3) Precautions on Wiring:
a） Input power R, S and T:
The cable connection at the input side of the servo driver has no phase
sequence requirement.
b） DC bus (+) and (-) terminals:
Note that the (+) and (-) terminals of DC bus have residual voltage right
after power-on. It needs to wait until the CHARGE indictor is OFF and
make sure that the voltage is less than 36V prior to wiring connection.
Otherwise there may be danger of electric shock.
When selecting external brake unit for the driver of above IS300T07
(inculded), the poles of (+) and (-) shall not be connected reversely, or it
