MOUNTING INSTRUCTIONS

This operator interface is designed for through-panel mounting. A panel cut-

out diagram and a template are provided. Care should be taken to remove any

loose material from the mounting cut-out to prevent that material from falling

into the operator interface during installation. A gasket is provided to enable

sealing to NEMA 4X/IP66 specification. Install the ten kep nuts provided and

tighten evenly for uniform gasket compression.

Note: Tightening the kep nuts beyond a maximum of 17 inch-pounds (1.92 N-

m) may cause damage to the front panel.

CONNECTING TO EARTH GROUND

Each G308 has a chassis ground terminal on the back of the unit. Your unit

should be connected to earth ground (protective earth).

The chassis ground is not connected to signal common of the unit.

Maintaining isolation between earth ground and signal common is not required

to operate your unit. But, other equipment connected to this unit may require

isolation between signal common and earth ground. To maintain isolation

between signal common and earth ground care must be taken when connections

are made to the unit. For example, a power supply with isolation between its

signal common and earth ground must be used. Also, plugging in a USB cable

1. USB’s shield may be connected to earth ground at the host. USB’s shield

in turn may also be connected to signal common.

POWER SUPPLY REQUIREMENTS

The G308 requires a 24 VDC power supply rated at 24 W. Your unit may

draw considerably less than 24 W depending upon the options being used. As

additional features are used your unit will draw increasing amounts of power.

Items that could cause increases in current are additional communications,

optional communications card, CompactFlash card, and other features

programmed through Crimson.

In any case, it is very important that the power supply is mounted correctly if

the unit is to operate reliably. Please take care to observe the following points:

– The power supply must be mounted close to the unit, with usually not

more than 6 feet (1.8 m) of cable between the supply and the operator

interface. Ideally, the shortest length possible should be used.

– The wire used to connect the operator interface’s power supply should

be at least 22-gage wire. If a longer cable run is used, a heavier gage

wire should be used. The routing of the cable should be kept away from

large contactors, inverters, and other devices which may generate

significant electrical noise.

– A power supply with a Class 2 or SELV rating is to be used. A Class 2

or SELV power supply provides isolation to accessible circuits from

hazardous voltage levels generated by a mains power supply due to

single faults. SELV is an acronym for “safety extra-low voltage.” Safety

extra-low voltage circuits shall exhibit voltages safe to touch both under

normal operating conditions and after a single fault, such as a

breakdown of a layer of basic insulation or after the failure of a single

component has occurred.

CONFIGURING A G308

The G308 is configured using Crimson software. Crimson is available as a free

download from Red Lion’s website, or it can be purchased on CD. Updates to

Crimson for new features and drivers are posted on the website as they become

available. By configuring the G308 using the latest version of Crimson, you are

assured that your unit has the most up to date feature set. Crimson software can

configure the G308 through the RS232 PGM port, USB port, or CompactFlash.

The USB port is connected using a standard USB cable with a Type B connector.

The driver needed to use the USB port will be installed with Crimson.

The RS232 PGM port uses a programming cable made by Red Lion to

connect to the DB9 COM port of your computer. If you choose to make your

own cable, use the “G308 Port Pin Out Diagram” for wiring information.

The CompactFlash can be used to program a G3 by placing a configuration

file and firmware on the CompactFlash card. The card is then inserted into the

target G3 and powered. Refer to the Crimson literature for more information on

the proper names and locations of the files.

CABLES AND DRIVERS

Red Lion has a wide range of cables and drivers for use with many different

communication types. A list of these drivers and cables along with pin outs is

available from Red Lion’s website. New cables and drivers are added on a

regular basis. If making your own cable, refer to the “G308 Port Pin Outs” for

wiring information.

USB, DATA TRANSFERS FROM THE

COMPACTFLASH CARD

In order to transfer data from the CompactFlash card via the USB port, a

driver must be installed on your computer. This driver is installed with Crimson

and is located in the folder C:\Program Files\Red Lion Controls\Crimson

2.0\Device\ after Crimson is installed. This may have already been

accomplished if your G308 was configured using the USB port.

Once the driver is installed, connect the G308 to your PC with a USB cable, and

follow “Mounting the CompactFlash” instructions in the Crimson 2 user manual.

All tolerances ±0.010" (±0.25 mm).

ALL NONINCENDIVE CIRCUITS MUST BE WIRED USING

DIVISION 2 WIRING METHODS AS SPECIFIED IN ARTICLE 501-

4 (b), 502-4 (b), AND 503-3 (b) OF THE NATIONAL ELECTRICAL

CODE, NFPA 70 FOR INSTALLATION WITHIN THE UNITED

STATES, OR AS SPECIFIED IN SECTION 19-152 OF CANADIAN

ELECTRICAL CODE FOR INSTALLATION IN CANADA.

WARNING - DO NOT CONNECT OR DISCONNECT CABLES

WHILE POWER IS APPLIED UNLESS AREA IS KNOWN TO BE

NON-HAZARDOUS. USB PORT IS FOR SYSTEM SET-UP AND

DIAGNOSTICS AND IS NOT INTENDED FOR PERMANENT

CONNECTION.

The protective conductor terminal is bonded to conductive

parts of the equipment for safety purposes and must be

connected to an external protective earthing system.
