3.3 Installing Fiber Cables (Only for IT7930P-350-180) 
IT7930P-350-180 model is composed of two 15kVA parallel machines. In order 
to avoid damage to the fiber  cords connected in parallel with the  master and 
slave during transportation, the fiber cords are not installed before delivery. After 
receiving  the  instrument,  users  need  to  install  the  yellow  fiber  cable  by 
themselves. 
 
 
⚫  Before connecting the cables, ensure that the instrument power switch is off 
and the main switch of the AC power input (distribution box) is off. 
⚫  Fiber optic cables cannot be flexed or folded. When the cable is too long 
and needs to be arranged, gently wrap the cable in a circle and gently tie it.

and slave by fiber cords.
