MNECSW E-Panel Instructions Removing the E-Panel cover To remove the E-Panel cover Remove the four screws on the front and the four screws on the left side. The cover will now pull straight out toward you. To Re-install reverse the steps shown above. If you have a slider installed to tie the breakers together as a bypass switch, ensure that the breakers are in the correct position (all up or all down) and that the slider engages the handles on the breakers.
MNECSW E-Panel Instructions Installing the XW-SCP To install the XW-SCP to the front of the E-Panel remove the rectangular knockout at the lower left corner of the E-Panel. Remove any sharp edges. Route the Xanbus cable from the connection on the inverter to the connection on the XW-SCP and install the terminator if appropriate. A terminator is required at each end of the network. Refer to the documentation that came with your XW-SCP.
MNECSW E-Panel Instructions Installation Considerations While the E-Panel can greatly simplify the wiring of an inverter system, the installation and wiring of electrical systems is a complex task and should only be attempted by qualified installation personnel. The E-Panel is a Type 1 enclosure intended to be mounted in a dry location, protected from rain, snow etc. The NEC requires clearance around the enclosure and 36" free and clear of obstructions in front of the installation.
MNECSW E-Panel Instructions Installation Tools Required: Drill and drill bits for pilot holes #2 Phillips screwdriver Slotted screwdriver (A torque driver is recommended for all electrical connections) Wrench or socket set for mounting Wrench or socket set for DC Terminals Wire strippers Needle-nose pliers Other materials needed for installation: (these will vary based on system options) Strain Reliefs, Hardware for Mounting E-Panel, Inverter and Backplate Wire/cable for AC and DC connections Optional eq
MNECSW E-Panel Instructions Installation Continued Installation begins with selecting a location that is dry, accessible and able to support the weight of the system. Choose a location that minimizes wire lengths especially the battery cables. Use 2" long1 /4" or larger lag screws Use 2" long1 /4" or larger lag screws Drywall not shown Example: Conext SW E-Panel with backplate wall mounted Above, the E-Panel and inverter are mounted to the wall with the backplate.
MNECSW E-Panel Instructions Installation Continued Use 3 1 /2" or longer 1 /4" lag screws 2X4 approximately 32-3/4" Drywall not shown Example: Wall mounting the Conext SW E-Panel and Conext SW Inverter Above the E-Panel and inverter are mounted to the wall without the backplate. In this installation 2X4s were used to span the studs. This helps to ensure a secure installation. Once the system is mounted on the wall the final connections can be made.
MNECSW E-Panel Instructions Danger! DC Wiring Potentially hazardous voltages may be present. Even at low voltages batteries can produce incredibly large currents. Ensure that all sources of power are disconnected. Tensions potentiellement dangereux peuvent être présents. Même à de faibles tensions batteries peuvent produire incroyablement grands courants. Veiller à ce que toutes les sources d'alimentation sont débranchés. E-Panel Busbars Inverter Battery Connections Inverter Battery connections.

MNECSW E-Panel Instructions AC Wiring Danger! Potentially dangerous voltages may be present. Ensure that all sources of power are disconnected. Des tensions potentiellement dangereuses peuvent être présentes. Veiller à ce que toutes les sources d'alimentation sont débranchés. These breaker locations may be used for AC or DC distribution or both if proper isolation is provided. Refer to the wiring diagrams for typical applications. Breakers sold separately.
MNECSW E-Panel Instructions Single Inverter with AC Bypass Above: AC wiring for a single inverter with bypass switch. Use a minimum of 8 AWG wire for a 50 amp bypass or a minimum of 6 AWG wire for a 60 amp bypass. The ground wire should be at least the same gauge as the largest wire used. When the slider is in the "UP" position Inverter power will be at the AC Output terminal blocks. When the slider is in the down position Grid/Gen power will be at the AC Output terminal blocks.
MNECSW E-Panel Instructions Single Inverter without AC Bypass Above: AC wiring for a single inverter without bypass switch. Use a minimum of 8 AWG wire. The ground wire should be at least the same gauge as the largest wire used. Torque all connections according to the chart in Appendix A. Re-torque the circuit breaker connections after one hour. Do not skip this step. The copper wire will cold flow after the initial tightening and may become loose creating a potential hazard.
MNECSW E-Panel Instructions MNSW4024-CL1 50 With AC Bypass Single Inverter with AC Bypass Above: AC wiring for a single inverter with bypass switch. Use a minimum of 8 AWG wire for a 50 amp bypass or a minimum of 6 AWG wire for a 60 amp bypass. The ground wire should be at least the same gauge as the largest wire used. Torque all connections according to the chart in Appendix A. Re-torque the circuit breaker connections after one hour. Do not skip this step.
MNECSW E-Panel Instructions Important! When stacking inverters make a neutral connection from each inverter's Neutral input to the main distribution panel Neutral bus and make a neutral connection from each inverter's Neutral output to the load distribution panel Neutral bus.

MNECSW E-Panel Instructions Slider Kit Installation To install the slider kit: The Slider kit comes with (2) 8-32 X 3/4" screws, (2) 8-32 plain nuts, (2) 3/1 6" nylon spacers, (1 ) slider and, (2) 8-32 lock nuts. Install the screws from the inside of the cover and secure with the plain nuts. Place the spacers on the screws as shown. Place the slider on the screws on top of the spacers. Secure with the lock nuts by tightening the nuts until they are just firm.
MNECSW E-Panel Instructions Pre-Wired and Dual Systems Dual system on Backplates. Optional equipment shown. On Pre-Wired systems with Classic Charge Controllers, the controller ships disconnected in its own box packed in with the E-panel. All the wiring for the Classic is pre-cut, stripped and in place. All that needs to be done is to secure the Classic with the conduit nipples supplied, add any additional support desired and connect the pre-cut, marked wires.
