This section describes how to install a DS-Bus network.
This section provides basic precautions for installing a DS-Bus network.
Precautions for Installing a Network
•
When installing a DS-Bus network, observe proper safety measures and follow all applicable
standards. (Refer to JIS X5252 or
Electric Installation Technical Standards
.)
We recommend that you request installation from a specialist who is qualified in safety measures and
standards.
•
Do not place any DS-Bus network devices near any devices that generate noise.
If no other suitable location is available, place the device or devices in a metal case or take other
measures to reduce ambient noise.
Precautions for Installing Communications Cables
•
Check the following conditions for the communications cables in the network.
•
Are there any disconnections?
•
Are there any short circuits?
•
Are there any problems with connector connections?
•
When connecting to the communications connector on each device, be sure to insert the wires until
they lock into place in the communications cable connector.
•
Separate communications cables from high-voltage power lines and install them in ducts.
•
Do not wire communications cables near devices that generate noise.
•
Do not wire communications cables in high-temperature, high-humidity environments.
•
Use in locations free of dirt, oil mist, and other foreign matter.
•
There is a limit to the bending radius of communications cables. Refer to the specifications for your
communications cables for information on allowable bending radii.
•
You can connect up to eight Distributed Sensor Units to one Sensor Communications Unit.
•
Keep the total length of DS-Bus communications cables (L1 + L2 + ... + Ln) to within 30 m.
•
Turn ON the DS-Bus termination setting switch for the last Distributed Sensor Unit on the DS-Bus
network. Turn this switch OFF for all other Distributed Sensor Units.
Prepare the following equipment.
