Remarks: the bolts of input line and output line of power source of controller must
be tightened according to the required torque. Because binding post and circuit board
adopt electrical welding process, excessively high tightening torque will damage binding
post of controller and lead to the
breakdown
of binding post.
!
Warning:
●
Input line and output line of power source must be
same
with the symbols
on controller. Red line on positive pole of power source is connected to “+” of
controller. Black line on negative pole of power source is connected to “-” of
controller. The output end of controller is connected to phase line of
DC
motor
. “Y” end is connected to yellow line of
DC motor
. “G” end is connected
to green line of
DC motor
. “B” end is connected to blue line of
DC motor
.
Otherwise, controller will be damaged or
cannot
start
properly
.
●
Before
start
the above work, disconnect
air circuit breaker
and power source
or take battery down.
