Legal
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. Operation is subject to these conditions:
1. It may not cause harmful interference.
2. It must accept any interference received, including interference that may cause undesired operation. If it is not installed and used as per the instructions, it may cause interference which is harmful to wireless communications. There is no guarantee that interference will not occur in a particular installation. If it does cause interference we recommend: reorienting or relocating the receiving antenna, or increasing the separation between the device and the receiver.

Instructions
Wiser Energy can support split-service systems up to 400 A (200 A per panel). Sensor cable extensions or additional current sensors may be needed in order to connect a second panel to the Wiser Energy monitor. Sensor extension cables can support distances up to 80 feet. Please contact customer support to purchase accessories.
Please note that these instructions are for split-service systems and do not apply to dual-panel systems consisting of a main panel and a subpanel. Wiser Energy can work with subpanels without need for additional sensors.
01 Open the middle port
Already have Wiser Energy installed? Skip to step 2 to remove power to the Wiser Energy monitor before opening the middle port.
Using a flathead screwdriver, pry open the cap on the middle port of the Wiser Energy monitor. This will be used to connect the second set of sensors for your additional panel.
02 Turn OFF power
Installation of the Wiser Energy System requires removal of all power. Be sure to provide an alternate light source before beginning the installation procedures. Do not begin the installation procedures until all power is completely removed from the equipment including any alternate power sources.
1. Turn OFF the main feeder disconnects that supply power to both electrical panels, or if the installation uses the revenue meter for isolation, arrange for the utility provider to remove power. If a main feeder disconnect is not present and the revenue meter cannot be used as an isolation device, contact the utility company for removal of power.
2. Turning OFF only the main circuit breaker is insufficient to remove power completely from the panel. Line side connections will still be live.
3. Apply the appropriate lockouts to the disconnecting means.
4. Turn OFF all alternate power sources connected to the equipment.
03 Remove panel covers
1. Apply appropriate PPE.
2. Remove the cover screws and remove the load center cover from each panel.
3. Measure the voltage from each line to neutral and from line to line to confirm that all power is OFF.
04 Find a spot for the Wiser Energy monitor
Already have Wiser Energy installed? First open your monitor’s middle port according to step 1, then skip to step 8.
The Wiser Energy monitor is designed to fit within one of your panels in order to monitor a home’s energy consumption.
Note: If there is no open space available, use an external enclosure following NEC® and local standards.
05 Install the antenna
Using the back of a screwdriver, punch out the knockout cover in the electrical panel. Then, insert the antenna.
DANGER
HAZARD OF ELECTRIC SHOCK EXPLOSION, OR ARC FLASH
Maintain 1 in. (25mm) minimum separation between the monitor and antenna extension assembly to load center parts (bus, stabs, circuit breakers, and power wires).
Failure to follow these instructions will result in death or serious injury.
06 Connect
In the same panel the Wiser Energy monitor is located, connect the power cable, antenna, and current sensors to the monitor. Be sure to insert the sensor into the outer port.
07 Clamp sensors around service mains
As a precaution, first plug the sensors into the Wiser Energy monitor.
In the panel where the Wiser Energy monitor is located, clamp the current sensors around the service mains so that both Wiser Energy labels face the same direction. The direction of the labels on the sensors should face the power source. Once placed in the final orientation, push the sensor lock in until you hear a click.
As a precaution, first plug the sensors into the Wiser Energy monitor.
08 Connect second set of sensors to middle port
Connect the second set of sensors to the middle port on the monitor.
09 Clamp sensors around service mains in second panel
In the second panel, clamp the second set of sensors around the service mains so that both labels are facing the same direction. The direction of the labels on the sensors should face the power source. Once placed in the final orientation, push the sensor lock in until you hear a click.
What if the sensor cables are not long enough?
Contact customer support to get sensor extension cables, which can support distances up to 80 feet.
10 Connect the power wires
Already have Wiser Energy installed? Skip to step 11.
(compatible with Square D 15 – 30 A thermal magnetic circuit breakers).
Dedicated Circuit Breaker Method
In the panel where you placed your Wiser Energy monitor, add a new Square D brand two-pole 15 – 20 A circuit breaker into the load center. With circuit breaker OFF, connect the black power wire to one circuit breaker terminal and connect the red wire to the other terminal.
Two Wire Rated Lug Method
Existing Square D brand 15 – 30 A thermal magnetic two-pole circuit breakers in the load center have terminals that can accept two conductors. With the circuit breaker OFF, use half of the clamp plate for load wire and the other half for Wiser Energy power wire.
Pigtail Wire Method
With the circuit breaker OFF, create a splice connection to the two-pole circuit breaker following the NEC and circuit breaker manufacturer guidelines for splice connector type and wire size.
Note: For all three methods, attach a white wire to an appropriately sized terminal on the neutral bus bar.
11 Close the panel covers
Replace the panel covers carefully to ensure that there is no pressure on the current sensor clamps that would cause them to open. Label the Wiser Energy circuit breaker with the included sticker.
12 Turn power on, wait for chime
Once both panels are closed, restore power to the panels and listen for one minute for one of the following sounds:
Visit help for troubleshooting.
Success Chime: Installation was successful!
Repeating Beep: There is an installation problem. Check cable connections.
No Sound: The Wiser Energy monitor cannot start. Check power cable connections.
13 Use the app to complete setup
Install the Sense app. Tap “Get Started” and follow the on-screen instructions. The app will guide you through the Wi-Fi setup and account creation process.
