Power Wiring Access – First, ensure no power

 

 

source of any kind is connected to the inverter.

 

 

If power has been connected, wait five

 

 

minutes after power down and verify the

 

 

Power LED is OFF to proceed. After removing

 

 

the front housing cover, the two housing

 

 

partitions that covers the power wiring exit

 

 

will be able to slide upward as shown to the

 

MountingInverter installationand

 

partition. This helps keep the wiring (to the

 

 

right. One at the upper side is for main power

 

 

input terminals, and the one at the lower side

 

 

is for the motor output side power terminals.

 

 

Notice the four wire exit slots in the housing

 

 

left) separate from signal-level logic or analog

 

 

 

 

wiring (to the right).

 

 

Remove the housing partitions and as shown

Power input terminals

 

as set it aside in a secure place while wiring.

 

 

Never operate the inverter drive with the

 

 

partiti on removed or the front housing

 

 

cover removed.

 

 

The power input wiring connect to the upper

 

 

terminals, and motor 3-phase wiring connect

 

 

to the lower row of the lower portion

 

 

terminals. The upper row of the lower part

 

 

terminals connect to optional braking units.

 

 

The following section in this chapter will

 

 

describe the 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.
