When connected to a 208Y/120 Vac three-phase, four-wire system, field phase balancing of two out of every three stacks is required. One of every three stacks should be phased, per Figure, and one of every three stacks should be phased, per Figure. Examples: ine Total Positions use (three) three-position stacks and phase one per Figure (- phasing) and one per Figure (- phasing). 16 Total Positions use (two) five-position and (two) three-position stacks. Phase balance (one) five-position per Figure (- phasing) and (one) five-position per Figure (- phasing). 19 Total Positions where four-position maximum height is allowed by utility. Use (one) four-position and (five) three-position stacks. Phase balance (two) threeposition stacks per Figure (- phasing) and (two) three-position stacks per Figure (- phasing).
