reduced and will not

provide the rated CfM. You must make

sure the motor is spinning in the correct

direction before placing the machine into

full operation. Perform Step 10 of the test

run on Page 32 to make sure the machine

is correctly wired.

To correct phase polarity:

1. disConneCt MAChine FroM poWer!

2. open the control box and swap the connec-

tions of any two incoming hot wires from the
power source (see

figure 6).

3. secure the control box cover, then re-connect

the machine to power.

4. perform Step 10 of the test run on Page 32

to confirm that the power connections are
correct.
