IMPORTANT NOTICE

This installation guide provides basic guidelines for the CSI 9420. It does not provide
instructions for detailed configuration, diagnostics, maintenance, service, troubleshooting,
or installations. Refer to the CSI 9420 reference manual (document number P/N 97408)
for more instruction. The manual and this QIG are also available electronically on
www.mhm.assetweb.com.

WARNING

Explosions could result in death or serious injury:

Installation of this transmitter in an explosive environment must be in accordance with the
appropriate local, national, and international standards, codes, and practices. Please
review the Product Certifications section for any restrictions associated with a safe
installation.

• Before connecting a 375 Field Communicator in an explosive atmosphere, ensure the
instruments are installed in accordance with intrinsically safe or non-incendive field
wiring practices.

Electrical shock can result in death or serious injury

• Avoid contact with the leads and terminals. High voltage that may be present on leads
can cause electrical shock.

IMPORTANT NOTICE

The CSI 9420 and all other wireless devices should be installed only after the 1420
Wireless Gateway has been installed and is functioning properly . Wireless devices should
also be powered up in order of proximity from the 1420 Wireless Gateway , beginning with
the closest. This will result in a simpler and faster network installation.

IMPORTANT NOTICE

Shipping considerations for wireless products (Lithium Batteries):

Battery powered units are shipped without the power module installed. Please remove the
power module pack prior to shipping the unit.

Primary lithium batteries are regulated in transportation by the U.S. Department of
Transportation, and are also covered by IATA (International Air Transport Association),
ICAO (International Civil Aviation Organization), and ARD (European Ground
Transportation of Dangerous Goods). It is the responsibility of the shipper to ensure
compliance with these or any other local requirements. Please consult current regulations
and requirements before shipping.

This Quick Installation Guide applies to both the 2.4 GHz and 900 MHz Wireless HART
versions of the CSI 9420. If you are unsure which version the device is, look in the upper
right-hand corner of the nameplate, as illustrated in Figure 1 below.

STEP 1: PHYSICAL INSTALLATION

The CSI 9420 and all other wireless devices should be installed only after the 1420 Wireless
Gateway has been installed and is functioning properly.

Powering the CSI 9420

Remove the rear cover of the device to access the power connections. For the battery
powered version, simply plug in the power module. For the externally powered version,
connect a 10...28V DC (24V nominal) power supply to the bottom two screw terminals on
the right (see Figure 3). Pull the wiring through the threaded conduit entry. When selecting
the power supply, note that each CSI 9420 has a peak current draw of 40 mA when awake
and powering sensors.

NOTE:

Wireless devices should be powered up in order of proximity to the 1420 Wireless
Gateway, beginning with the closest device to the 1420. This will result in a simpler
and faster network installation.

GENERAL SENSOR HANDLING INSTRUCTIONS

The CSI 9420 utilizes special low-power sensors available from Emerson. Each sensor
requires a standard 1/4” - 28 mounting location. Refer to the User’s Manual for detailed
sensor mounting instructions. Sensor mounting instructions and practices are also available
in a separate Sensor Installation Guide on the CD packaged with this device and at
www.mhm.assetweb.com.

To maintain mechanical isolation of the sensor, a Remote Mount configuration is required,
as illustrated in Figure 2. In this configuration, the sensor is mounted separately from the
CSI 9420 housing, then connected to the CSI 9420. Although not required for all
installations, it is common to run the cable from the sensor to the housing through conduit.

NOTE:

The word “sensor” applies to both an accelerometer and an accelerometer with
embedded temperature. The word “accelerometer” refers to a sensor that measures
only acceleration.

Remote Mount

1. Install sensor or accelerometers according to standard sensor installation practices. Be
sure to use thread sealant on all connections.

2. Run wiring (and conduit if necessary) from the sensor to the CSI 9420.

3. Pull the wiring through the threaded conduit entry of the CSI 9420. If not using conduit,
an appropriate grommet or cable-gland should be used to provide both strain relief for
the cable and environmental isolation for the CSI 9420.

4. Attach the sensor wiring to the terminals as indicated in tables 1-3.

5. Connect the power pack module or external 24V DC power supply.

6. Close the housing cover and tighten to safety specification. Always ensure a proper seal
by installing the electronics housing covers so that metal touches metal, but do not over

tighten.

7. Position the antenna such that it is vertical, either straight up or straight down.

Figure 2. Remote mounting of the CSI 9420 involves mount ing the device away from the eq uipment to be
measured (upper left), connecting a sensor or acce leromete rs t o the equi pment and t he CSI 9 420 (upp er
right), and removing the rear cover and power module of the de vi ce to co nnect the sensor wire s (bot to m).
