Connection - Main Array Input
1.
Terminate cables with MC4 Connectors. Connect the cable to the Isolator.
Ensure Polarity on the MC4 connections is correct. TEST the polarity at the
MC4 connectors
BEFORE CONNECTION TO THE CONTROLLER
. Ensure to
connect the earth from the controller to the earth point from the main
array frame within the Isolator. Earth from controller and Array must be
connected to house ground point.
See Wiring Diagram - Controller - Figure 3
2.
Test voltage from array. Confirm correct for controller model and cylinder
element.
3.
Connect MC4 Connectors to controller input only when ready to
commission - See Commissioning Start up pg 19.
Ensure polarity at the MC4 connectors is correct before proceeding
further.
TURN ISOLATOR ON AND TEST CORRECT POLARITY TO CONFIRM
BEFORE PROCEEDING.
IT IS IMPORTANT TO ENSURE THAT THE SUPPLY FROM THE MAIN ARRAY IS
TERMINATED POLLARITY CORRECT AND MUST BE CHECKED BEFORE
CONNECTION!!
THE CONTROLLER WILL BE DESTROYED IF REVERSE POLARITY CONNECTED!!
Incorrect polarity will void the warranty
