Ÿ
In order to prevent the high voltage and high current input into the power
supply circuit and damage the rectifier part, it is necessary to connect the
AC reactor on the input side, and also improve the power factor of the
input side.
Ÿ
Do not use the main circuit power ON/OFF method to control the
operation and stop of the inverter. The drive's operation and stop should
be controlled using the RUN and STOP keys on the keypad panel or the
control loop terminals. If the main power ON/OFF method must be used
to control the operation of the inverter, it can only be performed once per
hour.
Ÿ
A circuit breaker is required between the three-phase AC input power
supply and the main circuit terminals (R, S and T). It is better to connect a
magnetic contactor (MC) in series to cut off the power supply when the
inverter protection function is activated (the R-C surge absorber is
required at both ends of the electromagnetic contactor).
Ÿ
To reduce the interference of the inverter to surrounding equipment, the
noise filter can be connected to the input side.
Ÿ
If the inverter is equipped with an earth leakage circuit breaker as a
leakage fault protection, in order to prevent the leakage circuit breaker
from malfunctioning, please select a sensitivity current of 200 mA or
more and an operation time of 0.1 second or longer.
Ÿ
Do not connect the three-phase power supply to the single-phase power
supply.
