[Wiring Instructions]
!
CAUTION
•
Use crimp-contact, pressure-displacement or soldering to wire the connectors for external
connections properly using the manufacturer-specified tools.
If the connection is incomplete, it may cause the module to short circuit, catch fire, or
malfunction.
•
Do not connect the AUI cable when the power to the station in which the module is loaded is on.
•
Make sure to place the communication and power cables to be connected to the module in a
duct or fasten them using a clamp. If the cables are not placed in a duct or fastened with a
clamp, their positions may be unstable or moved, and they may be pulled inadvertently.
This may damage the module and the cables or cause the module to malfunction because of
faulty cable connections.
•
Tighten the terminal screws using the specified torque. If the terminal screws are loose, it may
cause the module to short-circuit, malfunction or fall off. If the terminal screws are tightened
excessively, it may damage the screws and cause the module to short-circuit, malfunction or fall
off.
•
When disconnecting the communication and power cables from the module, do not pull the
cables by hand. When disconnecting a cable with a connector, hold the connector to the module
by hand and pull it out to remove the cable. When disconnecting a cable connected to a terminal
block, loosen the screws on the terminal block first before removing the cable. If a cable is
pulled while being connected to the module, it may cause the module to malfunction or damage
the module and the cable.
•
Be careful not to let any foreign matter such as wire chips get inside the module. They may
cause fire, as well as breakdowns and malfunctions of the module.
•
A protective sheet is pasted on the upper part of the module in order to prevent foreign matter
such as wire chips to get inside the module while wiring.
Do not remove this protective sheet during wiring work. However, be sure to remove the
protective sheet before operating the module to allow heat radiation during operation.
•
Solder the coaxial cable connectors properly. Incomplete soldering may result in malfunctions.
