INSTALLATION AND WIRING
21
Note:1. Make sure that the front cover has been installed securely.
2. The front cover has a capacity plate and the inverter a rating plate on it.
Since these plates have the same serial numbers, always reinstall the
removed cover to the inverter from where it was removed.
3. Always install the sink-source logic changing connector in either of the
positions. If two connectors are installed in these positions at the same time,
the inverter may be damaged.
2) Sink logic type
!
In this logic, a signal switches on when a current flows out of the corresponding
signal input terminal.
Terminal SD is common to the contact input signals.
Terminal SE is common to the open collector output signals.
