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 
right 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 terminal or circuit compo-
nent. 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.
