2. Cool: Ambient air temperature between 23°F and 104°F (-5°C and 40°C)
3. Ventilated: Allow at least 6 in (150 mm) of clearance above and below and at least
1 in (25 mm) on each side for proper air flow.
4. Safe: Do not operate in a shared compartment with batteries or any flammable
substances, (e.g.: gasoline)
IMPORTANT:
To avoid fire, do not cover or obstruct ventilation openings.

RECAUTIONS
All electronic circuits may be damaged by static electricity. To minimize the likelihood of
electrostatic damage, discharge yourself by touching an electrical ground (e.g.: copper pipe) prior
to handling the unit and avoid touching components on the circuit boards. The risk of electrostatic
damage is highest when relative humidity is below 40%.

OUNTING
Mounting is optional for the VertaMax; however, the environment must be dry and protected from
water.
1. The VertaMax can be mounted on a vertical or horizontal surface. If mounted
vertically, the unit should be oriented such that neither end is at the top so foreign
material cannot settle into the unit.
2. Install four user-supplied fasteners through the four inverter mounting slots and
into the mounting surface.
3. Tighten all the fasteners to ensure the inverter cannot slide in any direction.
WARNING:
Do not mount on flammable surface material.

ROUNDING
The VertaMax is designed to work with grounded electrical systems by using a copper wire to
connect the grounding terminal on the VertaMax enclosure to earth ground or chassis ground.
The grounding terminal (if applicable) is located on the DC Input end of the inverter.
•
Vehicle installations: Connect to the chassis of the vehicle.
•
Boats installations: Connect to the boat’s grounding system
•
Fixed land based installations: Connect to earth ground
Do not connect the system negative conductor to this terminal. NEC requires the use of an
external ground fault protection device (GFPD). The system electrical negative should be bonded
through a GFPD to earth ground at one (and only one) location. The grounding point may be
located in the solar/wind circuit or the battery circuit.

ONNECTIONS
WARNING:
Electrical installations must meet local and national wiring codes, and should be
performed by a qualified electrician.
WARNING:
Do not connect the inverter and another AC source (such as a generator or utility
power) to the AC wiring at the same time.
WARNING:
Do not connect the inverter to an AC branch circuit that has high-power consumption
loads. It will not operate electrical appliances that consume more than the units rated watts.
WARNING:
Loose connectors result in excessive voltage drop and may cause over heated wires
and melted insulation, which can lead to electrical fires.
WARNING:
Reverse polarity connections (positive to negative) will blow internal fuses in the
inverter and may permanently damage the Inverter.
IMPORTANT:
In addition to the protection provided by the Inverter’s internal fuses, NEC requires
a 50-amp UL-listed fuse in the battery’s positive DC cable as close to the battery as possible.
