SECTION 2 - INSTALLATION
INTRODUCTION
This section explains how to configure and install the NIAO01
Analog Output Termination Module. Read, understand and
complete the steps in the order they appear before using the
IAO termination module.
SPECIAL HANDLING
Observe these steps when handling electronic circuitry:
NOTE: Always use Bailey's Field Static Kit (part number
1948385A1 - consisting of two wrist straps, ground cord assembly,
alligator clip and static dissipative work surface) when working with
the modules. The kit grounds a technician and the static dissipative
work surface to the same ground point to prevent damage to the
modules by electrostatic discharge.
1. Use Static Shielding Bag. Keep the modules in the static
shielding bag until you are ready to install them in the system.
Save the bag for future use.
2. Ground Bag Before Opening. Before opening a bag con-
taining an assembly with CMOS devices, touch it to the equip-
ment housing or a ground to equalize charges.
3. Avoid Touching Circuitry. Handle assemblies by the
edges; avoid touching the circuitry.
4. Avoid Partial Connection of CMOS Device. Verify that all
devices connected to the modules are properly grounded before
using them.
5. Ground Test Equipment.
6. Use Antistatic Field Service Vacuum. Remove dust from
the module if necessary.
7. Use Grounded Wrist Strap. Connect the wrist strap to the
appropriate grounding plug on the power entry panel. The
grounding plug on the power entry panel is connected to the
earth grounding electrode system through the AC safety
ground.
8. Do Not Use Lead Pencils to Set Dipswitches. To avoid
contamination of switch contacts that can result in unneces-
sary circuit board malfunction, do not use a lead pencil to set a
dipswitch.

Dipswitch Configuration
The dipswitches select the analog output type (voltage or cur-
rent) for the field device connected to the termination module.
Each channel is independent. Set the dipswitches for voltage or
current. Table 2-1 shows how to set dipswitches one through
eight (analog outputs one through eight respectively). Refer to
Appendix A to find the dipswitch settings for the analog output
module.
Cabling Connections
The IAO termination module provides termination points for
