1.2.8 The Derating of the AC Drive
Different power grade frequency converter has its default carrier frequency,
when to run at a higher carrier.frequency, the AC Drive must to reduce the
amount when running.
1.2.9 Prohibition of Three-Phase Input Change into Two-Phase Input
Do not change the three-phase input of the AC drive into two-phase input.
Otherwise, a fault will result or the AC drive will be damaged.
1.2.10 Surge Suppressor
The AC drive has a built-in over-voltage, over-current device for suppressing the
surge voltage generated when the inductive loads around the AC drive are
switched on or off. If the inductive loads generate a very high surge voltage, use
a surge suppressor for the inductive load to prolong the service life of the AC
drive.
1.2.11 Ambient Temperature and De-rating
The normal use of the frequency converter ambient temperature is -10℃ ~40℃ .
Temperature exceeds 40℃ ,the equipment need to reduce the amount of use.
The ambient temperature of each increase is reduced by 1.5%,the maximum
use of the ambient temperature is 50℃ .
1.2.12 Altitude and De-rating
In places where the altitude is above 1000m and the cooling effect reduces due
to thin air, it is necessary to de-rate the AC drive. Contact our company for
technical support.
1.2.13 Disposal
The electrolytic capacitors, plastic parts and other devices may explode when
they are burnt. Poisonous gas is generated when they are burnt. Treat them as
ordinary industrial waste according to relevant national laws and regulations.
