1.0 – Important Safety Information

CAUTION: THESE 14 THINGS WILL VOID THE PHI WARRANTY & DAMAGE THE

BATTERIES. READ IN FULL PRIOR TO BATTERY INSTALLATION

1.1 – Safety Instructions

1. Before using the unit, read all instructions and cautionary markings on the unit, the PHI 3.8

Batteries, and all appropriate sections of this manual.

2. PHI 3.8 Batteries must be fully charged before commissioning the AccESS unit (i.e. before turning

on connected loads). Failure to do so will Void the Warranty.

3. Use of accessories not recommended or sold by the manufacturer may result in a risk of fire,

electric shock, or injury to persons and will Void the Warranty.

4. Consult the Integration Guide for Inverter and Charge Controller settings for relevant warnings

and notices. All Integration Guides are posted on SimpliPhi’s Product Documentation web page

(https://simpliphipower.com/product-documentation/). Violating Warranty conditions specified in

those Integration Guides will Void the Warranty on the whole AccESS unit, not just the Schneider

Electric equipment.

5. Each AccESS unit contains three or four PHI 3.8 Batteries. Although each PHI 3.8 Battery

contains both an 80 Amp circuit breaker and an internal BMS with circuitry that protects the PHI

3.8 Battery cells from overcharge, over-discharge and excessive load amperage, the PHI 3.8

Batteries must always be installed with appropriate inverter charge controller settings and power

electronics to protect the PHI 3.8 from open PV voltage and other high voltage charging sources.

Do not attempt to replace existing power electronics without SimpliPhi’s written approval. Failure

to adhere to installation protocol will Void the Warranty.

6. Verify polarity at all connections with a standard voltmeter before 1) energizing the system and 2)

turning the PHI 3.8 80 Amp breaker “ON/OFF” switch to the “ON” position. Reverse polarity at

the PHI 3.8 Battery terminals will Void the Warranty and destroy the PHI 3.8 Batteries.

7. PHI 3.8 Batteries pose some risk of shock or sparking during the installation and initial wiring and

connection process. This is consistent with all other battery-based storage formats. Be sure to

turn the built-in 80 Amp breaker to the “OFF” position to minimize the risk of shock or sparks

during the installation and commissioning of the system.

8. To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition and

that wire is not undersized. Do not operate the AccESS unit with damaged or substandard wiring.

This will Void the Warranty.

9. Do not operate the AccESS unit if it has been damaged in any way during shipping or otherwise.

10. Only use a SimpliPhi approved LFP battery charger if ancillary charging is required before

installation, testing or troubleshooting. Failure to use a SimpliPhi approved LFP battery charger

will damage the PHI 3.8 Battery and Void the Warranty. Refer to the PHI 3.8 Manual for details

regarding SimpliPhi-approved ancillary charging equipment.

11. To reduce the chance of short-circuits, always use insulated tools when installing or working with

this equipment.

12. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with

electrical equipment.
