2.3 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?
(Derating is applied in specific conditions. Refer to
11.8 Continuous Rated Current Derating on
page 315 for more details.)
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 input 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 order?
(Caution: motors will rotate in reverse direction if
the 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.)
