DESIGN PRECAUTIONS
•Some failures of the Multi-Drop Connection Unit or cable may keep the
outputs on or off.
An external monitoring circuit should be provided to check for output signals
which may lead to a serious accident.
Not doing so can cause an accident due to false output or malfunction.
•If a communication fault (including cable disconnection) occurs during
monitoring on the GOT, communication between the GOT and PLC CPU is
suspended and the GOT becomes inoperative.
A system where the GOT is used should be configured to perform any
significant operation to the system by using the switches of a device other
than the GOT on the assumption that a GOT communication fault will occur.
Not doing so can cause an accident due to false output or malfunction.
•
Do not use the Multi-Drop Connection Unit as the warning device that may
cause a serious accident.
An independent and redundant hardware or mechanical interlock is required to
configure the device that displays and outputs serious warning.
Failure to observe this instruction may result in an accident due to incorrect
output or malfunction.
DESIGN PRECAUTIONS

DESIGN PRECAUTIONS
•Some failures of the Multi-Drop Connection Unit or cable may keep the
outputs on or off.
An external monitoring circuit should be provided to check for output signals
which may lead to a serious accident.
Not doing so can cause an accident due to false output or malfunction.
•If a communication fault (including cable disconnection) occurs during
monitoring on the GOT, communication between the GOT and PLC CPU is
suspended and the GOT becomes inoperative.
A system where the GOT is used should be configured to perform any
significant operation to the system by using the switches of a device other
than the GOT on the assumption that a GOT communication fault will occur.
Not doing so can cause an accident due to false output or malfunction.
•
Do not use the Multi-Drop Connection Unit as the warning device that may
cause a serious accident.
An independent and redundant hardware or mechanical interlock is required to
configure the device that displays and outputs serious warning.
Failure to observe this instruction may result in an accident due to incorrect
output or malfunction.
DESIGN PRECAUTIONS

5. Installation
5.1 Installed with DIN Rail
Install the multi-drop connection module with its hook (1 place) using the DIN rail.
•Applicable DIN rail DIN46277 (width: 35mm)
(Install the DIN rail with screws at intervals of 150mm.)
5.2 Directly Installed to Panel
Install the multi-drop connection module to the panel using φ4.5mm holes (2 places).
5.3 Caution for compliance with EMC Directive
Programmable logic controllers are open-type devices that must be installed and used within conductive control boxes. Please use the Multi-Drop Connection Unit while
installed in conductive shielded control boxes. Please secure the control box lid to the control box (for conduction). Installation within a control box greatly affects the safety of
the system and aids in shielding noise from the Multi-Drop Connection Unit.
6. Wiring
6.1 Power Supply Wiring
Connect the power supply cable with connectors (included) and the 24VDC terminal of the external power supply.
6.2 Wiring and Terminating Resistor Setting
6.2.1 For 1 pair wiring
Make sure to ground a twisted pair cable by applying Class D Grounding (100Ωor less).
*1 The terminating resistor 110Ωis built in the multi-drop connection module and GOT (GT10,GT11).
Make sure to set the terminating resistor to both ends of the line.
For GT15 or GT16, external wiring is required. Set the terminating resistor of the GOT that is not at the end of the line to "OPEN".
