5. Wiring

Before installation or wiring, be sure to shut off all phases of the external
power supply used by the system.
Failure to do so may cause electric shocks or damage the product.
Solder the coaxial cable connector properly. Incomplete soldering may
cause a malfunction.
Be sure there are no foreign substances such as sawdust or wiring debris
inside the module. Such debris could cause fires, damage, or erroneous
operation.
Make sure to place the communication and power cables into a duct or
fasten them using a clamp.
Cables not placed in the duct or not clamped may hang or shift, allowing
them to be accidentally pulled, which may cause a module malfunction and
cable damage.
When removing the communication cable or power cables from the module,
do not pull the cable. When removing the cable with a connector, hold the
connector on the side that is connected to the module. When removing the
cable connected to the terminal block, first loosen the screws on the terminal
block. Pulling the cable that is still connected to the module may cause
malfunction or damage to the module or cable.
Please refer to the reference manual of used master module for the wiring for
network system.
Please wire IN/OUT or SD/RD of the connector for the cable correctly.
Please do loopback test, the set confirmation test, and the bureau order
confirmation test after wiring. It might be generated that a baton abnormal
passing cannot be generated when miswiring and the downed bureau which
cannot do the loopback of an arbitrary bureau do the row again even by the
reclosing of the power supply.
