GRT1-series EtherCAT Communication Unit - Operation Manual
Observe the following precautions when using the Unit.
Power Supply
•
Always use the power supply voltage specified in this manual. An incorrect voltage may result in
malfunction or burning.
•
Take appropriate measures to ensure that the specified power with the rated voltage and
frequency is supplied. Be particularly careful in places where the power supply is unstable. An
incorrect power supply may result in malfunction.
•
Always turn OFF the power supply to the PLC, Slaves and other Units before attempting any of
the following. Not turning OFF the power supply may result in malfunction or electric shock.
•
Assembling any Units (Expansion Units).
•
Removing or attaching the terminal blocks or connectors to Slave.
•
Replacing parts (e.g., relays).
•
Setting the DIP switches and rotary switches.
•
Connecting cables or wiring the system.
Installation
•
Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any
static build-up. Not doing so may result in malfunction or damage.
•
Make sure that the terminal blocks, communication cables, and other items with locking devices
are properly locked into place. Improver locking may result in malfunction.
•
Mount the Units securely using DIN rail.
•
Make sure that all Slave mounting screws and cable connector screws are tightened to the torque
specified in this manual. Incorrect tightening torque may result in malfunction.
•
Make sure that all terminal block screws are tightened to the torque specified in this manuals.
Incorrect tightening torque may result in fire, malfunction, or failure.
•
Always use the specified communication cables and connectors.
•
Do not extend connection distances or the number of connected nodes beyond the ranges given
in the specifications.
•
When there are multiple systems, keep the cables unbundled and separated by at least 5 mm to
prevent unstable operation due to interference.
Wiring
•
Turn the power on after checking that the wiring and switch settings are correct.
•
Use the correct wire tools to wire the Unit.
•
Confirm the polarity of all terminals before wiring them.
•
Do not allow foreign matter to enter the Units when wiring and installing the Units.
•
Observe the following precautions when wiring the communication cable.
•
Separate the communication cables from the power lines or high-tension lines.
•
Do not bend the communication cables past their natural bending radius.
•
Do not pull on the communication cables.
•
Do not place heavy objects on top of the communication cables.
•
Always lay communication cable inside ducts.
•
Turn OFF the power of PLC and all the Slaves berofe wiring the communication cables.
•
Do not apply voltages to the Input Slaves in excess of the rated input voltage. Excess voltage or
loads may result in burning.
•
Do not apply voltages or connect loads to the Outputs Slaves in excess of the maximum switching
capacity. Excess voltage or loads may result in burning.
