Are the control terminal screws tightened to their specified
torques?
p.19
Is the total cable length of all control wiring < 165ft
(100m)?
p.33
Is the total length of safety wiring < 100ft (30m)?
Miscellaneous
Are optional cards connected correctly?
Is there any debris left inside the inverter?
Are any cables contacting adjacent terminals, creating a
potential short circuit risk?
-
Are the control terminal connections separated from the
power terminal connections?
-
Have the capacitors been replaced if they have been in use
for > 2 years?
-
Have the fans been replaced if they have been in use for >
3 years?
-
Has a fuse been installed for the power source?
Are the connections to the motor separated from other
connections?

STP (Shielded Twisted Pair) cable has a highly conductive, shielded screen around twisted cable pairs.
STP cables protect conductors from electromagnetic interference.
2.4 Test Run
After the post-installation checklist has been completed, follow the instructions below to test the
inverter.
1 Turn on the power supply to the inverter. Ensure that the keypad display light is on.
2 Select the command source.
3 Set a frequency reference, and then check the following:
• If V1 is selected as the frequency reference source, does the reference change according to
the input voltage at VR?
• If V2 is selected as the frequency reference source, is the voltage/current selector switch
(SW2) set to voltage, and does the reference change according to the input voltage?
