Mounting the Sunny Boy
Figure 3-9 Mounting the Sunny Boy
Use the following procedure to mount the Sunny Boy:
1. Carefully lift the Sunny Boy onto the mounting bracket. Hook the Sunny Boy
using the enclosure opening in the back plate into the wall bracket (see #1 in
Figure 3-9).
WARNING: The Sunny Boy weighs 88 lb. (40 kg). To
avoid injury, be sure to use proper lifting techniques
and secure the help of someone to assist in the unpack-
ing and installation of the inverter.
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 # 2in Figure 3-9). 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. Snap the left and right handle covers, provided in the accessories kit, into the
Sunny Boy ( see # 3in Figure 3-9). Look for the L & R on the inside of the fins.
They are required to adequately prevent insects entering the unit.
Note: Should the handle covers break, new handle covers
can be ordered from SMA America.
5. Carefully verify that the Sunny Boy is firmly mounted in place.
