t appended when sales.
2. For the related knowledge on regenerative voltage, please refer to P.30 in Chapter 4.
3. P and N are the positive and negative terminals of the internal DC voltage of the inverter. In order to
strengthen the braking capability during deceleration, it is suggested to purchase the option of
‘
brake
unit
’
which is mounted between the terminals P and N. The
‘
brake unit
’
can effectively dissipate the
feedback energy from the motor to the inverter when decelerating. In case there is any problem on
purchasing of the
‘
brake unit
’
, please feel free to contact us.
4. For safety and reduce noise, grounding terminals of inverter must to be good grounded. To avoid electric
shocks and fire accident, external metal wire of electrical equipment should be short and thick and it
should be connected to the special grounding terminals of inverter. If many of the inverters are placed
together, all inverters must be connected to the common ground. Please refer to the following picture and
determine not formed circuit between grounding terminal.
