Ensure the Gateway tray is removed before making any feed-through connections on the Metered Lugs. See Gateway tray removal for details.
Without removing the Metered Lugs cover, insert L1 and L2 feed-through cables through the Metered Lugs dedicated for 200 A. Install L1 and L2 cables using a 1/ 4” Hex driver, torquing to 250 in-lbs (29 N-m).

Wiring whole-home Surge Protection Device (SPD)
The center terminals on the Metered Lugs are dedicated for whole-home SPD connections.
To directly terminate whole-home SPD connections on the Metered Lugs:

1. Insert SPD cables through the small terminals between L1 and L2 terminals.
2. Torque-down SPD cables using a #2 square or flat head screwdriver, torquing to 45 in-lbs (5 N-m).

WARNING: Risk of electric shock. Check that all circuits are de-energized before making any connections, including generation equipment such as solar inverters and storage batteries.

CAUTION: The SPAN Panel is only intended for use on 120/240 VAC split-phase electrical service.

• Connect line conductors for all circuits to the respective breaker.
• Connect neutral and ground conductors to their respective wire terminals.
• Once all conductors are connected and secured, check that there are no exposed conductors or stray wires.
• Clean up conductor routing to ensure no wires will be pinched when re-assembling each modular deadfront and overall deadfront.

CAUTION: Do not remove or modify factory-installed jumper cables and fasteners unless following specific instructions in this manual. Improper connections on factory-installed fasteners or cables may lead to Panel malfunction and damage. Such damage is not covered under the SPAN Panel Limited Warranty.

NOTE: Follow markings on Panel enclosure for specific ground bar positioning and orientation at each designated ground bar location.

NOTE: Keep track of circuit labeling in retrofit installations. This information is required during commissioning.

NOTE: SPAN is also compatible with most standard SPDs connected to a 2-pole breaker or installed on a 2-space slot. The SPD circuit must be marked as an essential circuit in the SPAN Installer App under Circuit Labeling. If using an SPD with usable circuits, be sure to only have essential items on those circuits (e.g., internet router, alarms, fire detection). Homeowners will not be able to turn this circuit off via the SPAN Home App.

NOTE: SPAN is not responsible for the performance of SPDs. Follow manufacturer installation guidelines for direct terminal wiring compatibility.

Communications wiring

Use minimum 300V rated, twisted-pair, copper conductors only for inter-devices signal wiring. Use shielded cables for CAN and RS-485 connections. Run no more than 328 ft (100 m) of cable length for Ethernet, CAN, and RS-485 wiring.

Wiring the Panel Controller
Every SPAN Panel has a Panel Controller that governs and enables smart features on the Panel. It is permanently fixed to the panelboard and requires its own neutral and ground connections (factory-installed). The SPAN Panel Controller powers the SPAN Panel enclosure-side LEDs and Gateway, while supporting external CAN, RS-485, auxiliary signal, and Ethernet connections.
Low voltage connections to additional hardware devices using CAN, RS-485, auxiliary signals, or external CTs are located beneath the Gateway tray. See Gateway tray removal.

Appendix A: Circuit breaker compatibility

SPAN has been evaluated per the UL Standard for panelboards for use with the branch breaker types below in Table A.1.

Informational Notes
National Electric Code (NFPA 70) does not prohibit the use of different branch circuit breakers in panelboards provided it does not violate the listing of any equipment. NEC article 110.3(B) states “Equipment that is listed, labeled, or both shall be installed and used in accordance with any instructions included in the listing or labeling.”
The Standard for Molded-Case Circuit Breakers (UL 489) does not require listing circuit breakers for use in specific panels, nor does this standard cover panelboards. Such testing is covered by the UL Standard for panelboards (UL 67), which does require the panelboard to be listed with specific breaker types. SPAN is certified to the UL 67 Standard via a Nationally Recognized Testing Lab (NRTL) for use with the branch circuit breakers below. This is reflected in this installation information as well as marked on the product itself.
Compatible branch breakers are listed on following pages.

