Extended Length Installations
If the TM500A is mounted in excess of 100 feet from the inverter, an
additional wire (with a spade lugs on both ends) must be connected between
the TM500A and shunt spade lugs. This wire acts as a ground reference and
ensures the meter will read accurately.
Use the following gauge wire for the distance the TM500A is mounted
from the inverter.
