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 100-240 VAC, 50 or 60 Hz

power source. 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.

3.3.2 Fuse Installation

The fuse holders accept 5 x 20 mm, 4.0 A, T type (slow blow) fuses.

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.
