3 Installation Model 3020T

For safe connections, ensure that no uninsulated wire extends outside of the connectors they are attached to. Stripped wire ends must insert com- pletely into terminal blocks. No uninsulated wiring should be able to come in contact with fingers, tools or clothing during normal operation.

3.3.1 Primary Input Power

The universal power supply requires a 115 or 230 V ac, 50 or 60 Hz

power source. The actual input voltage used must show in the window of the VOLTAGE SELECTOR switch before the power source is connected. See Figure 3-4 for detailed connections.

DANGER: Power is applied to the instrument's circuitry as long as the instrument is connected to the power source. The Standby function switches power on or off to the displays and outputs only.
