N300-P INSTRUCTION MANUAL
Cautions for EMC (Electromagnetic Compatibility)
To safety the EMC directive and to comply with standard, follows the checklist below.
This equipment should be installed, adjusted, and serviced by qualified personal familiar with
construction and operation of the equipment and the hazards involved. Failure to observe
this precaution could result in bodily injury.
1. The power supply to N300-P inverter must meet these specifications
a. Voltage fluctuation
b. Voltage imbalance
c. Frequency variation
d. Voltage distortion THD = 10% or less.
2. Installation measure :
a. Use a filter designed for N300-P inverter
3. Wiring
a. Shielded wire (screened cable) is required for motor wiring, and the length must be less
than 20 meters.
b. The carrier frequency setting must be less than 3kHz to satisfy EMC requirements.
c. Separate the main circuit from the signal/process circuit wiring.
d. In case of remote operating with connector cable, the inverter does not conform to EMC.
4. Environmental conditions - when using a filter, follow these guidelines:
a. Ambient air temperature : -10 - +50 .
b. Humidity : 20 to 90% RH(non-condensing)
c. Vibration : 5.9 m/sec (0.6 G) 10 - 55Hz ( N300- 055 - 300LFP / 055 - 300HFP)
d. Location : 1000meters of less altitude, indoors (no corrosive gas or dust)
10% or less.
3% or less.
4% or less.
