Mounting FLEXmax Charge Controller
The GSLC enclosure accommodates up to two FLEXmax charge controllers and a HUB 
Communications Manager. 
NOTE
: The following instructions are for the FLEXmax 60 or FLEXmax 80 only. The FLEXmax Extreme 
charge controller connects directly to the wall and does not need additional brackets. 
Figure 24  Mounting the Charge Controller to the GSLC Enclosure  
To mount the FLEXmax Charge 
controller to the side of the GSLC 
enclosure: 
1.  Align the brackets to the 
mounting holes and secure the 
brackets to the sides of the 
enclosure with the hardware 
provided with the brackets. 
2.  Note the location of knockouts on 
both the charge controller and the 
GSLC. (See page 16.) The holes 
will align when the brackets are 
used. Remove knockouts if 
necessary and insert bushings.  
3.  Align the charge controller with 
the center hole on each bracket 
and secure with the hardware 
provided with the brackets.
