Important Safety Instructions

WARNING

This chapter contains important safety and operating instructions for the Sine Wave Plus Long DC Conduit Box (all models). Read and keep this Installation Guide for future reference.

1. Installations of this equipment should only be performed by skilled personnel such as qualified electricians and certified Renewable Energy (RE) system installers to ensure adherence to the local and national electrical codes applicable in your installation. For a list of Xantrex Certified RE dealers, please visit our website at www.xantrexREdealers.com.

2. Before installing any components, read all instructions and cautionary markings on the Long DC Conduit Box, the batteries, and all appropriate sections of this guide.

3. The Long DC Conduit Box is designed to be permanently connected to your Sine Wave Plus inverter to prevent accidental exposure to shock hazards.

4. Do not expose the Long DC Conduit Box to rain, snow, or spray. To reduce risk of fire hazard, do not cover or obstruct the ventilation openings.

5. Do not install the Long DC Conduit Box in a zero-clearance compartment. The Sine Wave Plus inverter that is attached may overheat. Minimum

clearance for ventilation around unit must be 12 inches (305 mm) at the end and the top.

6. 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 inverter with damaged or substandard wiring.

7. To reduce the risk of electrical shock, disconnect both AC and DC power from the system before attempting any maintenance or cleaning or working on the Long DC Conduit Box.

8. The Long DC Conduit Box is provided with an equipment-grounding bar that must be connected to the inverter equipment ground and the system ground.

9. Do not store any flammable materials near the primary system panel.

Safety

Explosive gas precautions

1. Working in the vicinity of lead-acid batteries is dangerous. Batteries generate explosive gases during normal operation. Therefore you must read this guide and follow the instructions exactly before installing the DCCB-L.

2. To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and the manufacturer of the equipment in which the battery is installed.

Certifications

CSA certified to the following standards:

• UL 1741-2001 First Edition, and

• CSA C22.2 No. 107.1-01

Introduction

Chapter 1, “Introduction” provides basic information about the design and purpose of the Sine Wave Plus Long DC Conduit Box.

The following topics are covered in this chapter.

Introduction

The Sine Wave Plus Long DC Conduit Box (DCCB-L) connects to the DC side of the inverter and accepts DC conduit runs. The conduit box provides protection to the DC cables connected to the inverter and provides a centralized location for the DC circuit breakers and PV Ground Fault Protection (GFP) breakers. It is also designed to incorporate cabling from up to two Multi-function DC Charge Controllers, such as the Xantrex C-Series Charge Controllers, and cabling from a battery meter, such as the Xantrex Battery Status Meter.

The Long DC Conduit Box is available in three different configurations.

•The DCCB-L Basic provides an internal ground bar only and space to add additional circuit breakers; three large and six small.

•The DCCB-L-175 includes a 175 amp GJ, F-Type, circuit breaker, a DC negative bus bar and 500A/50 mV shunt, battery cables (1 set) and a ground wire connected to the ground bar.

•The DCCB-L-250 includes a 250 amp GJ, F-type, circuit breaker a DC negative bus bar and 500A/50 mV shunt, battery cables (1 set) and a ground wire connected to the ground bar.

For expandability, the Long DC Conduit Box is designed so that a second DCCBL (any model) can be added on for additional breaker spaces, wiring, room and controller mounting spaces. Dual configurations have been certified to meet UL1741-2001 (First Edition) standards when using the field-installable accessories as listed page 1–6.

Blockoff Plates

Upper and Lower Blockoff Plates are included to enclose the open portions of the Long DC Conduit Box chassis. In the event that an inverter is removed, the Blockoff Plates secure the enclosure to prevent accidental contact with any AC power within the Long DC Conduit Box.

Remove the Blockoff Plate (upper or lower) from its position for the inverter used in your installation. The Blockoff Plates will not be needed at all in a dual SW Plus inverter installation.

See “Installing or Removing the Blockoff Plates” on page 2–6 for additional information.

Important:

single-inverter systems to use the upper mounting location for the inverter. Mounting an inverter in the lower mounting position for a single-inverter system will required sitefabricated cables.

The cable lengths provided in the DCCB-L-175/L-250 were designed for

WARNING: Shock Hazard

Be sure to disconnect all DC and AC power before removing the inverter and installing the blockoff plate.

Introduction

Options/Accessories

The following CSA-approved accessories are available through Xantrex to expand or monitor the DC side of the system.

• C-Series Multi-function DC Controllers (C35, C40, C60)

• Charge Controller Installation Package (CC PCK)

• PV Ground Fault Protection CF Breakers (PVGFP-CF-1, PVGFP-CF-2, PVGFP-CF-3, PVGFP-CF-4)

• GJ-F Series Flag Style Circuit Breakers 175A or 250A (without wiring) (GJ175F, GJ250F)

• GJ Series Flag Style Breakers 175A or 250A (with battery cables to connect second inverter) (GJ175F-PCK, and GJ250F-PCK)

• Dual-pole or Triple-pole GJ Flag Terminal Bus bars (GJ-FT2, GJ-FT3)

• CF Breaker Mounting Plate (CFMP)

• 60 Amp CF Series Circuit Breakers for loads (CF60)

• Power Distribution Blocks 6:1 and 12:1 (PDB-6 or PDB-12)

• Battery Status Meter (TM500A-NS without shunt) or (TM500A with shunt)

• Battery Temperature Sensors (BTS)

• Battery Cables for adding a second inverter (BC-L2-175 or BC-L2-250). These battery cables are the same as those included with the appropriate breaker with the GJF175-PCK or GJF250-PCK.

• DC Negative Bus Bar (DCBUSBAR)

Important:

configuration. Other components may be used, but may not allow continuous operation of the SW Plus Inverter and should be approved by the AHJ.

The components shown in this section are to be used in a DCCB-L-RE

Charge Controllers or Diversion Load Controllers

If charge control or diversion control is required, spaces are provided for mounting up to two DC controllers on the top of the DCCB-L chassis. Xantrex offers the C-Series Multi-function DC Controller to provide either charge control or diversion control.

Charge controllers not purchased from Xantrex may be used also, but might not fit the mounting holes on the top of DCCB-L. If this occurs, the non-Xantrex supplied charge controllers will need to be mounted somewhere off the DCCB-L chassis.

Any charge controllers used on this component (Xantrex and Non-Xantrex) should not exceed 60 A each (120 A total).

If more charge controllers are required, then it may be desirable to have two DCCB-Ls (any model combination) installed in a dual-configuration.
