Power supply input
】
The IT-ES1024-IU series Ethernet switch have singe power
and redundancy power two kinds of power input. The singe
power series rear panel provides 5 bit wiring terminal for
AC100~240V power entered (L/+, GND, N/-) and relay
output (R+, R-).The unmanaged Ethernet switch relay alarm
function is invalid. Terminal diagram is as follows:
The redundancy power series rear panel provides two
terminal blocks (5 bits) for P1 and P2 input. The redundant
power can be used independently. P1 and P2 can supply
power at the same time, once either of these two powers fails,
another power can acts as backup automatically to ensure
reliability of the network. Voltage input range is 100
～
240VAC (terminal block defined as P1: L/+, GND, N/ -; P2:
L/+, GND, 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.
