15.1.7 Electrical characteristics of the transformers
If the phase-to-phase line voltage is greater than 690Vac, it is essential to use a step-down transformer between the bars and the PR120/V
module. Voltage transformers can be installed up to 15m away from the PR120/V module to which they are connected. Proper operation is
only guaranteed for star/star or delta/delta configurations.
The allowable primary and secondary rated voltages that must be set on the unit are specified in the table 15.1.5.2.
