3.Third-level access - First, ensure no power source of any kind is connected to the inverter. If power has been connected, wait five minutes after powerdown and verify the Power LED is off to proceed. Then locate the recessed retention screw on the left side main front panel (it is along the left hinge area on some models, or behind the first access door on others). Use a small

screwdriver (Regular or Phillips) to loosen the screw. Swing the door around to the left to reveal the internal components of the drive. The two-level tiered 12-position terminal block accepts wires for the power input and wires to the motor.

Notice the housing partition that lifts out to allow full access to the terminals for wiring as shown. Never operate the inverter drive with the partition removed or the full access door opened.

The alarm circuit connections are accessible on the 3-position connector near the modular connector on the rear of the main panel door. The nearby relay provides both normally- open and normally-closed logic for interface to an external alarm. The alarm circuit may carry hazardous live voltages even when the main power to the inverter is off. So, never

directly touch any component on the circuit board in the panel door. A notch in the removable partition serves as the exit path for alarm circuit wiring.

The following sections 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.
