Power 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 protection,
Reverse connection protection. Voltage input range is 12
～
48VDC

.
AC Series Switch:
The Industrial Ethernet switches have singe power and redundancy power two kinds of power input. The
singe power AC series top panel provides 3 bit terminal block for 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 takes care of
operation sequence.
2.3 Relay connection
Relay access terminals in the top panel of the device. Between the 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.)
