SD1 Series Inverters Product Overview
-6-
When the altitude exceeds 1000m, derate by 1% for every increase of 100m.
4. Whether the ambient humidity is higher than 90% or condensation occurs. If yes, take
extra protective measures.
5. Whether there is direct sunlight or biological invasion in the application environment. If
yes, take extra protective measures.
6. Whether there is dust or inflammable and explosive gas in the application environment.
If yes, take extra protective measures.
2.1.4 Installation confirmation
Check the following items after the installation of the inverter is complete.
1. Whether the input power cables, and motor cables meet the current-carrying capacity
requirements of the actual load.
2. Whether the peripheral accessories are correctly selected and properly installed, and
whether the installation cables meet the current-carrying capacity requirements of the
accessories, including the input reactor, input filter, output reactor, output filter, DC
reactor, braking unit, and braking resistor.
3. Whether the inverter is installed on non-flammable materials, and whether its
heat-emitting accessories (such as reactor and braking resistor) are kept away from
inflammable materials.
4. Whether all the control cables are wired separately from power cables, and whether
electromagnetic compatibility (EMC) specification requirements are taken into full
account during the wiring.
5.
Whether all the grounding systems are properly grounded according to the
requirements of the inverter.
6. Whether all the installation spacings of the inverter meet the requirements stated in the
manual.
7. Whether the installation of the inverter meets the requirements stated in the manual.
8. Check that the external connection terminals are tightly fastened and whether the
torque meets the requirements.
9. Whether screws, cables, or other conductive items drop into the inverter. If yes, take
them out.
2.1.5 Basic commissioning
Complete the basic commissioning as follows before using the inverter.
1. Perform autotuning if required. Remove the motor load, if possible, to perform dynamic
parameter autotuning; and if the load cannot be removed, you can perform static
autotuning.
2. Adjust the ACC/DEC time according to the actual operation conditions of the load.
