 Due to the inherent operating principle and construction of circuit breakers,
independent of the manufacturer, hot ionized gases may escape from the
breaker enclosure in case of a short-circuit. To ensure safe use, special attention
must be paid to the installation and placement of the breakers. Follow the
manufacturer's instructions.
It is necessary to install the electromagnetic contactor in the input side to control the switching on and
off safety of the main circuit. It can switch off the input power supply when a system fault occurs.
D.5.1 AC 3PH 380V(-15%)–440V(+10%)
Contactor rated working
current (A)
Note: The specifications can be adjusted according to the actual working, but they cannot be less
than the designated values.
D.6 Reactors
High current in the input power circuit may cause damage to the rectifying components. It is
appropriate to use AC reactor in the input side for the avoidance of high-voltage input of the power
supply and improvement of the power factors.
If the distance between the inverter and the motor is longer than 50m, frequent overcurrent protection
may occur to the inverter because of high leakage current caused by parasitic capacitance effects
from the long cables to the ground. In order to avoid the damage of the motor insulation, it is
necessary to add reactor compensation.
