◆
Terminals (+) and (-) of DC bus have residual voltage after the AC drive is switched off. After
indicator CHARGE goes off, wait at least 10 minutes before touching the equipment Otherwise, you
may get electric shock.
◆
Do not connect the braking resistor directly to the DC bus. Otherwise, it may damage the AC drive
and even cause fire.

◆
The cable length of the braking resistor shall be less than 5 m. Otherwise, it may damage the AC
drive.
