Real Time Clock (RTC)
The RKP-A110’s real-time clock is powered by a lithium battery. You can easily replace the battery yourself
using an optional battery kit. Refer Replacing the RTC Batteryy section for details. However, please note
that there is a risk of explosion if the battery is replaced by an incorrect type of battery. Contact a qualified
Moxa support engineer if you have any questions about the RTC battery.
ATTENTION
There is a risk of explosion if the battery is replaced by a battery of the incorrect type.

3. Hardware Connections
The RKP-A110 Series computers are compact and rugged, making them suitable for industrial applications.
The LED indicators allow users to monitor performance and quickly identify trouble spots. Multiple ports are
provided for connecting a variety of different devices. The RKP-A110 Series computers come with a reliable
and stable hardware platform that lets you devote the bulk of your time to application development. This
chapter describes the hardware installation and connector interfaces of the RKP-A110 computers.
Installing Rack-mounting Ears
The RKP-A110 computer comes preinstalled with two rack-mounting ears. If they are not, use the rack-
mounting kit to install the ears. The rack-mounting kit includes 2 rack-mounting ears and 8 screws (size:
M4x6), four for each mounting ear.
After installing the rack-mounting kit, do the following to install the computer on a rack.
Step 1.
If the mounting ears are not installed, use four screws each to attach
the mounting ears on both sides of the computer.
Step 2:
Place the
computer on a rack and use another four screws to secure
the rack
-mount ears to the rack.

The second set of four screws needs to be
purchased separately. Refer to the figure on
the right for the specifications.
Connecting the Power
The RKP-A110 computers are provided with 2-pin power input connectors in a terminal block on the front
panel. Insert the power-cord wires into the connectors and tighten them to secure the wires in place. Plug in
the power cable to a power source. The power LED will light up to indicate that power is being supplied to
the computer. It should take about 30 to 60 seconds for the operating system to complete the boot-up
process.

The power input specification is given below:
The DC power source rating is 12 VDC @ 5.4 A, or 24 VDC @ 2.6 A. An 18 AWG cable size DC power is
suggested.
ATTENTION
This product is intended to be supplied by a Listed Power Supply with output marked LPS and rated to
deliver 12 VDC at a maximum of 5.4 A, or 24 VDC at a maximum of 2.6 A, and minimum Tma=60˚C. If
you need assistance with purchasing a power adapter, contact the Moxa technical support team.
ATTENTION
Before connecting the RKP-A110 computer to the DC power inputs, ensure that the DC power source
voltage is stable.
•The wiring for the input terminal block shall be installed by qualified and experienced professionals.
- Wire Type: Cu, FW2
- Use 18-12 AWG wire size and a torque value of 0.5 N-m.
•Use only one conductor in a clamping point between the DC power source and the power input.

RKP-A110 Series Hardware User's Manual

NOTE
If using Class I adapter, the power cord adapter should be connected to a socket outlet with an earthing
connection or the power cord and adapter must comply with Class II construction.
NOTE
For surge protection, connect the grounding connector located below the power connector with the earth
(ground) or a metal surface.
An 18 AWG cable size conductor must be used when the connection to the external grounding screw is
utilized. The heat sink is grounded to the chassis by an internal screw.
WARNING
為避免電磁干擾，本產品不應安裝或使用於住宅環境。
Wiring Requirements
The following common safety precautions should be observed before installing any electronic device:
•Power wires and communication/signal wires should be routed through separate paths. If power and
communication/signal wires must cross paths, make sure the wires are perpendicular at the intersection
point.
NOTE
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
•Use the type of signal transmitted through a wire to determine which wires should be bundled together
and which ones should be kept separate. The rule of thumb is that wiring that carries similar electrical
signals can be bundled together.
•When necessary, we strongly advise labeling the wiring for all devices in the system.
ATTENTION
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your device.
Electrical Current Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current goes above the maximum rating, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Be careful when handling the unit. When the unit is plugged in, the internal components generate heat,
and consequently the outer casing may feel hot to the touch.

Restricted Access Location
This equipment is intended to be used in Restricted Access Locations, such as a computer room, with
access limited to SERVICE PERSONAL or USERS who have been instructed on how to handle the metal
chassis of equipment that is so hot that special protection may be needed before touching it. The location
should only be accessible with a key or through a security identity system.
Ethernet Ports
The RKP-A110 has 4 or 12 Ethernet ports. When a LAN cable is properly connected, the LEDs on the front
panel will glow to indicate the connection status.
