Note: “+” and “-” signs represent the polarity of the wires that make up each wire pair.
2.7 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the RJ45 port connections. The cable between the switch
and the link partner (switch, hub, workstation, etc.) must be less than 100 meters (328 ft.) in length.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications for both
telecommunication and data communication applications.
Caution: Please employ optional optical transceiver (SFP/Fixed Fiber) that complies with IEC-60825-1 and
classified as Class 1 laser product.
Attention: Veuillez utiliser un émetteur-récepteur optique en option (SFP/fibre fixe) conforme à la norme
IEC-60825-1 et classé comme produit laser de classe 1.

2.8 Wiring the Power Inputs
Caution: Please follow the steps below when inserting the power wire.
Attention: Veuillez suivre les étapes ci-dessous lors de l'insertion du câble d'alimentation.
1. Insert the positive and negative wires into the PWR1 (V1+, V1-) and PWR2 (V2+, V2-) contacts on the terminal block
connector as shown below in Figure 2.6.
Figure 2.6 - Power Terminal Block
2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in Figure 2.7.
Figure 2.7 - Power Terminal Block
Caution:
Only use copper conductors, 125°C, tighten to 5 lbs.
The wire gauge for the terminal block should range between 18~20 AWG.
Attention:
Utilisez uniquement des conducteurs en cuivre, 125°C, serrez à 5 lb.
Le calibre des fils du bornier doit être compris entre 18 et 20 AWG.

LMP-2012G-SFP Series - Hardware Manual - v1.0
2.9 Wiring the Relay Contact
The fault alarm contact is in the middle of the terminal block connector as the picture shows below in Figure 2.8. By
inserting the wires, it will detect the fault status including power failure or port link failure (managed industrial switch
only), and form a normal open circuit. An example is shown below in Figure 2.8.
Figure 2.8 - Wiring the Fault Alarm Contact
Caution:
The wire gauge for the terminal block should range between 12 ~ 24 AWG.
If only using one power source, jumper Pin 1 to Pin 5 and Pin 2 to Pin 6 to eliminate power fault alarm.
Attention:
Le calibre des fils du bornier doit être compris entre 12 et 24 AWG.
Si vous n'utilisez qu'une seule source d'alimentation, connectez les broches 1 à 5 et les broches 2 à 6 pour
éliminer l'alarme de panne de courant.
2.10 Grounding Note
Grounding and wire routing help limit the effects of noise due to Electromagnetic Interference (EMI). Run the ground
connection from the ground screw to the grounding surface prior to connecting devices. The grounding screw symbol is
shown below in Figure 2.9.