NOTE: SPAN Panel is not compatible with Eaton BRL type branch breakers. Ensure secure attachment of branch breakers at the panelboard busbar stab and heel to prevent any wobbling or loose connections.

Appendix B: PowerUp and PCS

The SPAN Panel with PowerUp is equipped with a power control system (PCS) to prevent the overloading of its mains conductors. The PCS functions are enabled by default whenever SPAN PowerUp™ is turned on by the SPAN Authorized Installer™ and cannot be modified or deleted by a user once set. SPAN PowerUp is enabled during installation commissioning using the SPAN Installer® App. Note that modifications, including disabling the PCS function, can only be done by a SPAN Authorized Installer after requesting a password from SPAN to unlock the PowerUp settings in the SPAN Installer App. The PCS function operates independent of other SPAN PowerUp features, such as appliance prioritization.

Where the main breaker in the SPAN Panel is used on the service or feeder overcurrent protective device, the SPAN PCS is suitably rated to provide branch circuit overcurrent protection for the feeders or service conductors connected to the integral main breaker. The controlled current setting’s (the PCS Setpoint’s) continuous current rating shall not exceed the rating of conductor ampacity terminated to the main lugs of the SPAN Panel. The SPAN Panel PCS does not include any additional PCS operating modes (such as ESS operating modes) other than those outlined in this manual. However, the SPAN Panel PCS does not restrict the PCS operation of any other device which is connected to the SPAN Panel or service.

Compliance Info
SPAN Panel is listed both as a panelboard to UL 67 and as Energy Management Equipment to UL 916. SPAN Panel installations must meet applicable requirements in NFPA 70®, National Electrical Code® (NEC®) and the installation instructions provided by SPAN. All commissioning processes and settings, including PowerUp settings, must be performed by a SPAN Authorized Installer as described by SPAN in the installation instructions, and in the SPAN Installer App.
Proper operation of SPAN’s PowerUp energy management functions are dependent upon the Panel being commissioned with the correct setpoint, including the rating of the main overcurrent protection device(s) supplying SPAN Panel. See SPAN Panel installation instructions for additional warnings and requirements.

WARNING: Configuration of SPAN PowerUp PCS settings, or changes to these settings, shall be made by qualified personnel only. Incorrect configuration or setting of the power control settings may result in unsafe conditions. All sensors used for PCS are integrated into the Panel and are not user-serviceable.

PCS Requirements
Where the SPAN Panel EMS/PCS functions have been enabled, in no cases shall the PCS setpoint exceed the rating of the overcurrent protection device, protecting the conductors connected to the main lugs of the SPAN Panel.
Where PCS functions are enabled for the SPAN Panel, the sum of the maximum currents from all power sources connected to the SPAN Panel’s busbars shall be less than or equal to the PCS continuous current rating.
Where the SPAN Panel EMS/PCS functions have not been enabled, and the Panel supplies continuous loads or any combination of continuous and noncontinuous loads, the rating of the overcurrent device supplying the panel shall not be less than the noncontinuous load plus 125 percent of the continuous load.

PCS Setpoint (A) (Circuit Breaker Rating)	Continuous Current Rating (A)	Max Power Source Current (A)
100	80	80
125	100	100
150	120	120
175	140	140
200	180	160

CAUTION: All PCS controlled busbars or conductors shall be protected with suitably rated overcurrent devices appropriately sized for the busbar rating or conductor ampacity.

NOTE: Where the SPAN Panel EMS/PCS functions have been enabled, the maximum operating currents in controlled busbars or conductors are limited by the settings of the power control system (PCS) and may be lower than the sum of the currents of the connected controlled loads or power sources. The settings of the PCS controlled currents may be used for calculation of the design currents used in the relevant sections of NEC Articles 690, 705, and 220.
