Check whether the DIN-Rail mounting kit thatStep 1 comes with the device is installed firmly.
Insert the bottom of DIN-Rail mounting kit (one sideStep 2 with spring support) into DIN-Rail, and then insert
the top into DIN-Rail.
Tips:
Insert a little to the bottom, lift upward and then insert
to the top.
Check and confirm the product is firmly installed onStep 3 DIN-Rail, and then mounting ends.
【Disassembling DIN-Rail】
Power off the device.Step 1 After lift the device upward slightly, first shift out theStep 2 top of DIN-Rail mounting kit, and then shift out the
bottom of DIN-Rail, disassembling ends.
Attention before powering on:
Power ON operation: first connect power line to the
connection terminal of device power supply, and then
power on.
Power OFF operation: first unpin the power plug, and
then remove the power line, please note the operation
order above.
【Power Supply Connection】
DC power supply
This series provide redundant power input function and 2
input terminal blocks of PWR1 and PWR2, which can be used
separately or connected to 2 independent
DC power supply systems. The device
can be simultaneously connected to two
power supply systems via two terminal
blocks, and it can run normally without
interruption when one of the power supply systems fails,
improving the reliability of network operation.
Power supply range: 24VDC (12~48VDC).
【Relay Connection】
The access terminal blocks of relay locate on
the top panel of the device. The terminal blocks
are a pair of normally open contacts in the alarm
relay of the device. They are closed circuit in the status of
normal no alarm, and open circuit when any warning message
occurs. IES318 series support 1 relay warning message
output (this series only support power down alarm of the port
link and warning message output of customizable power
supply). It can be connected to alarm indicator, alarm buzzer,
or other switching value collecting devices for timely warning
operating staffs when the warning message occurs.
【DIP Switch Settings】
This series provide 10 pins DIP switch for
function settings, where "ON" is the enable valid
terminal.
DIP switch definitions as follows:
Enabled alarm settings
switch of the corresponding
port
Set the switch to
ON for enabling the
alarm
The alarm settings of the
second power supply
ON represents the
status of alarm
The alarm settings of the
first power supply
ON represents the
status of alarm
【Checking LED Indicator】
