INTRODUCTION
This document details installing:
• New Emerson® wireless solutions, including wireless gateway and wireless nodes
• Adding wireless nodes and wireless gateways, if necessary, to expand an existing wireless
network.
Emerson’s wireless solutions are designed to be installed indoors only, using traditional work
practices to ensure accurate measurements. The system will consist of a wireless gateway and
wireless nodes.
Wireless Gateway
The wireless gateway provides several functions, including interfacing with the monitoring system,
managing communication with the wireless nodes and collecting data from the wireless nodes. A
wireless node consists of the radio for the wireless communication with the gateway and the sensor
string (cable with three temperature sensors). Together these devices create a system to provide an
easy-to-deploy, adaptable solution to monitor an environment.
Emerson wireless devices based on IEC 62591 (WirelessHART) technology use small amounts of
bandwidth, enabling high-priority communications. Security and reliability have been engineered
into the WirelessHART standard utilizing proven industry standards. However, one of the most
important features Emerson wireless solutions is the extremely low power requirement.
Wireless Nodes
Each wireless node is a battery-powered radio with a sensor string for monitoring the conditioned
space. Emerson recommends placing the radio on top of the rack and attaching the sensor string to
the rack door with the temperature sensors strategically spaced to provide top, middle and bottom
monitoring of a rack.
1.1
Integration with Monitoring System
The wireless network must be integrated with a monitoring system. An Emerson wireless network is
compatible with:
• Liebert® SiteScan® Web
• Emerson’s Trellis™

•
•
•
•
•
Mount the wireless gateway and power supply where they are easily accessible
Mount the wireless gateway and power supply indoors on a solid, non-metallic surface
2.5 feet (0.76m) above any obstruction (higher placement increases wireless range)
2.5 feet (0.76m) from a vertical surface that might cause radio interference
DIN rail must be grounded in accordance with national and local electrical codes. Attaching the
wireless gateway to the DIN rail grounds the gateway.
• Away from metal obstructions, such as metal partitions or wide cabinets
• Maximize the number of wireless nodes in line-of-sight with the wireless gateway. This may lead
to longer battery life, more efficient network formation and faster startup.
• Mount near an input power source—100-240VAC with UPS backup

Mounting the Power Supply and Wireless Gateway
2.4.1
Mount the DIN Rail
1. Determine the mounting location. Consider the size of the wireless gateway and power supply and
radio reception as determined in the design phase.
2. Hold the DIN rail against the wall and mark two hole locations.
3. Drill the holes to accept the mounting screws.
4. If using the provided hardware, the holes must accommodate a 1/4" drywall anchor; in sheet
metal, drill pilot holes for a #10 screw.
5. Screw the rail to the wall.
6. Ground the DIN rail according to national and local electric codes.
NOTE
The most effective grounding method is a direct connection to earth ground with minimal
impedance. Grounding to the wireless gateway is accomplished through the DIN rail clip on
the back of the gateway.

Record Each Wireless Node’s MAC Address and Location
Before beginning to install the wireless nodes, record each unit’s MAC
address and physical location. This information should be noted on the
document used to design the wireless network.
Recording each wireless node’s MAC address and physical location
eases data collection and troubleshooting. For example, if a sensor
reports high temperatures in a rack, knowing where that sensor is
installed enables correcting the cause before the equipment overheats.
A wireless node’s MAC address may be difficult to see after installation.
The MAC address location and part number are shown at right.
2.7
Mount the Wireless Nodes
MAC Address
Part #
Location
The wireless nodes may be placed so that the sensors monitor either the Location
intake (cold) air or the exhaust (hot) air. These instructions are for
monitoring the intake air. To monitor exhaust air, place the wireless nodes and sensor string on the
rear of the rack.
When fully installed, a wireless node is positioned on top of the rack with the fewest possible
obstructions that might degrade the radio signal. The sensor string runs down the inner side of the
rack door, along the door hinge side and along the door’s midline.
1. Record each wireless node’s MAC address and physical location in the facility.
2. Attach the wireless node on top of the rack, either with supplied hook-and loop-fasteners or with
cable fasteners. (The wireless node has slots on each end for the cable fasteners).
NOTE
The hook-and-look fastener has adhesive to attach to the wireless node. Do not attach the
fastener so that it covers any of the labeling.
If necessary, clean the rack and the wireless node with the included alcohol swab.
3. Route the sensor string through an opening in the rack—protect the wiring from being pinched.
4. Attach the sensor string to the inside of the rack door with at least one cable fastener, leaving
enough cable slack so that the door will open without stretching or pinching the wire.
5. Space the sensors evenly on the rack door. Keep the cable straight and tight while securing the
sensor string.
6. Trim excess cable fastener material and discard it.

Commissioning the Wireless Solutions
3.0
COMMISSIONING THE WIRELESS SOLUTIONS
Liebert Services will commission the wireless network components:
• Wireless Gateway
• Wireless Nodes
• Wireless Monitoring System (procedures vary according to system)
Liebert Services will perform the following steps.
3.1
Wireless Gateway
• Verify proper input power and UPS backup.
• Verify all devices are connected with a reliability at or above 99%.
• Verify that at least 15% of the wireless nodes are communicating directly with the wireless
gateway instead of through a neighbor wireless node.
The design rule is 25% of wireless nodes due to the dynamic nature of the environment; the
commission rule is 15%.
• Load the Modbus register mapping into the wireless gateway.
3.2
Wireless Nodes
• Verify that the wireless nodes are properly installed.
• Configure Network ID and Join Key, giving each wireless node proper security to join a unique
wireless network.
• Verify through the wireless gateway that each wireless node has at least two neighbors.
• The design rule is three neighbors, due to the dynamic nature of the environment; the commission
rule is two neighbors.
• Verify through the wireless gateway that the data is updating at the desired rate.
3.3
Wireless Monitoring System
• Verify data from the wireless gateway appears in the monitoring application.
• Interface with BMS contractor to verify operation and setup with BMS system.
3.4
Wireless Network
When complete, all wireless connections between wireless
nodes can be viewed live in the DCIM application. The
effective range of the wireless network may exceed the
design distance. The self-organizing technology
essentially places a wireless engineer inside of each
WirelessHART compliant wireless node that dynamically
responds to the current state of the environment. The
self-organizing technology will always use the best
possible links and the conservative application of design
rules ensures an adequate number of potential
connections from which the best connections can be
chosen by the radios, without the user needing to be a
wireless expert.
