IMPORTANT SAFETY INSTRUCTIONS
Safety Admonishments Definitions
Definitions of the safety admonishments used in this document are listed under “Admonishments Used in this
Document” on page 5.
General Safety
DANGER! YOU MUST FOLLOW APPROVED SAFETY PROCEDURES.
Performing the following procedures may expose you to hazards. These procedures should be
performed by qualified technicians familiar with the hazards associated with this type of equipment.
These hazards may include shock, energy, and/or burns. To avoid these hazards:
a) The tasks should be performed in the order indicated.
b) Remove watches, rings, and other metal objects.
c) Prior to contacting any uninsulated surface or termination, use a voltmeter to verify that no voltage
or the expected voltage is present. Check for voltage with both AC and DC voltmeters prior to
making contact.
d) Wear eye protection.
e) Use certified and well maintained insulated tools. Use double insulated tools appropriately rated for
the work to be performed.
Handling Equipment Containing Static Sensitive Components
ALERT! Installation or removal of equipment containing static sensitive components requires careful
handling. Before handling any equipment containing static sensitive components, read and follow the
instructions contained on the Static Warning Page.

STATIC WARNING
This equipment contains static sensitive components. The warnings listed below must be observed to
prevent damage to these components. Disregarding any of these warnings may result in personal injury
or damage to the equipment.
1. Strictly adhere to the procedures provided in this document.
2. Before touching any equipment containing static sensitive components, discharge all static
electricity from yourself by wearing a wrist strap grounded through a one megohm resistor. Some
wrist straps have a built-in one megohm resistor; no external resistor is necessary. Read and follow
wrist strap manufacturer’s instructions outlining use of a specific wrist strap.
3. Do not touch traces or components on equipment containing static sensitive components.Handle
equipment containing static sensitive components only by the edges that do not have connector
pads.
4. After removing equipment containing static sensitive components, place the equipment only on
static dissipative surfaces such as conductive foam or ESD bag. Do not use ordinary Styrofoam™or
ordinary plastic.
5. Store and ship equipment containing static sensitive components only in static shielding containers.
6. If necessary to repair equipment containing static sensitive components, wear an appropriately
grounded wrist strap, work on a conductive surface, use a grounded soldering iron, and use
grounded test equipment.

INTRODUCTION
Overview
The SM-IO2 consists of an SM-DUE enclosed in a sheet metal housing. The SM-IO2 is used in applications
where an SM-DUE is mounted external to a power system equipped with an NCU controller. The SM-DUE is
used to input external monitoring information to the NCU controller. The SM-DUE provides the following
monitoring inputs:
•Ten (10) input blocks with each providing the following monitoring inputs:
-One (1) Load Bus Voltage (0 VDC to 60 VDC) per input block
-One (1) Load Fuse Alarm (Bus- base of 0 VDC, >10 VDC alarm, <10 VDC normal) per input block
-One (1) Programmable Analog Input, can be set to accept one (1) of the following inputs per input
block:
10 mV DC to 50 mV DC Load Shunt (only load shunts are supported at this time)
General-Purpose Current Transducer
General-Purpose Voltage Transducer
1 uA/K Temperature Sensor
NOTE! Only the SM DUE designated as SMDUE1 and SMDUE2 via the addressing switches can have
temperature probes connected to them.
The SM-DUE also contains a +5 VDC power supply output for connection to external Hall devices.
The SM-DUE connects into the NCU CAN bus.Up to eight (8) SM-DUE units can be connected to an NCU.
Refer to Figure 1for illustrations of the SM-IO2.
