Installation - Maple Systems

The location chosen for installing the Switch may greatly affect its performance. When
selecting a site, we recommend considering the following rules:

Install the Switch in an appropriate place. See Technical Specifications for the acceptable temperature and humidity ranges.
Install the Switch in a location that is not affected by strong electromagnetic field generators (such as motors), vibration, dust, and direct sunlight.
Leave at least 10cm of space at the front and rear of the unit for ventilation.

Hardware Installation

✓ Step 1: Unpack the device and other contents of the package.
✓ Step 2: Fasten DIN-Rail kit on the rear of the switch.
✓ Step 3: Connect the 20~57V DC power supply to the PWR & RPS terminal block
on the top of the Switch (Refer to “Wiring Redundant Power Inputs”)
✓ Step 4: Connect the Ethernet (RJ45) port to the networking device and check the
LED status to ensure the connection is established.

DIN Rail Installation

The LITE-MANAGED SWITCH has a DIN rail bracket on the back of the Switch to
satisfy the mounting installation.
Location: The LITE-MANAGED SWITCH can be DIN-Rail-mounted in cabinet or
enclosure.

Mounting the switch:

Place the LITE-MANAGED SWITCH on the DIN rail from above using the slot and push
the front of the switch toward the mounting surface until it snaps into place with a click
sound.

Dismounting the Switch

Push the switch down to free the bottom of the plate from the DIN rail.
Rotate the bottom of the device towards you and away from the DIN rail.
Once the bottom is clear of the DIN rail, lift the device straight up to unhook it from
the DIN rail.

Ground the Switch

Before powering on the switch, ground the switch to earth.
Ensure the rack on which the switch is to be mounted is properly grounded and
incompliance with ETSI ETS 300 253. Verify that there is a good electrical connection to
the grounding point on the rack (no paint or isolating surface treatment).

Wiring Power Inputs

You can use “Terminal Block (PWR)” for primary power and “Terminal Block (RPS)” for
secondary power source, to be a Redundant Power Input.

Redundant Power Input

Choose “Terminal Block (PWR)” as primary power. If you choose “Terminal Block (PWR)”, please refer below.

✓ Method: Insert the terminal block connector which includes “PWR” and “RPS” into
the terminal block receptor.

Connect power cables to terminal block: Use your finger to press the orange plug on top
of terminal block connector to insert power cables

Please read and follow these guidelines:

Use separate paths to route wiring for power and devices. If power wiring and
device wiring paths must cross, make sure the wires are perpendicular at the
intersection point.
NOTE: Do not run signal or communications wiring and power wiring through the
same wire conduit. To avoid interference, wires with different signal characteristics
should be routed separately.
You can use the type of signal transmitted through a wire to determine which wires
should be kept separate. The rule of thumb is that wiring that shares similar
electrical characteristics can be bundled together
You should separate input wiring from output wiring
We advise that you label the wiring to all devices in the system.

Wiring the Alarm Contact

The Alarm Contact consists of the two middle contacts of the terminal block on switch’s
top panel.
ALM: The two middle contacts of the 6-contact terminal block connector are used to detect
both power faults and port faults. The two wires attached to the ALM contacts form an
open circuit when:

The Switch has lost power from one of the DC power inputs.
OR
One of the ports for which the corresponding PORT ALARM DIP Switch is set to ON
is not properly connected.
If neither of these two conditions is satisfied, the ALM circuit will be closed.

Power on the Unit

The Switch accepts the power input voltage from 20~57V DC.
✓ Wiring appropriate power source as above guideline before turning on the power.
✓ Check the front-panel LEDs as the device is powered on to verify that the Power
LED is lit. If not, check that the power cable is correctly and securely plugged
in.
Notice: Turn off the power before connecting modules or wires.

The correct power supply voltage is listed on the product label. Check the voltage
of your power source to make sure that you are using the correct voltage. Do NOT
use a voltage greater than what is specified on the product label.
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 current levels go above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

Manual Reboot / Reset Switch

Switch contains “Reset” button through which you can manually reboot or reload to factory
default settings.
✓ Press the “Reset” button for more than 2 seconds to reboot the switch.
✓ Press the “Reset” button for more than 5 seconds to reload the factory default settings
to the switch.

Attention	This product is intended to be mounted to a well-grounded mounting surface such as a metal panel.
Caution	The earth connection must not be removed unless all power supply connection has been disconnected. Caution: The device is installed in a restricted-access location it has a separate protective earthing terminal on the chassis that must be permanently connected to earth ground to adequately ground the chassis and protect the operator from electrical hazards.
Attention	The product should be mounted in an Industrial Control Panel and the ambient temperature should not exceed 60°C.
Attention	A corrosion-free mounting rail is advisable. When installing, make sure to allow for enough space to properly install the cabling.
