Grounding the Moxa Industrial Rackmount Switch
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting devices.
Connecting the Power Inputs
The IKS-6726/6728 series of switches supports both 110/220 VAC and
24/48 VDC power supplies.
- 4 -
AC Power Inlets
The connection for PWR1 (power supply 1) and PWR2 (power supply 2)
are located on the rear side (shown below). Be sure to use a standard
power cord with an IEC C13 connector, which is compatible with the AC
power inlet.
DC Power Terminal Blocks
The connection for PWR1 (power supply 1) and PWR2 (power supply 2)
are located on the rear side (shown below).
STEP 1: Insert the negative/positive DC wires into the V-/V+ terminals,
respectively.
STEP 2: To keep the DC wires from pulling loose, use a small flat-blade
screwdriver to tighten the wire-clamp screws on the front of the terminal
block connector.
STEP 3: Insert the plastic terminal block connector prongs into the
terminal block receptor.
Wiring the Relay Contact
Each IKS-6726/6728 switch has one relay output.
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.
RS-232 Connection
The Moxa IKS-6726/6728 has one RS-232 (10-pin RJ45) console port,
located on the front panel. Use either an RJ45-to-DB9 or RJ45-to-DB25
cable to connect Moxa IKS-6726/6728 console port to your PC’s COM port.
You may then use a console terminal program, such as Moxa PComm
Terminal Emulator, to access Moxa IKS-6726/6728’s console
configuration utility.

The Reset Button
Depress the Reset button for 5 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. This will cause the STATE LED
to blink on and off. The factory default settings are loaded once the
STATE LED stops blinking (after about 5 seconds). At this point, you can
release the Reset button.
LED Indicators
The front panel of the IKS switch contains several LED indicators. The
function of each LED is described in the table below.

Rack Mounting Instructions
1. Elevated Operating Ambient: If installed in a closed or multi-unit
rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
2. Reduced Air Flow: Installation of the equipment in a rack should
be such that the amount of air flow required for safe operation of the
equipment is not compromised.
3. Mechanical Loading: Mounting of the equipment in the rack
should be such that a hazardous condition is not achieved due to
uneven mechanical loading.
4. Circuit Overloading: Consideration should be given to the
connection of the equipment to the supply circuit and the effect that
overloading of the circuits might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
5. Reliable Grounding: Reliable grounding of rack-mounted
equipment should be maintained. Particular attention should be
given to supply connections other than direct connections to the
branch circuit (e.g. use of power strips)."
