AC Voltage Inputs

The Model 1133A has a single, Phoenix-style, connector block that connects up to four different
phase voltage inputs to the measurement section. Wires are anchored by set screws in the connector
plug, and the connector plug is inserted into the connector block on the rear panel. The connector
plug is anchored with screws. Figure 2.6 illustrates the connector block on the rear panel.

AC Current Inputs

The Model 1133A has a single, Phoenix-style, connector block that connects up to three different
phase current inputs to the measurement section. Wires are anchored by set screws in the connector
plug, and the connector plug is inserted into the connector block on the rear panel. The connector
plug is anchored with screws. Figure 2.7 illustrates the connector block on the rear panel.

Event Inputs

The Model 1133A has four two-terminal connectors (illustrated in Figure 2.8) for timing external
events based on the GNSS-synchronized time, of from an IRIG-B signal. Since events can range
widely in voltage level, inputs may be configured for different ranges. See Chapter 14 for additional
information on setting the event input voltage level.
