vicinity of batteries. Review cautionary markings on these products and all other products
being used.
7. No terminals or lugs are required for hook-up of the AC wiring. AC wiring must be no less than
10 AWG (5.3 mm ) copper wire and rated for 75 C or higher. Battery cables must be rated for
75 C or higher and should be no less than the minimum wire size recommended by this manual.
Crimped and sealed copper ring terminal lugs with a 5/16" hole should be used to connect the
battery cables to the DC terminals of the inverter/charger. Soldered cable lugs are also
acceptable. See section Batteries and Chargers for correct battery cable size and length for your
application.
8. Torque all AC wiring connections to 15-20 inch-pounds. Torque all DC cable connections to 10-
12 foot-pounds.
9. CAUTION: To reduce the risk of fire, use only input circuits provided with the correct ampere
branch circuit protection in accordance with the National Electric Code, ANSI/ NFPA70
10. Use the correct tools to make AC/DC wiring connections: wire strippers, ½" (13mm) open-end
wrench or socket, Phillips screw driver #2, and ¼" flat blade screwdriver (6mm).
11. This inverter/charger should be used with a battery supply of 12-volts DC nominal voltage.
12. Do not install this inverter/charger on or near flammable materials (plywood, chemicals, gasoline,
etc.)
13. The unit is designed for mounting on a flat surface only. Do not mount on a wall or hang
inverted.
14. No AC or DC disconnects are provided as an integral part of this inverter. Both AC and DC
disconnects must be provided as part of the system installation. See Installation section on Page
23 of this manual.
15. No overcurrent protection for the battery supply is provided as an integral part of this inverter.
Overcurrent protection of the battery cables must be provided as part of the system installation.
See Installation section of this manual.
16. No overcurrent protection for the AC output wiring is provided as an integral part of this inverter.
Over-current protection of the AC output wiring must be provided as part of the system
installation. See the Installation section of this manual.
17. GROUNDING INSTRUCTIONS - This inverter/charger should be connected to a grounded,
permanent wiring system. For most installations, the negative battery conductor should not be
bonded to the vehicle chassis ground. Connection of the large green chassis ground terminal on
the side of the inverter will create the battery negative to vehicle chassis ground. All installations
should comply with all national and local codes and ordinances.
18. AC Grounding Instructions – The inverter/charger includes neutral to ground switching for the AC
electrical system. The AC system in mobile installations must have the neutral physically
isolated from the ground throughout the load distribution powered by the inverter.
