Manual Self-Protected (Type E) Combination Motor Controller, UL listed for 208 Wye or Delta, 240 Wye or Delta, 480Y/
277 or 600Y/347. Not UL listed for use on 480V or 600V Delta/Delta, corner ground, or high-resistance ground systems.

(4)

When using a Manual Self-Protected (Type E) Combination Motor Controller, the drive must be installed in a ventilated or
non-ventilated enclosure with the minimum volume specified in this column. Application specific thermal considerations
may require a larger enclosure.
