Notes on CAT5e/6 cables (for Ethernet LAN connection)
•
Do not bend the cables to an extent where the radius is less than 25
mm (1”). Communication failure could result.
•
Do not remove the CAT5e/6 cable jacket more than necessary.
Do not route a CAT5e/6 cable outdoors from a multi-building control unit directly. When routing a CAT5e/6 cable
outdoors from a switching hub, etc., use a model that supports outdoor wiring.

•
Arrange the color code of the RJ45 connections in accordance with
EIA/TIA-568A or 568B.
•
Be sure to check the condition of cable connections with a LAN
checker before connecting with a LAN cable.
•
An RJ45 connector with a cover cannot be connected to the port for
CAT5e/6. Use a cable without a cover.
•
Do not pull or put excess strain on CAT5e/6 cables.
•
Use a straight-through cable for connecting units.

• Use PE (polyethylene)-insulated PVC jacket cable.
Parallel or jacketed 2-conductor, mid-capacitance non-shielded cable is
recommended.
• Never use individual conductors, twisted pair cable or coaxial cable.

To connect low voltage wires, either crimp them with a crimp sleeve or solder them, and then insulate by covering
with insulating tape.

1. Line up solid and
stranded conductors,
and crimp them.
1. Twist the stranded
conductor around the
solid conductor at least
three times.
2. Bend the tip and solder it.
Make sure no lead wire
sticks out.
3. Overlap more than half of the
width and twist them at least
twice.

NOTES:
• If the lead wire with a connector is short, extend it using an interconnecting cable.
• Connectors have polarity, so pay attention and connect properly. If connected incorrectly, the
device won’t work.
Keep the number of connections as
low as possible when wiring.
After connecting wires, make sure to check
for breaking or insuffi cient connection.
Especially when connecting a wire in the
middle of wiring, either crimp it with a crimp
sleeve or solder it, and then insulate it by
covering with an insulating tape.
Just twisting wires may cause poor connection,
or the surface of the wires may get oxidized to
cause a loose connection, leading to
malfunctioning or failure.
