3 Installation and Wiring
3.1 Installation Condition
3.1.1 Use the Frequency Converter after Long-term Storage
If the storage time of the frequency converter is more than 1 year, then before installing and
using it, the capacitor in it must be re-applied with voltage.
Voltage
[%]
Time [h]
If the storage time is less than 1 year, no additional treatment is required.
If the storage time is 1-2 years, before use, reapply voltage to the capacitor for 1 hour and
use 100% voltage.
If the storage time is 2-3 years, before use, reapply voltage to the capacitor for 2 hours.
First, use 25% voltage for 0.5 hour, next 50% voltage for 0.5 hour, then 75% voltage for
0.5 hour, and 100% voltage for 0.5 hour.
If the storage time is more than 3 years, before use, reapply voltage to the capacitor for 8
hours. First, use 25% voltage for 2 hours, next 50% voltage for 2 hours, then 75% voltage
for 2 hours, and 100% voltage for 2 hours.
3.1.2 Installation Environment
1) Ambient temperature: The ambient temperature has a great influence on the service life of
the frequency converter. The operating environment temperature of the frequency converter
should not be out of the allowable temperature range (-10
℃
- 50
℃
).
2) To install the frequency converter on the surface of a flame-retardant base, please refer to
the chapter related to reserve enough space for heat dissipation. When the frequency
converter works, it is likely to generate a lot of heat. And install it vertically on the mounting
base with screws.
3) Please install the frequency converter in a place with small vibration. The vibration should
