C.Brake resistor terminals of BR+ BR-
The brake resistor terminal is effective only for the inverte r of 15kW or below and has a built-in brake
unit. Select the recommended resistor w ith the cable length of less than 5m, otherwise the inverter may
burn or be damaged.
D. Inverter output U, V and W:
Inverter output terminals cannot connect to capacitors or surge snub devices, otherwise the inverter may
be in protective status or damaged.
If the cables between the motor and the inverter are too long, electrical resona nce may occur due to the
distributed capacitance, which may result in damaging the motor insulation or big leakage current, so if
the cable length is longer than 100m, AC reactor must be installed.
E. Grounding Terminal :
Grounding Terminal must be connected to earth reliably and the grounding resistance shall be less than
Ω
5 , otherwise the equipment may work abnormally or be damaged. Do not sha re the PE and neutral line
of the mains supply.

3 ） N ote s o n C on t rol Te r m in al s:
A) Analog input terminal:
Since the weak analog voltage signal is easily disturbed by external disturbance source, shielded cable
shal l be used and the c able shall be as short as possible and the length shall not exceed 20m, as shown in
the figure 3-6:
Less than 20m

B) Digital input termi nal:
The inverter judges the ON/OFF status of these terminal s by receiving the digital signal. Hence, all the
external contactors are those with high reliability of weak signal conduction.
If the open collector is employed to provide ON/OFF signal for the inverte r digital input terminal, then
it shall be considered that there is error operation caused by power supply interference.
It is recommended to use contact control mode.
C) Digital Output terminal:
When digital output terminal drives a relay, the coil of the relay shall be installed a snubbing diode,
othe rwise the DC 24V power supply may be damaged.
