Mounting the Radio Piggy-Back Board
After verifying the group setting, the Radio Piggy-Back may be mounted by gently pressing it
onto the pins as shown in the illustration below.
NOTE: Be sure to support the inverter circuit board from underneath when
mounting the Piggy-Back. Excessive flexing of the circuit board may damage it.
Press the Piggy-Back in place until it is fully seated against the connectors on the circuit board.
Figure 1-3 Installing the Radio Piggy-Back Board
Installation of the Radio Piggy-Back Board in SWR Type Inverters
If the Radio Piggy-Back boards are to be installed in an SWR type inverter, (this can be verified
by checking the ratings label on the side of the inverter, e.g. SWR2500U/SWR1800U) an
additional step must be taken. The SWR type inverters require the cutting of two resistors
located on the circuit board where the Piggy-Back board will mount. See the following
illustration. (This is not required for other SMA inverters.)
To cut these resistors:
Use a small pair of wire cutters
Cut the lower lead close to the circuit board
Lift the resistor just enough to prevent connection
Repeat for the second resistor
