4.3.3 Mounting the Sunny Boy
Use the following procedure to mount the Sunny Boy:
1. Carefully lift the Sunny Boy onto the wall-mounting bracket. Hook the Sunny Boy using the
enclosure opening in the back plate into the wall bracket (see # 1 in Figure above).
2. Inspect the Sunny Boy from both sides to ensure that it sits centered on the wall bracket.
3. Attach the Sunny Boy to the mounting bracket with the two M6 screws and washers provided
through holes next to the fan outputs on both sides of the Sunny Boy (see # 2 in Figure above).
The teeth of the washers should face towards the wall in order to ensure proper grounding.
Tighten the screws to a torque of 44 in-lb (5 Nm).
4. Close the fan outputs with the handle covers (see # 3 in Figure above) provided in the
accessories kit. They are required to adequately prevent insects entering the unit.
5. Carefully verify that the Sunny Boy is firmly mounted in place.
WARNING!
The Sunny Boy weighs up to 147 lb. (67 kg). To avoid injury, be sure to use proper lifting
techniques and secure the help of someone to assist in the unpacking and installation of
the inverter.
Should the handle covers break, new handle covers can be ordered from SMA America.
