Changing The Control Logic - Mitsubishi Electric FR-E720-600 Instruction Manual

2.3.2

Changing the control logic

NOTE
Fully make sure that the front cover has been reinstalled securely.
The capacity plate is placed on the front cover and the rating plate is on the inverter. Since these plates have the
same serial numbers, always reinstall the removed cover onto the original inverter.
The sink-source logic change-over jumper connector must be fitted in only one of those positions. If it is fitted in both
positions at the same time, the inverter may be damaged.
Control circuit specifications
The input signals are set to sink logic (SINK) when shipped from the
factory.
To change the control logic, the jumper connector above the control
terminal must be moved to the other position.
To change to source logic, change the jumper connector in the sink
logic (SINK) position to source logic (SOURCE) position using
tweezers, a pair of long-nose pliers etc. Change the jumper
connector position before switching power on.
