■   Communication between master and slave unit

A)    The unit can only be powered on and commissioned 

after the address numbers are configured. 

B)  Control (Communication) Wire Connection

A) conductor (WTC pair with cross section 

area  of  at  least  0.5mm2  or  20AWG);  B) 

insulator; C) Screen layer (twisted WTC with 

a screening factor no less than 95%) ; D) 

Outer jacket (PVC);

NOTE: 
BETTER  CHOOSE  NETWORK  CABLES  WITH 
A  TENSER  SHIELDING  LAYER AND  SMALLER 
TWISTING DISTANCE. 
PLEASE REFER TO THE UL2547 OR UL2791 WIRE 
SPECIFICATION. 
THE  CONTROL  WIRE  MUST  NOT  BE  LONGER 
THAN 1000 METERS. 
THE CONTROL WIRE MUST BE AT LEAST 20CM 
AWAY FROM MAJOR CURRENT WIRE.
