NE-4100 Series User’s Manual

Getting Started

Wiring Requirements

This section describes some important safety precautions that you should pay attention to before proceeding with any installation.

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your evaluation boards for the NE-4100 Series modules.

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!

Please take care when handling the evaluation boards. When plugged in, the evaluation boards’ internal components generate heat, and consequently the board may feel hot to the touch.

You should also pay attention to the following points:

#Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure 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.

#You can 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 strongly advised that you label wiring to all devices in the system.

Attaching NE-4100T to the Evaluation Board

Before connecting your NE-4100-ST to the power supply, network, and serial device, you first need to attach NE-4100T to the NE-4100-ST evaluation board. In the center of the evaluation boards, there is a square with one white inverted triangle (shown as black in the figure) on one of its sides, and 2 rows of female sockets on the other two sides. The NE-4100T board also has a white inverted triangle on one of its sides. When attaching your NE-4100T to NE-4100-ST, make sure these 2 white inverted triangles are facing the same direction, as shown in the following figure.
