Installing the Inverter
22
•
Power supply cables must be connected to the R, S, and T terminals.
Connecting power cables to other terminals will damage the inverter.
•
Use insulated ring lugs when connecting cables to the R/S/T and U/V/W
terminals.
•
The inverter’s power terminal connections can cause harmonics that may
interfere with other communication devices located near to the inverter. To
reduce interference, the installation of noise filters or line filters may be
required.
•
To avoid circuit interruption or damage to connected equipment, do not install
phase-advanced condensers, surge protection, or electronic noise filters on
the output side of the inverter.
•
To avoid circuit interruption or damage to connected equipment, do not install
magnetic contactors on the output side of the inverter.
Step 4 Control circuit connections
The illustrations below show the detailed layout of the control circuit connections
and the control board switches. Ensure that the control cables meet the required
specifications and refer to the detailed information provided below and
on page
before installing and connecting control circuits.
