Safe - Keep any ﬂ ammable/combustible material (e.g., paper, cloth,
plastic, etc.,) that may be ignited by heat, sparks, or ﬂ ames at a
minimum distance of 61 cm (2’) away from the inverter.

WARNING: The MMS-E Series inverter/charger is not
an ignition-protection rated device and should not be
installed in any location that requires ignition-protected
equipment. To prevent ﬁ re or explosion, do not install
the MMS-E in any area with extremely ﬂ ammable liquids
like gasoline or propane; or, in an area that contains
connections between components of a fuel system.

lose to the battery bank - As with any inverter, it should be located

as close to the batteries as possible. Long DC wires tend to lose
efﬁ ciency and reduce the overall performance of an inverter. However,
the unit should not be installed in the same compartment as the
batteries or mounted where it will be exposed to gases produced by
the batteries. These gases are corrosive and will damage the inverter.
Also, if these gases are not ventilated and allowed to collect, they
could ignite and cause an explosion.

Accessible - Do not block access to the inverter’s remote control and
accessory ports. Also, allow enough room to access the AC and DC
wiring connections, as they will need to be checked and tightened
periodically. See Figure 2-3 for the MMS-E Series’ inverter dimensions.

Mounting orientation - The MMS-E Series inverter/charger should
only be mounted on a horizontal surface (shelf or table) or a vertical
surface (wall or bulkhead) either right-side up or up-side down, as
shown in Figure 2-2. This is to prevent the inverter’s vents from facing
down. The inverter must be mounted on a non-combustible surface*,
and this surface and the mounting hardware must be capable of
supporting at least twice the weight of the inverter. After determining
your mounting position, either use the base of the inverter’s chassis
as a template to mark your mounting screw locations, or refer to
the physical dimensions as shown in Figure 2-3. Drill pilot holes into
the mounting surface, and then mount the unit with the appropriate
mounting hardware.

If this unit is used in a mobile application, you may want to place
ﬂ exible washers or bushings between the mounting surface and the
inverter’s mounting ﬂ anges to reduce vibration.

After the inverter has been properly mounted, proceed to the DC
Wiring section.

* Noncombustible surface - A surface made of material that will not
ignite, burn, support combustion, or release fl ammable vapors when
subjected to fi re or heat. For the most part, these materials are
largely comprised of inorganic materials such as stone, steel, iron,
brick, tile concrete, slate and glass. Common building materials such
as gypsum board as well as any paint, wall covering, and certainly
wood will not pass.
