Power WiringAccess – First, ensure no power
source is connected to the inverter. If power
has been connected, verify that the Power
LED is OFF and then wait five minutes after
power down to proceed. After removing the
front housing cover, the two housing
partitions that cover the power and motor
wiring exits will be able to slide upward as
shown to the right. The upper cover is for
main power input wiring, and the lower one is
for the motor output wiring.
Notice the four wire exit slots in the housing
partition. This helps keep the power and
motor wiring (to the left) separated from the
signal-level logic or analog wiring (to the
right).
Remove the housing partitions and as shown
as set them aside in a secure place while
wiring. Be sure to replace them afterward.
Never operate the inverter with the partition
removed or the front housing cover removed.
The power input mains connect to the
terminals at the top of the inverter, and the
motor 3-phase leads connect to the lower row
of the terminals at the bottom of the inverter.
The upper row of the bottom terminals
connect to optional braking units or DC link
choke.
The following section in this chapter will
describe system design and guide you
through a step-by-step installation process.
After the section on wiring, this chapter will
show how to use the front panel keys to access
functions and edit parameters.
