Note
Connections 1-2 and 3-4 are redundant. We recommend keeping this redundancy to guarantee device
availability.
3.3.1.2 Power cable
The power cable is not supplied with the router. The estimated maximum consumption for this equipment is 150 mA
operating at 110 VDC, or 830mA operating at 24 VDC. Any cable with a cable gauge greater than or equal to 0.2
mm (AWG24) is acceptable. The type of cable and its gauge, however, will be determined by the characteristics of
2
the female connector used.
For example, for a female Phoenix Contact SACC-M12FS-4CON-PG7-M or equivalent, we recommend using a
cable with an outside diameter of 4-6 mm with four AWG24-AWG18 conductors.
You don't need a shielded cable. However, if you intend to use one, we recommend attaching the cable to the
grounding point on the other side of the router, to the ground point on the power supply or to both.
