3 Installation Model 3020T
3-4 Teledyne Analytical Instruments
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.

Fuses are not installed at the factory. Be sure to install the proper fuse as part
of installation. (See Fuse Replacement in chapter 5, maintenance.)
3.3.3 Analog Outputs
There are eight DC output signal connectors on the ANALOG OUT-
PUTS connector block. There are two connectors per output with the polar-
ity noted. See Figure 3-5.
