Components
CAUTION
Extreme temperature hazard. Can cause damage to system
components. The Intelligent Equipment hardware is designed to operate
in ambient temperatures from -22 to 158 degrees F (-30 to 70 degrees C)
and in relative humidity up to 90% (non-condensing).
Machine-to-Machine (M2M) Gateway
The M2M Gateway is a factory tested and commissioned
device, which analyzes and delivers data to the cloud via
wireless (Wi-Fi, cellular) or local area network (LAN) connection.
The M2M Gateway implements security, including data delivery
via secure HTTPS using SSL, and whitelisting protection. In
the case of a unit ordered with Intelligent Equipment, the M2M
gateway will be factory-installed in the unit control panel. For
installation in retrot applications, see document section titled,
Chiller Installation Instructions on page 7.
Antenna
The provided Cellular/Wi-Fi antenna must be eld-mounted,
regardless of whether the Daikin Applied Intelligent Equipment
solution was ordered factory-installed or for retrot installation.
In most cases, only one of the two antennas will be installed
and connected to the M2M Gateway. The antenna has a
magnetic base, which is suitable for directly mounting to the
unit control panel or case.
Energy Management Module (EMM)
(Not on Gateway-on-the-Go, IE Express, or
WMC kits)
The EMM is a factory tested and commissioned device, which
monitors unit voltage, current, and power and transmits this
data to the M2M Gateway for delivery to the cloud. In the case
of a unit ordered with Intelligent Equipment, the EMM will be
factory-installed in the unit control panel. For installation in
retrot applications, see document section titled, Installing
Energy Management Module on page 9.
Current Transformers (CT’s)
(Not on Gateway-on-the-Go, IE Express, or
WMC kits)
Three Current Transformers (CT’s) are supplied with the
Intelligent Equipment solution. At the time of order, the
Maximum Current Ampacity (MCA) for the unit is specied,
thereby driving selection of appropriately-sized CT’s (See Table
1 for CT sizing and specications). In the case of a unit ordered
with Intelligent Equipment, the CT’s will be factory-installed
within the unit control panel. For installation of the CT’s in
retrot applications, see document section titled, Installing
Spilt-Core CT’s on page 15 and Installing Rogowski Coil
CT’s on page 16.
Power Supply
A 24 VDC Power Supply is provided to power the M2M
Gateway. In the case of a unit ordered with Intelligent
Equipment, the power supply will be factory-installed in the
unit control panel. For installation of the power supply in
retrot applications, see document section titled, Installing
Power Supply on page 9.
Fuse Block
(Not on Gateway-on-the-Go, IE Express, or
WMC kits)
A Fuse Block is provided to provide over-current protection for
the Energy Management Module (EMM). Replaceable 5Amp
fuses are pre-installed in the Fuse Block. In the case of a unit
ordered with Intelligent Equipment, the Fuse Block will be
factory-installed in the unit control panel. For installation of the
Fuse Block in retrot applications, see document section titled,
Installing Fuse Block on page 10.
USB-to-Ethernet Adapter
For installations where a Local Area Network (LAN) connection
is to be used, a USB-to-Ethernet adapter is included in all
shipments. The adapter is necessary because the M2M
Gateway has a single Ethernet plug, which is connected to
the MicroTech III controller, and, therefore, unavailable for
connection to the LAN.
