4 Position of Connectors and Functions of VPNRouter iR 5221 and VPNRouter iR 3220
The group of four in the middle is for the DIN Rail mounting clamp. This may be mounted in
standard orientation, or turned by 90° to provide for a (seldom used) horizontal xture on the DIN
Rail.
Figure
is a reference for the positions of front side connectors. It is for demonstration only.

shows the positions of screws for xing. Note, this is upside down with respect to the
front side. The two M3 screw positions in the middle allow to x an DIN Rail clamp. There is also
the position of a possible antenna socket near the Reset button.
4. Position of Connectors and Functions of VPNRouter iR 5221 and
VPNRouter iR 3220
First the connectors and functions located on the top side of VPNRouter iR 5221 and VPN-
Router iR 3220 are described. The next components are those on the front side, nally followed by
those on the bottom side.
4.1. Power
The VPNRouter device is powered by a single power supply in a wide range from 12 V to 50 V
DC. A suitable power supply adapter is available as add-on component, and part of the starter kit
package. Connect the cable to the power jack at the top side of VPNRouter, and plug the adapter
into the socket. The Power LED (red) on VPNRouter will light. You can connect a power supply
of your choice, providing the technical requirements are met.
Warning:
disconnect the VPNRouter from power supply before performing installation or wiring.
The wire size must follow the maximum current specications. The maximum possible current in
the power wires as well as in the common wires must be taken under consideration. If the current
rises above the maximum ratings, the wiring can overheat, causing serious damage to your equip-
ment. When powered, the VPNRouter's internal components generate heat, and consequently
the outer case may feel warm to the touch.
4.1.1. Connection and Polarity
Power is connected via three clamps on a terminal block, located on the top side of VPNRouter iR 5221/VPNRouter iR 3220.
Warning:
do not confuse the CAN connector at the bottom side for power input. Such may
damage the CAN bus port.
