Connecting directly to a panel
One Sensor can connect to one 3-phase electrical panel or
device or to three single-phase panels or devices. The
Sensor measures line-to-neutral voltage and is suitable for
up to 600 volt systems (346 VAC wye).
If you need a fusible disconnect or plan to power the
Sensor from the monitored panel, an auxiliary box
containing a transformer and fusible disconnect is
available.
Suitable, safe, easy-to-install CTs with a 0.333 VAC
secondary are available through Opto 22. See form #1938,
the
information.
0.333 VAC secondary, the Sensor can monitor voltage
and current directly from the main power load panel on
a building or facility. It can also monitor loads from
individual subpanels or electrical devices such as chillers,
boilers, compressors, elevators, and air handling units.

Communication
The OptoEMU Sensor uses standard computer networks and
protocols to send data to the online software service, which
displays energy use to authorized viewers over the Internet.
The OptoEMU Sensor communicates with these services over
a standard 10/100 Mbps Ethernet network or over an 802.11a,
b, or g wireless LAN (local area network). With two
Mounting and Wiring
If the OptoEMU Sensor is monitoring voltage and current
directly from a panel or device, it should be mounted right
next to it. Power for the unit is supplied by a standard 120 VAC
or 240 VAC wall outlet. If you need to power the Sensor from a
panel or device with higher voltage, also purchase the
auxiliary box with transformer and fusible disconnect.
WARNING: Follow all installation instructions in the OptoEMU
User’ s Guide to avoid serious or fatal injury or severe damage to
equipment. All electrical wiring to the unit must be done by a
licensed electrician.
independent Ethernet network
interfaces plus an independent wireless
interface, the unit gives you the
flexibility to monitor devices in hard-to-
reach areas and to set up networking
suited to your business.
Security on the wireless LAN includes
802.11i WPA2/AES, currently considered
the best wireless security, plus the older
WPA security standard for backwards
compatibility.
Data Storage
The OptoEMU Sensor can store data
internally. If communication with the
software service is lost, the unit stores
data until communication is restored.
