Requirements
Control Wiring Terminal Block:
The Inverter ON/OFF terminals are used for connecting an
external ON/OFF switch. To use this feature, the jumper
must be removed. (See Radian manual for details.)
The AUX terminals can be used to start a generator
or to control external devices.
AUX terminals are also available on the charge
controller and the FLEXnet DC. (See the charge
controller or FNDC installation manuals for details.)
Mounting
WARNING: Fire/Explosion Hazard
Do not place combustible or flammable materials within 12 feet (3.7 m) of the equipment. This unit employs mechanical
relays and is not ignition-protected. Fumes or spills from flammable materials could be ignited by sparks.
WARNING: Personal Injury
Use safe lifting techniques and standard safety equipment when working with this equipment.
IMPORTANT:
Clearance and access requirements may vary by location. Maintaining a 36” (91.4 cm) clear space in front of the system
for access is recommended. Consult local electric code to confirm clearance and access requirements for the specific
location.

Radian Mounting:
1. Ensure the mounting surface is strong enough to handle 3 times the total weight of
all the components. Add a piece of plywood if necessary to strengthen the surface.
2. Attach the wall bracket to the surface centering the mounting holes on the sides
with the wall studs. Use all 6 mounting screws to secure the bracket.
3. Lift the inverter so that the inverter bracket is above the wall bracket.
4. Lower the Inverter into place so that the inverter bracket slips into the wall bracket.
