Note:   

1. It is necessary to make REF and SG terminals short-circuited for PH-300T if 2-wire 

 

distribution system is applied (with a built-in jumper between them). 

 

2. The black wire would be forbidden if 8-26-8 is used as 2-wire distribution. 

 

3. It is necessary to apply our coaxial 4-core wire: 7202-F94009-BK.
