[Wiring Instructions]
• Before mounting or wiring the module, make sure to shut off all of the external power supply.
Failure to do so may cause electric shocks or damage the module.
• When turning on the power and operating after mounting or wiring the module, make sure to
install the accessory terminal covers to the product.
Otherwise, it may cause electric shocks.
• Make sure to place the communication cables and the power cables 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 can be unstable,
moved and pulled inadvertently. This may damage the module and the cables, or cause the
module malfunction due to unsecured cable connections.
• When disconnecting the communication cables and the power cables, do not pull the cables.
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 before removing the cable.
If a cable is pulled while being connected, it may cause the module malfunction or damage the
module and the cable.
• Do not bundle the control line and the communication cables together with or lay it close to the
main circuit or power line. As a guideline, lay the control line and the communication cables at
least 100mm (3.94") or more away from the main circuit or power line.
Noise may cause malfunctions.
• Before connecting twisted pair cables, the ground pin brush grounded via a resistor enables
discharging static electricity on the cables effectively. This can prevent the electrostatic
discharge to the product.
