3.0 Installation

3.1 Installing the MPX

Info: Installations should be performed by qualifi ed personnel, such as a licensed or

certifi ed electrician. It is the installer’s responsibility to determine which safety codes

apply and to ensure that all applicable installation requirements are followed. Applicable

installation codes vary depending on the location and application of the installation.
WARNING: This manual does not cover all the relevant safety instructions for your entire

MP/MPX system. Review the safety information on pages 1 and 2 of this manual. Refer

to the MP Owner’s Manual (PN: 64-0028) prior to installing the MPX extension.

CAUTION: The MPX/MP enclosures and the inverters are heavy. Remember to use proper

lifting techniques during installation to prevent personal injury.

3.1.1 Preparation

Before proceeding, read the entire Installation section to determine how you are going to install your

MPX extension. The more thorough you plan in the beginning the more time you will save. Proper

planning will also help you avoid common, costly mistakes.

Location

Info: When possible, Magnum Energy recommends that if you are installing only one MPX

it should be mounted to the left of the MP enclosure. Mounting the MPX on the right may

prevent you from adding certain manufacturers’ charge controllers in the future.

Only install your enclosure/inverter system in a location that meets the following requirements:
Clean and Dry - System must be mounted indoors in a relatively cool, clean, and dry environment.
Ventilation - If installed on the MP enclosure or MPX, the inverters pull in air through the intake

vents. In order to provide full output power and avoid over-temperature fault conditions do not cover

or block the MPX/MP enclosures’ ventilation openings, or install it in an area with limited airfl ow. At

the minimum, allow 3 inches of clearance to the left and right sides of the MPX/MP enclosures.
Close to the Battery Bank - Locate system as close to the batteries as possible. This ensures the

battery cable length is kept as short as possible. Long DC wires tend to lose effi ciency and reduce the

overall performance of an inverter. However, the MPX/MP enclosures, inverter, and any other equipment

that can spark (or that corrosion could damage) should not be installed in the same compartment/room

as the batteries or mounted where it will be exposed to battery gases. These gases are corrosive and

will damage this equipment; also, if these gases are not ventilated and if allowed to collect, they could

ignite and cause an explosion. Consult your battery supplier for proper installation requirements.

Info: Consult your inverter owner’s manual to determine the proper inverter-to-battery

cable size for the distance that is used. However, this cable must not be sized any smaller

than 0000 (4/0) AWG if the DC disconnect breaker in the MP enclosure will also be used

as the overcurrent device. If a cable smaller than 4/0 AWG is used, an appropriately sized

fuse must be installed to provide overcurrent protection to this smaller cable.
