## DESCRIPTION 

_groov_ EPIC® I/O mounting chassis are designed to hold an intelligent _groov_ EPIC processor, power supply, and I/O modules. 

Since _groov_ analog and discrete I/O modules all have the same footprint, these modules can all be mixed on the same chassis. Field devices are wired directly to the top-mounted connectors on the 

modules. The module and chassis design allows modules to pivot into a specific mounting positions on the chassis. 

_groov_ EPIC chassis are available in three configurations, accommodating up to 4, 8, or 16 modules. 

All _groov_ power supplies, voltage converters, adapters, and processors, are UL/cUL listed and compliant with the ATEX, Low Voltage, and EMC CE directives. Each module is factory tested twice before shipment and most modules are guaranteed for life.

## ASSEMBLING AND MOUNTING ON A DIN RAIL 

The chassis is built with DIN rail adapters for use on 35 mm DIN rail. No additional assembly is required. 

Mount the chassis empty. Install the _groov_ EPIC products, like the power supply, the processor, and the modules, after you have mounted the chassis onto the DIN rail. 

To mount the chassis on to a DIN rail, do the following tasks: 

**1.** Hold the chassis so that the module connector numbers are facing right side up. 

**2.** Hold the chassis at an angle such that the top of the DIN rail adapter is away from the DIN rail and the bottom of the DIN rail adapter can slide behind the bottom lip of the DIN rail. 

**3.** Push the bottom part of the chassis upward, making sure that you feel the clip catch on to the rail, and simultaneously push the top half of the chassis toward the DIN rail until the top of the DIN rail adapter engages the top lip of the DIN rail. 

Before you release the chassis, verify that the top and bottom of the DIN rail adapters have engaged the DIN rail. 

**4.** Mount the power supply, the processor, and the modules onto the chassis. 

## ASSEMBLING AND MOUNTING CHASSIS ON A PANEL 

## Using Chassis as Template 

Use this method if you have the chassis on-hand to use as a template. 

**1.** Review the mounting hole dimensions on the next page and the dimensional drawings in previous pages to determine required product and option clearances. 

   **3.** Use the chassis as a template to mark holes. 

   **4.** After the chassis is securely mounted, attach the backplane with the retention screws provided. 

**2.** Opto 22 ships the backplane attached to the chassis, so remove the backplane to gain access to the chassis mounting holes. 

## Alternate Method: Prefabrication of Panels 

If you do not have the chassis on-hand, review the diagrams on the next page to determine mounting hole positions.

Visualization, data handling, and connectivity in a compact, industrial box: that’s the _groov_ Edge Appliance. Included are: 

- _groov_ View for building and viewing operator interfaces on PCs and mobile 

- Node-RED for building simple logic flows 

- Ignition Edge® from Inductive Automation®, for OPC-UA drivers and MQTT/Sparkplug IIoT communications 

## Older products 

From solid state relays (our first products) to world-famous G4 and SNAP I/O, to SNAP PAC controllers, Opto 22 products last a long time. You can count on us to give you the reliability and service you expect. 

## QUALITY 

Founded in 1974, Opto 22 has established a worldwide reputation for high-quality products. All are made in the U.S.A. at our manufacturing facility in Temecula, California.
