2.0 INSTALLATION Surface Mounting • Using the mounting bracket as a template, mark the positions for the screw holes and an area where the cable(s) will feed through. • Drill out the four screws holes (if required) and wire access opening. Use a 3/16" bit if the supplied plastic anchors are used. If placing the screws directly into the backing material, use a 3/32" bit. The wire access hole should be at least 1/2" diameter to allow the connector to pass through. • Mount the bracket using the

2.0 INSTALLATION 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. Maximum Distance Wire Gauge 250 feet #16 AWG 400 feet #14 AWG 630 feet #12 AWG 1000 feet #10 AWG J2 TO INV

3.0 CONFIGURATION Setting Parameters (continued) % Charge Efficiency Since batteries are not 100 percent efficient, more energy is required to charge them than can be extracted. Some of this energy is lost in the form of heat and gassing. An efficiency factor of 94 to 98% is typical for lead-acid batteries. Consult the battery manufacturer’s specifications for other battery types. Set this value to 96% for new batteries and 94% (or lower) for batteries already in service. The default setti
