Recommended Torque
Values
When reinstalling components, or when reassembling the cabinet, tighten the
following bolt sizes to the specified torque values:
Environmental Conditions The controller must accept nominal plant power of 2400V, 3300V, 4200V,
4800V, 5500V, 6600V, 6900V (+5/-15%), or 7200 (+0/-15%), 3 phase 50/60 Hz
