Interconnection
Caution
Meggers and high potential test equipment must not be used.
Incorrect use of such equipment could damage the semiconductors
contained in the regulator.
General
The regulator must be connected to the generator system as instructed in this chapter and as shown in
the basic interconnection diagrams (Figure 7 and Figure 8). A minimum of 16 AWG (1.29 mm) wire
should be used for all connections to the regulator.
Regulator Sensing (Terminals E1, E2, and E3)
Caution
The SR6A & SR9A Voltage Regulators are factory preset for 120 Vac
sensing.
The voltage regulator contains an internal sensing transformer(s) T1 (T2) provided with taps for various
input sensing voltages. These sensing voltages are: 120, 208, 240, 416, 480, and 600 Vac (refer to
Figure 6). The model number of the unit designates single-phase (T1) or three-phase (T1 and T2)
sensing. For operation with generator voltages above 600 Vac, a potential transformers(s) must be used
to supply the regulator sensing voltage. The regulator sensing circuit load is less than 10 VA and correct
polarity must be maintained to the regulator sensing input.
