Auxiliary Switch Port Jumper | Thomas & Betts 20D, 15D specs

INSTALLATION

9.Do not back-feed the AC output of the inverter with incoming AC power. A back-feed occurs when AC power from shore power or generator is connected to the output of the inverter. This will damage the inverter and void the warranty. Remember that incoming AC must be fed only to the AC input and never the AC output. Always check for AC voltage before connecting wires to the AC output. Do NOT turn the inverter ON until all AC connections have been made. Back- feeding the inverter voids the warranty.

WARNING

Do not connect incoming AC from any source to the AC output of the inverter. This is known as back-feeding and will damage the unit and void the warranty.

10.Do not connect the AC input to the AC output. This would be equivalent to plugging the battery charger into the inverter. This could occur if the unit’s AC output is connected to the entire leg of a circuit breaker panel, then a circuit breaker on that leg is used to feed the battery charger input. This will cause the unit to oscillate ON and OFF when the unit is in inverter mode.

11.Always use proper wire and connectors. The proper battery cable size is critical. Considerable amperage flows in the DC circuit. Use 2/0 UL Listed Welding Cable terminated on each end with UL Listed or UL Recognized ring terminal connectors. For the terminal, use Thomas & Betts (T&B) part number BAL 2038. Be sure the connectors are attached to the cable using a method approved by the connector manufacturer. For the connections to meet all requirements, T&B recommends that each terminal be crimped in

two places with a pressure of 15 tons using a hexagonal die. The T&B die has a code number of 54. After the crimp is made, the barrel of the terminal and the first inch of the cable needs to be covered in UL Listed or UL Recognized heat shrink tubing. Heart Interface recommends a 2-inch length of 3M HDT 0800 tubing. Other heat shrink may be used if it is UL Listed or UL Recognized as long as the manufacturer’s directions are followed.

12.If installing in a system which includes an existing battery charger or AC to DC converter, make sure these do not operate from the inverter output AC power. This sets up a power loop which, due to inefficiencies, will quickly drain the batteries.

13.An Auxiliary Switch port is located on the front panel of the unit, covered by a flap. When installing the unit for operation without a Remote Control Panel or Link Instrument, a jumper must be installed in the Aux Switch port. The jumper is shipped in a plastic bag with other installation parts. DO NOT install the jumper until all cable connections have been made.

When using a Remote Control Panel or Link Instrument, the jumper is not used.
