The DC wiring enclosure is located on the top right side of the inverter system to permit
connection of the two cables from the battery. Cable clamps are provided to secure the cables
after they are terminated in the wiring enclosure. A removable cover allows access to the wiring
enclosure.
DC input studs have been provided to accommodate crimp or compression lugs (Vanner part no.
04505, ILSCO part no. TZ-250 #6-250 mcm or similar) with 5/16” hole with battery cable up to 4/0
awg cable. Good DC connections are critical for the performance and safe operation of the
inverter system. Torque the DC input stud nut to 119 – 158 in. lbs. and repeat torque procedure
after 30 days. The positive and negative cables enter the compartment through separate strain
reliefs located at the upper right side of the unit.
Table below shows the recommended minimum cable size which should be used. Wire sizing
charts published in the NEC may allow a greater amp capacity than we recommend. We have
sized the cable for a maximum voltage drop to maintain better performance of your inverter
installation. For best performance, wire the DC negative directly back to the battery, and in the
case of a mobile installation, do not use the vehicle chassis as the DC negative conductor.
The wiring of your inverter installation should conform to the National Electric Code (NEC) and
any other state or local codes in effect at the time of installation. Article 551 of the NEC requires
any DC cable from a battery, which measures longer than 18 inches along its length, be protected
by a fuse.
