The 115VIF-3 interface board is used to translate 115 VAC control signals – from crane and 
hoist operator pendant stations – to the 24 VDC logical input signals required by the SJ200 or 
SJ700 series of Hitachi inverters. 
 
The board provides optical isolation between the 115 VAC pendant voltages and the inverter 
control inputs. It also incorporates the necessary logic functions to perform application-specific 
crane and hoist functions, as described in a later section of this manual. 
 
Before using this product, please read this manual and the inverter manual, and be sure to follow all safety 
precautions noted therein. After unpacking the 115VIF-3 board, carefully inspect it for any defect or damage.
