2.4. APPLICATION INFORMATION
2.4.1. AC VOLTAGE SENSING INPUT
The TSC 80e can accept direct AC voltage sensing inputs on the generator and utility
supplies from 120-600VAC (nominal). Note: Direct input voltage sensing can only be
used when the system utilizes a 3 phase, 4 wire distribution system which has the
neutral conductor solidly grounded. For 3 phase, 3 wire systems (i.e. no neutral) or
high voltage systems, potential transformers must be used. Refer to FIGURE 3 for
voltage sensing connections.
