Overview
CRACs and CRAHs monitor and maintain the temperature, air distribution, and humidity
in a data center. CRACs use mechanical refrigeration; CRAHs use fans, cooling coils,
and a water-chiller or glycol cooling system.
The CRAC and CRAH configurations described in this document are upflow, downflow,
and row cooling loosely based on the leading manufacturers of CRACs and CRAHs,
Liebert® and Stulz®. The diagrams and illustrations in this guide detail the general
installation of cable assemblies, sensors, and ThermaNodes for common CRAC/CRAH
configurations.

Warnings and Precautions
The following warnings and precautions pertain to the CRAC/CRAH sensor installation.
Failure to adhere to warnings and precautions could result in physical injury or damage
to equipment, which may void the warranty.
Warning: When performing subfloor work in a data center, be careful not
to stress, crush, pull, or disconnect wiring and hoses running underneath
electrical and data cables, leak detectors, etc. (including fire
alarm/suppression systems).
Warning: Subfloor work poses significant trip/fall hazards and eye
hazards from airflow-
borne debris. Eye protection must be worn at all
times when removing or replacing floor tiles and when working in or
around areas with removed tiles.
Warning: Do not touch any data center electrical or computer/server
equipment without approval from data center operators (including loose
cables, pushcarts, and terminals).
Safety Warning: Installation of this equipment must be in accordance
with local and national electrical codes.
Safety Warning: This product contains Lithium metal primary cell
batteries, which are NOT rechargeable. Recharging can cause battery
leakage or cause the safety release vent to open. Inadvertent charging
can occur if battery installation is backwards.
Dispose of batteries
appropriately after use.
Safety Warning: Lithium metal batteries may pose a fire, explosion, or
burn hazard if misused. Do not open battery, dispose of in fire, heat above
100° C (212° F), expose contents to water, recharge, put in backwards,
mix with used or other battery types as this may cause the batteries to
explode or leak and cause personal injury.
Safety Warning: Lithium metal batteries must be properly packed and
shipped in accordance with transportation standards.
Safety Warning: Data centers may pose a risk of hearing loss. Use
appropriate ear protection prior to entry into high-noise areas.

Getting Started
Required Hardware
The required hardware for this installation is contained in the CRAC/CRAH sensor kits.
CRAC/CRAH Sensors installation kits contain:
•ThermaNode:
−Transmits data from cable assembly sensors and to the gateway
−Contains four AA-size batteries
−Contains a pin plug that accepts sensor assemblies
•CRAC/CRAH Cable Assembly:
ThermaNodes connect to a 2-sensor cable assembly
that measures return and supply air temperature and
humidity. The cable assembly includes:
−Plenum-rated material
−Return and supply wires measuring 10’ in length
−Stainless steel sensors
−Labels for supply and return wires
•Adhesive-backed cable clips
•Regular and plenum-rated (purple) zip ties (not shown)
•3M Command Strips™ (not shown)
Required Software
The environmental server requires the installation of the following SynapSense
software:
•Web Console™

•MapSense™ (including optional Active Control™ software with MapSense project *.dlz file exported
into the Web Console)
Installation of SynapSense software generally takes place prior to hardware installation,
which prevents redundancy of hardware verification activities. Refer to the SynapSense
Software, Web Console, and MapSense Installation and User Guides for more
information.

Installing CRAC/CRAH Sensors
General Installation Guidelines
Ensure software installation and required file exports before installing hardware
Be consistent. Match all installations in appearance including node/sensor locations,
centering, wiring, and method for securing extra cable
Be neat.
•Ensure wiring is straight and vertical or horizontal as much as possible
•Follow the existing wire bundle path of the CRAC/CRAH where possible
Secure wires appropriately.
•Pull slack wire taut
•Loop extra wire and tie securely at one or more of the sensor locations to prevent wiring from
dangling or moving
Install clips properly.
•Clean surfaces thoroughly with alcohol wipes and allow cleaned surfaces to dry
•Align clips neatly (vertical or horizontal) in the same direction as wiring
•Hold clip in place for 30 seconds to ensure adhesive bonding
Use Zip Ties where needed.
•Pull wire(s) taut to prevent slippage but not so tight to cause pinched wiring
•Use diagonal cutters to clip zip tie ends close to its locking mechanism
•Use fire code compliant, plenum-rated (usually purple) zip ties to secure cable assembly and
sensor wire to the CRAC/CRAH stand
•Follow all site safety procedures and protocols
Safety Warning: HIGH VOLTAGE! Most CRACs and CRAHs are 3-
phase, which can cause electric shock possibly resulting in injury or
death.
Safety Warning: Ensure Facilities Supervisor or designee disconnects
local and remote power supplies before starting sensor installation work.
Safety Warning: Contact with moving parts, such as fans, could cause
injury or death.
Safety Warning: Ensure Facilities Supervisor or designee disconnects
all local and remote electric power supplies before starting sensor
installation work.
