SMA SB 3800-U - Manual (Page 21)

SB3800U-12:SE2006 SMA America 3-7
Note: The diameter of the holes you drill must match the hardware you
are using to mount the SB3800U. For example, if you are mounting the
SB3800U to a concrete wall, the hole diameter should be approximately
the same as the outside diameter of the concrete anchors you intend to
use. If you are mounting the SB3800U on a wall that has wooden studs
inside it, the hole diameter should be the correct size for the lag screws
you intend to use to mount the plate. If you are installing the SB3800U
outside, it is recommended that the lag screws be made of stainless steel,
and the diameter of the screws closely match the diameter of the holes
in the mounting plate. Make sure that the screws are long enough to
penetrate the wall to a depth of 1 and 1/2 inches.
6. Insert the screws through the holes in the mounting plate and into the holes you
drilled in the wall. Tighten the screws until the mounting plate is held firmly against
the wall. Do not overtighten the screws.
WARNING: The SB3800U weighs 85 lb. (38 kg). To avoid injury, be
sure to use proper lifting techniques and assistance in the unpacking
and installation of the inverter.
7. Carefully lift the SB3800U onto the mounting bracket. There are two small slots in
the top of the SB3800U. These slots sit on the pair of tabs on the top edge of the
mounting plate. Mount the SB3800U so that it hangs on these tabs. (see #2 in Fig-
ure 3-5).
8. Inspect the SB3800U from both sides to ensure that the channels on the back of the
SB3800U sit completely on the tabs on the top edge of the mounting bracket and
that the SB3800U is centered on the bracket.
9. Insert the hex screw and lock washer (included in the accessories package) in the
hole in the bottom of the SB3800U (#3 in Figure 3-5).
10.Tighten the screw to 44 inch pounds or 5 Nm. (Do not overtighten)
11.Verify that the SB3800U is securely mounted.
12.Snap the left and right exhaust fins into the SB3800U (Look for the L & R on the
inside of the fins.)
