Wall-Mounting
Wallboard is not strong enough to support the weight of the inverter, so
additional support must be added. This can be in the form of reinforcing
2 x 4’s or a half sheet (4 ft x 4 ft) of ¾-inch plywood.
Wall Mounting
using 2 x 4’s
The easiest method for securing the inverter to an existing wall is to place
two 2 x 4’s horizontally on the wall (spanning at least three studs) and
securing the inverter to the 2 x 4’s.
To mount the Sine Wave Plus on a wall, follow the instructions below.
1. Locate the studs and mark their location on the wall.
2. Measure the desired height from the floor for the inverter to be
mounted. The height should place the inverter’s control module at the
operator’s eye level for easy viewing and setting.
3. Using a level, run a horizontal line. The length of the line must span
at least 3 studs.
4. Place a pre-cut 2 x 4 on the marked location and drill pilot holes
through the 2 x 4’s and studs.
5. Secure the 2 x 4 with #10 wood screws (length to penetrate 1½ inches
or more into the studs).
6. Repeat the procedure for the remaining 2 x 4 (paint the 2 x 4’s, if
desired, to match the surrounding wall).
7. Drill mounting holes in the 2 x 4 mounting rails by one of the
following methods. Be sure to use all of the inverter mounting holes
and keyhole slots for mounting.
a) Using the measurements from Figure 3-3 drill out the mounting
hole locations for the inverter.
b) Create a cardboard template by tracing around the inverter and
marking the mounting holes and keyhole slots on the cardboard.
Use the cardboard template to locate and drill the mounting holes.
8. Ensure that the 2 x 4’s are securely fastened to the wall before
mounting the inverter to them.
9. With assistance, lift the inverter into position and install it onto the
2 x 4’s using ¼ x 1½-inch lag bolts and washers.
