MNE-240 E-PANEL INSTRUCTIONS
Figure 1, MNE-240 Series E-Panel Features
3.0 Installation
Before installing, read the entire installation section to determine how you are going to install
your E-Panel. The more thorough you plan in the beginning, the better your overall system needs
will be met.
A basic system diagram for the MNE-240 Series E-Panel is shown in Figure 2, MNE-240 Series
E-Panel System Wiring Diagram. This diagram should be reviewed to assist you in planning and
designing your installation.
Info: Installations should be performed by qualified personnel, such as a licensed or
certified electrician. It is the installer’s responsibility to determine which safety codes
apply and to ensure that all applicable installation requirements are followed.
Info: It is easier to install and wire any additional accessories (i.e. breakers for charge
control, the inverter, etc.) while the E-Panel is still lying horizontal on a table. Do as much
as possible before mounting the E-Panel on the wall.
3.1 Door Configuration
The standard E-Panel ships with breakers on the right side and with a left hand hinge. The
door will open to the right over the breakers. If for some reason you need the breakers on the
right, but the door to open to the left, then you can purchase the left hand door (part number
MNEleftdoorSTM-240).
Info: The circuit-breakers can be moved from the right side and reassembled on the left
side of the chassis. Even though this is possible, it is not advised. Moving the breakers is
very time consuming and the bypass switch will need to be re-positioned and rewired. It
is much more efficient to so spend the time before the installation to pre-determine and
order the correct side (left hinge or right hinge door).
3.2 Knockout Preparation
Info: See Figure 3 for the location and dimensions for the knock-outs on the MNE-240
Series E-Panel.
Think about all the different wiring required and remove the appropriate knockouts before
mounting the E-Panel. Knockouts for breakers and outlets are best accomplished using a straight
bladed screw driver and hammer. A hacksaw blade is another way to cut them out.
Determine the knockout uses for:
• wiring from the E-Panel to an AC sub-panel
• wire runs from utility and/or a generator to the E-Panel
• battery cable wiring from the battery bank to the E-Panel
• additional wiring from any external DC source (PV, Wind or Hydro) to the E-Panel
• small signal wiring (battery sensors, battery monitoring, auto gen starting)
• attaching lightning arrestors
• charge control wiring
