GS-IOB-120/240VAC

Input/Output/Bypass Assembly

Purpose

This document provides information on how to install the Input/Output/Bypass

Assembly needed for a 120/240 Vac configuration using an OutBack GSLC

(GS Load Center) enclosure.

This product allows manual switching between a single Radian Series

Inverter/Charger and an AC source, facilitating maintenance and power

continuity. It is intended to be installed within the GSLC or one of its variants.

Scope

This document covers how to install the input, output, and bypass circuit

breakers and mechanical interlock onto the GSLC.

Wiring requirements are

site-specific and will vary by installation.

Certain steps may be omitted or

altered if they do not apply to a particular installation.

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.

Requirements

OutBack Power’s GS-IOB-120/240VAC is intended as a component for OutBack

listed UL508A or UL1741 Industrial Control Panels, specifically the GSLC variants.

It is intended for indoor use only. This equipment is to be installed by qualified

personnel only. Refer to the GS Load Center Installation Manual for complete

installation instructions.

Grounding Instructions

The enclosure for the GS-IOB-120/240VAC should be connected to a grounded,

permanent wiring system. The AC and DC circuits are not bonded to the

enclosure chassis. System grounding, when required by the National Electric

Code, ANSI/NFPA 70 or the Canadian Electrical Code, CSA C22.1, is the

responsibility of the installer. All installations should comply with all national and

local codes and ordinances.

The equipment ground is marked with this symbol:

GS-IOB-120/240VAC Installation Instructions Installing the Circuit Breakers and Mechanical Bypass Assembly The simplest method to install these devices is to remove the main circuit breaker bracket from the GSLC first. To remove the main bracket: 1. Remove the front cover (sometimes called the “front door”) of the GSLC. Open the door to 90 degrees and lift up about 1/2” to disengage it from the GSLC (see Figure 3). 2. Remove the interior cover (sometimes called the “dead front”) of the GSLC.

GS-IOB-120/240VAC Installation Instructions Once the main bracket has been removed, install the circuit breakers and mechanical bypass according to the following steps. 1. 2. 3. 4. 5. Place each circuit breaker behind the bracket and orient it so that the pole with the switch is on top and the numbers read correctly. Center the device so that the raised area protrudes through the bracket. Place the red bypass brackets over the screw holes for the top three circuit breaker poles.

GS-IOB-120/240VAC Installation Instructions Basic AC Wiring The GS-IOB-120/240VAC comes with six red, six black, and one white wire that are labeled according to their intended electrical connection. It also comes with an unlabeled green wire, and four unlabeled short red and black wires. If the preceding steps are followed, as well as the drawing in Figure 5, these wires will have sufficient length to make the intended connections.

Figure 5 Basic AC Wiring At this stage, the installation is complete. The interior cover must be re-installed using the six screws and star washers previously removed. The front cover can then be re-installed. Use the illustrations in Figure 3 on page 4 for reference.
