CAUTION
De-energize the entire system
The system could start up unexpectedly while you are connecting the
devices.
• Select the wire and DC power supply to keep input voltage in the range of 21.6 to 26.4VDC
including the ripple voltage and voltage spike to the safety signal module which is
measured at the input connector.
• When wiring in the safety signal module, be sure that it is done correctly by checking the
product rated voltage and the terminal layout. Connecting a power supply that is different
from the rating or incorrectly wiring the product could result in fire or damage.
• Be sure to use a shield cable for connection of the CTRL connector and external
equipment, and avoid running it close to or bundling it with the power and main circuit
cables to minimize the influence of electromagnetic interface. (Separate them more than
200mm (0.66ft.) away.)
• Connect the shield wire of the connection cable to the FG terminal of the external
equipment.
• Securely tighten
the cable connector fixing screws and fixing mechanisms. Insufficient
fixing may lead to cables combing off during operation.
• Be sure to wire the cables when power is off. Not doing so may damage the circuit of
modules.
• Wire the cable correctly. The safety function may not work correctly by wrong wiring.
Please make sure the wiring and test sufficiently.
