2. Push the SFP module down.

Remove SFP Module

1. Press and remove the SFP cable.

2. Open the SFP module and remove it.

WIRING POWER INPUTS

1. Insert the positive and negative wires into the PWR1 (+,-) and PWR2

(+,-) on the 4-contact terminal block connector.

2. Tighten the screws to prevent the wires from loosening.

QP-748MI User Manual

WIRING FAULT ALARM

1. Insert the wires into the left two contacts of the 4-contact terminal

block (Fault Alarm Relay).

2. Tighten the screws to prevent the wires from loosening.

3. The relay will detect the power and link failure.

4. Users can connect the relay to an alarm and buzzer so that when

the relay forms an open circuit, the users will be notified.

WIRING DIGITAL INPUTS

1. Insert the positive and negative wires into the right two contacts

(+,-) of the 4-contact terminal block (DI).

2. Tighten the screws to prevent the wires from loosening.

3. The system will detect the voltage go through the DI.

▪+13 to +30V for state "1"

▪-30 to +3V for state "0"

▪Max. input current: 8mA

DOUBLE-SECURE POWER INPUT FAULT ALARM

The power inputs are designed as a "common

negative", which implies that the negative input is

connected, but "double-secure" is supported to

prevent the unnotified failure of power from one of the

negative inputs. If one of the negative power input

fails, the system will detect it and the system will

trigger the event if the users set the fault alarm or

event log for powers.

MOUNTING

Din-Rail Mounting

a. Screw the DIN-Rail bracket to the switch.

b. Insert the top of the DIN-Rail bracket to the DIN-

Rail track.

c. Pull down the DIN-Rail bracket to the DIN-Rail track and check if it is mounted tightly on the DIN-Rail

track.
