WARNING

When end

users are using Optical SFP Communications

m odules, these must be lim ited to Laser Class 1.

WARNING

Use of the controls or adjustments or the performance of

procedures other than those specified herein may result in

hazardous radiation exposure.

Grounding the Moxa Industrial Rackmount Switch

Grounding and wire routing help lim it the e ffects of noise due to

electromagnetic interference (EMI). Run the ground connection from

the ground screw to the grounding surface prior to connecting devices.

NOTE

Using a shie lded cable achieves better electromagnetic

compatibility.

Connecting the Power Inputs

The RKS-G4028 Series switches support various types of power supply.

•LV m odels provide one 24/48 VDC power input

•2LV m odels provide two 24/28 VDC power inputs

•HV m odels provide one 110/220 VDC/VAC power input

•2HV models provide two 110/220 VDC/VAC power inputs

•PoE models provide 1 EPS (e xte rnal power supplies) with 48 VDC

power inputs

Wiring Requirements

WARNING

Do not disconnect modules or wires unless power has been

switched off or the area is known to be non

-hazardous. The

de vice m ay only be connected to the supply voltage shown on

the type plate. The device is designed for ope

ration with a

Safety Extra

-Low Voltage (SELV) or an isolated power supply,

which means that they may only be connected to the supply

voltage connections and to the signal contact with a SELV or an

isolated power supply in compliance with

IEC 62368-1/E N

62368-1/UL 62368-1 or UL 61010.

Power Terminal Blocks

The connection for EPS (external power supply) / PWR1 (po we r s upply

1) and PWR2 (po wer supply 2) are located on the fro nt panel as shown

be low.

LV Models Power Terminal Blocks

1. Inse rt the negative/positive (-/+) DC wires into the te rminals.

2. Inse rt the terminal block connector prongs into the terminal block

receptor.

NOTE

In orde r to have higher levels of protection against surge, it is

suggested to install a surge protector in front of the power

input of the PoE powered device so that it is suitable for use in

IEC 61850 conditio ns.

NOTE

When wiring the power input, we suggest using the cable type -

AWG (Am erican Wire Gauge) 16

-20 (1.31-0.519 mm2

) and the

corresponding pin type cable te rminals. The rate d temperature

of wiring should be at least 105°C.

NOTE

When wiring the PoE power input, we suggest using the cable

type

- AWG (American Wire Gauge) 16 (1.31 mm2) and the

corresponding pin type cable te rminals. The rate d temperature

of wiring should be at least 105°C.

NOTE

When wiring the grounding connector screw, we

suggest using

the cable type

- AWG (American Wire Gauge) 16 (1.31 mm2)

and the corresponding pin type cable terminals. The rated

tem perature of wiring should be at least 105°C.

NOTE

Whe n HV m o dels are c onnected with an AC power source,

please make sure the Ground wire is well connected.

NOTE

When your purchase a device with two power modules, both

power units will be activated simultaneously, which will enable

powe r re dundancy.

NOTE

The reverse power input connection will not activate the device

or PoE input.

Wiring the Relay Contact

Each power module has one relay output that can be used to detect

user-c onfig ured e vents. Two wires are attached to the relay pins with

‘No rm ally Closed’ and ‘Normally Open’ options.

1. Inse rt the wires into the terminals.

2. Inse rt the terminal block connector prongs into the terminal block

receptor.

- 7 -

FAULT:

The relay contact of the 2-pin terminal block connector is used to detect

user-configured events. The two wires attached to the fault contacts

form an open circuit when a user-configured event is triggered. If a

user-configured event does not occur, the fault circuit remains closed.

USB Connection

Use Moxa’s USB Automatic Backup Configurator ABC-02-

USB to connect to the USB host port to backup and restore

configuration files, auto

-load configuration file s, upgrade

firm ware, and backup system log files.

Type A

Console Port Connection

The RKS device has one RJ45 console port (RS-232), located on the

front panel. Use an RJ45-based cable to connect the RKS’s console port

to your PC’s COM port. You may then use a console terminal program,

such as Moxa PComm Terminal Emulator, to access the RKS device t h at

has a baud rate of 115200. Refer to the following table figure for the

pin definition.

The Reset Button

Depress the Reset button for five continuous seconds to load the

factory default settings. Use a pointed object, such as a straightened

paper clip or toothpick, to depress the Reset button. When you do so,

the STATE LED will start to blink about once per second. Continue to

depress the STATE LED until it begins blinking m ore rapidly; this

indicate s that the button has been depressed for five seconds and you

can re le ase the Reset button to load factory default settings.

NOTE

Do NOT powe r off the switch when loading default settings

Placing the Round Stickers on Module Screws

Moxa offe rs e ig ht round s tickers in the s hipment package. These

stickers are to be placed on the screws of the modules to avoid

unauthorized persons accessing the modules. If the stickers are broken,

users will know the modules have been accessed by unauthorized

pe rsons. The figure below highlights the locations of the screws.

- 8 -

Follow these steps to place the stickers.

1. Use a cloth to clean the surface of the screws with 75% alcohol

solution.

2. We suggest you use a tweezer to place the stickers.

3. Press the stickers d o wn with 15PSI (po und per square inc h) for at

least 15 seconds.

4. Keep the device at room temperature for 24 hours before

de ploying the devices in hars h environments.

NOTE

1. Place the stickers carefully as they are thin and fragile.

The ideal environment for the stickers to be stored in is

22°C (72°F) and 50% relative humidity.

Keep the extra two stickers in a safe place so that no

unauthorized persons can access them.
