IMPORTANT SAFETY INSTRUCTIONS

This manual contains important safety instructions that should be followed during the installation and

maintenance of this product.

To reduce the risk of electrical shock, and to ensure the safe installation and operation of this product, the following safety symbols have been placed throughout this manual to indicate dangerous conditions and important safety instructions.

WARNING - A DANGEROUS VOLTAGE OR CONDITION EXISTS IN THIS AREA. USE EXTREME CAUTION WHEN PERFORMING THESE TASKS.

AVERTISSEMENT - UNE TENSION OU CONDITION DANGEREUSE EXISTE DANS CETTE ZONE. FAIRE PREUVE D’EXTRÊME PRUDENCE LORS DE LA RÉALISATION DE CES TÂCHES.

CAUTION - This procedure is critical to the safe installation or operation of the unit. Follow these instructions closely.

ATTENTION - Cette procédure est essentielle à l’installation ou l’utilisation de l’unité en toute sécurité. Suivre ces instructions de près.

NOTE - This statement is important. Follow instructions closely.

NOTE - Cette déclaration est importante. Suivre les instructions de près.

• All electrical work must be done in accordance with local, national, and/or international electrical codes.

• Before installing or using this device, read all instructions and cautionary markings located in the manual, and on the inverter, the batteries, and the PV array.

• Do not expose this unit to rain, snow or liquids of any type. This product is designed only for indoor mounting.

• To reduce the chance of short-circuits when installing or working with the inverter, the batteries, or the PV array, use insulated tools.

• Remove all jewelry while installing this system. This will greatly reduce the chance of accidental exposure to live circuits.

• The inverter contains more than one live circuit (batteries and AC line). Power may be present at more than one source.

• This product contains no user-serviceable parts. Do not attempt to repair this unit.

• Do not install 120 volt AC stand-alone inverters onto 120/240 volt AC multi-branch circuit wiring. This could pose a fire hazard due to an overloaded neutral return wire in this configuration.

• When stacking inverters, always connect the chassis of each inverter together using the chassis ground lug; otherwise, a hazardous voltage may be present between each chassis.

BATTERY SAFETY INFORMATION

• Always wear eye protection, such as safety glasses, when working with batteries.

• Remove all loose jewelry before working with batteries.

• Never work alone. Have someone assist you with the installation or be close enough to come to your aid when working with batteries.

• Always use proper lifting techniques when handling batteries.

• Always use identical types of batteries.

• Never install old or untested batteries. Check each battery’s date code or label to ensure age and type.

• Batteries are temperature sensitive. For optimum performance, they should be installed in a stable temperature environment.

• Batteries should be installed in a well vented area to prevent the possible buildup of explosive gasses. If the batteries are installed inside an enclosure, vent its highest point to the outdoors.

• When installing batteries, allow at least 1 inch of air space between batteries to promote cooling and ventilation.

• NEVER smoke in the vicinity of a battery or generator.

• Always connect the batteries first, then connect the cables to the inverter. This will greatly reduce the chance of spark in the vicinity of the batteries.

• Use insulated tools when working with batteries.

• When connecting batteries, always verify proper voltage and polarity.

• Do not short-circuit battery cables. Fire or explosion can occur.

• In the event of exposure to battery electrolyte, wash the area with soap and water. If acid enters the eyes, flood them with running cold water for at least 15 minutes and get immediate medical attention.

• Always recycle old batteries. Contact your local recycling center for proper disposal information.

1.0 INTRODUCTION

SWI Stacking Interface Cable Kit

The SWI Stacking Interface Cable is an accessory for SW and PS Series inverters. This cable allows the AC

output of two (identical) inverters to be connected in a series configuration, providing both 120 and 240 VAC, 60 Hz power for the loads. The AC input to the inverters is provided by the L1 and L2 legs of the utility grid (or 120/ 240 VAC generator) with L1 connected to the input of one inverter and L2 connected to the corresponding input of the other inverter (i.e., AC1 of both inverters).

Stacking is also an excellent choice for providing power to multi-wire branch circuits where stand alone

(120 VAC) inverters may require extensive rewiring within the building.

The SWI Stacking Interface Cable kit consists of:

• This Installation Guide

• One 42-inch stacking interface cable, complete with two 25-pin D connectors

CAUTION: Do not use a standard computer cable in place of the SWI stacking interface cable.
