Refer to p.986~ for general precautions, and to the “Operation Guide” or “SUNX website”
(http://www.sunx.com) for details pertaining to operating instructions for the amplifi er.
Never use this product as a sensing device

The FX-100 series does not use the horizontal 
connectors that are used with the FX-300 / FX-400 
series. Please note that horizontal connection cannot be 
performed using a connector attached cable. In addition, 
the optical communication function is not equipped on 
the FX-100 series, so it is unable to perform interference 
prevention for use with the FX-300 / FX-400 series. 
If using the FX-100 series together with the FX-300 / 
FX-400 series side-by-side, please set the same models 
together in groups.
