WIRE SUGGESTIONS ACCORDING TO "1999 NEC" BASED ON ROOM TEMPERATURE 30ºC & SINGLE COOPER CABLES WITHOUT
CONDUIT.
WARNING: The correct wire gauge or section is strongly affected by diverse factors such as: room temperature,
wire length, type of wire and kind of installation. User or his electrical contractor must assure an appropriate
selection for wire and other devices for complying with local electrical regulations and directives.
WARNING: For ISOTX models: When using two 110VAC outputs separately, each output only will be able to drive
50% of total UPS capacity. For example, for 10KVA UPS, each 110Vac output will drive 5KVA max.
