Connecting the Hardware
This section describes how to install SIM cards in the WDR-3124A, mount the WDR-3124A on a DIN-rail or a
wall, and connect the WDR-3124A to a computer for the first time.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your device. The WDR-3124A should be
secured at one location.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings,
the wiring could overheat, causing serious damage to your equipment.
Temperature Caution!
Be careful when handling the device. When plugged in, the device internal components generate heat, and
consequently the casing may feel hot to the touch.
You should also take note of the following guidelines:
•
Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure that the wires are perpendicular at the intersection point.
Note:
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
•
Use the type of signal transmitted through a wire to determine which wires should be kept separate. The
rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
•
Keep input wiring and output wiring separate.
•
Where necessary, it is advisable to label the wiring to all devices in the system.
