【Power supply input】
DC Series Switch:
The switch top panel provided 4 bit power supply input terminal
block, support DC input. DC power supply input supported
redundancy function, provided PWR1 and PWR2 power input,
can use for single, and can connect 2 separately power supply
system, use 1 pair terminal block connect the device at the same
time. If one of the power systems broke, the device can work
un-interruptible.
Built-in
overcorrect
connection protection. Voltage input range is 12 ～ 48VDC
（terminal block defined as: V1-、V1+、V2-、V2+）.
AC Series Switch:
The Industrial Ethernet switches have singe power and
redundancy power two kinds of power input. The singe power AC
series

bit
100~240VAC/DC power entered (L/+, PG, N/-)
Important notice:
1. Power ON operation: first of all, insert power cable's terminal
block into device's power port, then insert power supply plug into
power source
2. Power OFF operation: First off all, unpin power plug, then
strike the terminal block, please take care of operation sequence.

recovery default factory. 3 is for upgrade. Please power off and
power on when you change the status of DIP switch.
【Relay connection】
Relay access terminals in the top panel of the device. Between the

for
two terminal relay, as an open circuit state in normal non alarm
state, when there is any alarm information to the closed state. The
two terminal block connector are used to detect both power failure
and port failure. The two wires attached to the Fault contacts form
an open circuit when the device has lost power supply from one of
the DC power inputs or one of the ports is failure. (Note: The AC
power switch does not support power alarm.)
