Teledyne Analytical Instruments 19
THE ANALYZER WITH ITS FASTENING SCREWS.
ULTIMATELY, IT IS THE INSTALLER WHO ENSURES
THAT THE CONNECTIONS PROVIDE ADEQUATE
EMI/RFI SIELDING.
3.3.3.1 PRIMARY INPUT POWER
The power cord receptacle and fuse block are located in the same
assembly. Insert the power cord into the power cord receptacle.
CAUTION: POWER IS APPLIED TO THE INSTRUMENT'S
CIRCUITRY AS LONG AS THE INSTRUMENT IS
CONNECTED TO THE POWER SOURCE.
The standard power supply requires 110 VAC, 50/60 Hz or 220
VAC, 50/60 Hz (optional) power.
3.3.3.2 FUSE INSTALLATION
The fuse block, at the right of the power cord receptacle, accepts US
or European size fuses. A jumper replaces the fuse in whichever fuse
receptacle is not used.
3.3.3.3 50-PIN EQUIPMENT INTERFACE CONNECTOR
Figure 3-2 shows the pin layout of the Equipment Interface
connector. The arrangement is shown as seen when the viewer faces the
rear panel of the analyzer. The pin numbers for each input/output
function are given where each function is described in the paragraphs
below.

3.3.3.4 ANALOG OUTPUT
There are four DC output signal pins—two pins per output. For
polarity, see Table 3-1. The outputs are 0-1 VDC, 0-1 VDC, 4-20mA
DC, and 4-20mA DC.
The 1st and 3
rd
outputs (0-1 VDC, and 4-20mA DC) operate
analogously as do the 2
nd
and 4
th
outputs (0-1 VDC, and 4-20mA DC).
