Table 9E — Medium-Static Drive Data, 60 Hz — SI
*Four belts shipped with unit. Use correct set of 2 belts sized according to the pulley setting.
Table 9F — High-Static Drive Data, 60 Hz — SI
*Values for 3-phase motor shown. For single-phase motor, pulley pitch diameter is 178 mm and
resulting fan speed is 14.0-18.3 r/s.
†It is possible to adjust drive so that fan speed exceeds maximum allowable. DO NOT exceed
20 r/s.
**575-v unit has a center distance of 233-279.
