1.3 – Limitations of Use

The Conext XW Pro or XW+ Inverter/Charger built into the SimpliPhi Power AccESS is not intended for

use in connection with life support systems or other medical equipment or devices.

1.4 – Inverter/Charger Programming Settings

The Schneider Electric Conext XW Pro Inverter/Charger and XW+ Inverter/Charger has a firmware

limitation that creates a potential issue with Lithium-Ion batteries: The Low Battery Cut-Out Voltage

(LBCO) setting is limited to 48V maximum. This value is below the recommended LBCO settings to

maximize cycle-life of most Lithium-Ion batteries including PHI 3.8 Batteries. Per the Warranty, a 48V

LBCO corresponds to 100% DoD and maintains a much more limited cycle life.

Until Schneider releases updated firmware to adjust this setting above 48V, this issue can be largely

mitigated by setting the “Recharge Volts” above the desired LBCO thresholds as outlined in Table 1.0

below. Therefore, systems that do not rely solely on renewable energy (i.e. grid tied systems, AGS systems)

will typically start charging the PHI 3.8 Batteries once the recharge voltage level is reached, preventing

further discharge of the PHI 3.8 Batteries and thus optimizing cycle-life. Systems that do rely solely on

renewable energy (i.e. no backup grid or AGS) and are using an XW+ inverter with dated firmware will most

likely discharge PHI batteries to the 48V / 100% DoD level, implying a 3,500 cycle life Warranty instead of

the 10,000 cycle life Warranty available to those systems maintaining the PHI batteries at 80% DoD.

1.5 – Explosive Gas Precautions

This equipment is not ignition protected. To prevent fire or explosion, do not install this product in

locations that require ignition-protected equipment. This includes any confined space containing vented

batteries, or flammable chemicals such as, natural gas (NG), liquid petroleum gas (LPG) or gasoline

(Benzine/Petrol).

Do not install in a confined space with machinery powered by flammable chemicals, or storage tanks,

fittings, or other connections between components of fuel or flammable chemical systems.

1.6 – FCC Information to the User

The Schneider equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against

harmful interference in a residential installation. This equipment generates, uses and can radiate radio

frequency energy and, if not installed and used in accordance with the instructions, may cause harmful

interference to radio communications. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause harmful interference to radio or television reception,

which can be determined by turning the equipment off and on, the user is encouraged to try to correct the

interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment to a circuit different from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.
