Installation Guide
ASTT30R - WIRING INSTRUCTIONS 
DO YOU STILL HAVE QUESTIONS?
Start by unscrewing each terminal. For this assembly, the use of Y-terminals is not neces-
sary. The terminals inside this connector work best with stripped wire and are far enough 
away from eachother to prevent any possibility of electrical arcing.
First, install the black and white wires into their respecve terminals, making sure they are 
secured ghtly. The green wire needs to be able to come slightly over the black wire at an 
angle. If the angle is too harsh, the copper wire could potenally break apart. So be sure to 
have the green wire come in as direct as possible. Then secure it ghtly. 
This connector works best with ST and SO 10/3 cable. The O ring (strain relief) can stay in 
its original layout. If it is a lile difficult to get the cable through this ring, you can warm it 
up a lile bit with a hair dryer or add non-flammable lubricant. 
Also, be sure to have the handle installed so it lines up behind the tab on the top of the 
plug. If it goes in front of that tab, it becomes useless.
