Post-Installation Checklist
After completing the installation, check the items in the following table to make sure that the
inverter has been safely and correctly installed.
Installation
Location/Power
I/O Verification
Is the installation location appropriate?
Does the environment meet the inverter’s operating
conditions?
Does the power source match the inverter’s rated input?
Is the inverter’s rated output sufficient to supply the
equipment?
(Degraded performance will result in certain circumstances.
Power Terminal
Wiring
Is a circuit breaker installed on the input side of the
inverter?
Is the circuit breaker correctly rated?
Are the power source cables correctly connected to the
R/S/T terminals of the inverter?
(Caution: connecting the power source to the U/V/W
terminals may damage the inverter.)
Are the motor output cables connected in the correct phase
rotation (U/V/W)?
(Caution: motors will rotate in reverse direction if three
phase cables are not wired in the correct rotation.)
Are the cables used in the power terminal connections
correctly rated?
Is the inverter grounded correctly?
Are the power terminal screws and the ground terminal
screws tightened to their specified torques?
Are the overload protection circuits installed correctly on
the motors (if multiple motors are run using one inverter)?
Is the inverter separated from the power source by a
magnetic contactor (if a braking resistor is in use)?
Are advanced-phase capacitors, surge protection and
electromagnetic interference filters installed correctly?
(These devices MUST not be installed on the output side of
the inverter.)
Control
Terminal Wiring
Are STP (shielded twisted pair) cables used for control
terminal wiring?
