Technical Data 460V Class continued
Technical Data
1) The wire gauge is based on the maximum fuse rating, copper wire with minimum 75°C insulation rating, THHW or equivalent.
If branch circuit protection is selected based on rated input current, the wire size could be reduced.
2) With the regulated systems F5-M as well as F5-S 5% must be subtracted as control reserve
3) Rated operation means, rated input voltage, rated output current, and rated carrier frequency.
4) This data is only valid for units with internal brake transistor GTR 7 (see "unit identification")
5) The maximum cable length is the same for all carrier frequencies.
