Power Wiring Access - Hitachi WJ200 Series Instruction Manual

Power Wiring Access – 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 terminal cover and front
housing cover, the housing partitions that cover the power and motor wiring exits will
be able to slide upward as shown below.
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 partition 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 and motor 3-phase wiring connect to the lower row of the terminals.
The upper row of power 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.
