JetNet 3705-24V 5-port Industrial Fast Ethernet Power over Ethernet Switch Wiring the Power Inputs Please follow the steps below to wire the power cord which from the other compliant external DC power supplier. Insert the positive and negative wires into the PWR1 (V1+, V1-) and PWR2 (V2+, V1-) contacts on the terminal block connector as shown in Figure-6.
Wiring the Fault Alarm Contact The fault alarm contact is in the middle of terminal block connector as the picture shows below. Inserting the wires, will detect the fault status including power failure or port link failure (managed industrial switch only) and from a Normally Close circuit. Please refer to Figure-8 for the fault alarm contact, and Figure-9 shows the application example for the fault alarm operation.
JetNet 3705-24V 5-port Industrial Fast Ethernet Power over Ethernet Switch Mounting Installation DIN-Rail Mounting The DIN-Rail bracket is screwed on the switch on the production line in the factory. If the bracket is not screwed on the switch, please refer to Figure-10 to screw it on the switch.
After the DIN-Rail bracket is screwed on the rear side of the switch, insert the top of the bracket into the rail. Then, lightly pull-down the bracket into the rail. Be sure the DIN rail specification is compliance EN 50022 standard. (3.5cm DIN rail ) Figure-11 Check if the bracket is tightened on the rail or not.
