Cable Sizes and
Current
The following table indicates the recommended sizes of conductors in accordance with the NEC
®
. (Air
temperature surrounding the conduits not greater than 104°F (40°C).)
NOTE: Cable sizes are suggested and based on standard configurations. Installers should verify correct
conductor sizes pursuant to NEC
®
and/or state or local codes. If the installation requires long conductor
runs, consult NEC
®
and/or state or local codes to account for electrical losses.

‡ Wire between JL1 & BL1 and between JL2 & BL2 if only single input power source is used.
‡‡ Output voltage available at output terminals dependent on specific model. See Table 5 - 7 on page 13 for details.
* Use insulated copper wire rated 90°C minimum
** Must be no smaller than wire connected to L1 and L2
NOTE: For installation per IEC regulations: If installing units per regulations IEC-287 and DIN VDE 0298, 6 kVA model
should be wired (inputs and outputs) with 6 mm
2
cable torqued to 2.5 nt-m; and 10kVA model (inputs and outputs) should be
wired with 10 mm
2
cable torqued to 2.5 nt-m. (Based on 90°C cable and ambient of 40°C)
