Page 5: Introduction
Introduction Audience This manual provides instructions for installation, setup, and operation of the product. These instructions are for use by qualified personnel who meet all local and governmental code requirements for licensing and training for the installation of electrical power systems with AC and DC voltage up to 600 volts. -
Page 6: Components
Introduction Components The primary component in the ICS Plus system is the DC combiner box. This combines up to six PV source circuits and provides an overcurrent protective device (OCPD) for each circuit. The AFCI device is located here. The combiner provides a local disconnecting means. It also provides a contactor for PV rapid shutdown functionality to de-energize PV circuits within 10 feet of the PV array. - Page 7 Introduction PV Array Combiner ≤ 10 Feet Fuses AFCI ROOF Contactor HOUSE EXTERIOR Battery-Based Inverter HOUSE INTERIOR Battery Charge Controller Bank Utility Meter BKR-CTRL-DC Combiner Box Contains OCPD, AFCI, main contactor, PV Combiner Disconnect Includes local disconnect to de-energize PV circuits within 10 feet of the array ...

Page 11: Functions
Functions Arc Fault Circuit Interruption In a PV system, an electrical arc occurs when current bridges a gap between conductive surfaces. Gaps can occur due to conductor damage, or can be caused by inadequate system connections. An “arc fault” is a safety concern for several reasons: ... -
Page 12: Arc Fault Self-Test
Functions Arc Fault Self-Test The arc fault function can be manually tested. The arc fault self-test mimics the conditions of an arc fault. The combiner and RSI give the same indications as described on page 11. To perform the arc fault self-test: Ensure the system is functioning and all indicators are normal. -
Page 13: Installation
Installation This section assumes the use of the combiner, the RSI, the BKR-CTRL-DC and the RTB. The combiner box is a required part of all ICS Plus systems. All examples in OutBack literature show one or more combiners in use, including the ICS Plus Quick Start Guide. The RSI is required for all ICS Plus systems utilizing the PVRSS function. -
Page 14: Connection Information
Installation Connection Information Combiner The combiner box can take input circuits from up to six PV subarrays. It provides a single PV output which is connected to the load center and one pole of the RTB. See Figure 4 on page 15. ... - Page 15 Installation via load center 24V RSI Supply PV RSI Safe 24V Combiner Supply Breaker Trip PV Arc Fault Trip Sense Breaker RSI Safe Breaker-Trip Coil PV to RTB Figure 4 Block Diagram 900-0184-01-00 Rev A...
- Page 16 Installation Optional Connections The RSI has several sets of auxiliary terminals. Terminal J6 has a factory-installed jumper. J3 , J4 , and J5 do not. The terminals can be wired to alarms or switches to send or receive status messages. J3: AUX RSI Command/Status Output Dry contacts which report RSI status.

Page 17: Other Applications
Other Applications Alternative System Requirements The ICS Plus can be used in systems with varying requirements, or with third-party equipment. Some systems may only need certain ICS Plus components, rather than the entire system. This may depend on the applicable codes. NOTE: All systems depicted here assume the use of a PV combiner with AFCI protection required. -
Page 18: Positive Ground
Other Applications Positive Ground The ICS Plus can be used in positive-grounded installations. For these solutions, the ungrounded PV negative (–) conductors should be connected to the fuse holders. The grounded PV positive (+) conductors should be connected to the white bus bar. Other connections, such as the combined PV output, should be similarly reversed. -
