Installation

1. Locate two threaded mounting studs and two mounting slots in the bottom left corner of the 

backbox (refer to backbox illustration below).

2. Position the Transformer Assembly with the bottom mounting brackets in the mounting slots 

and the top brackets on mounting studs, with cable assembly oriented to the top as illustrated 
below.

3. Secure the Transformer to the studs with the two supplied nuts.  Do not tighten one of the nuts 

until the next step.

4. Connect a wire from a solid earth ground to one of the Transformer mounting studs and tighten 

the nut.  This connection is necessary in order to provide proper lightning and transient 
protection for the panel.

5. Plug Transformer cable assembly into connector P1 which is located in the lower left side of 

the main circuit board.  Note that the Transformer cable connector is keyed to prevent incorrect 
connection.

6. Complete the installation by connecting the AC power wires to Hot, Neutral and Earth 

terminals of TB3 on the main circuit board.

7. If batteries are being used, connect the batteries (18 AH maximum) to connector P10 located to 

the bottom left of the main circuit board.

8. Apply power to the panel. 

BEFORE INSTALLING ANY MODULES OR CABLES, MAKE CERTAIN ALL POWER (AC AND DC) 
HAS BEEN REMOVED.
