WARNING
● To avoid the risk of an electric shock, turn o the
power supply and use a tester or similar device to
ensure that no power is supplied to a cable to be
connected, before carrying out wiring work.
● Do not operate the product in the presence of
ammable or explosive gases or vapors. To do so is
highly dangerous.
● Use of the product ignoring the specications may
cause overheating or damage. Before turning on
the power, ensure the following:
• Power supply voltage and input signal value
applied to the product should meet the required
specications.
• The external wiring to the terminals and wiring to
ground are as specications.
Wiring should be connected to the terminals on the socket of the
product. The terminals for external connections are of M3 screws.
Use crimp-on terminal lugs for connections to the terminals.
• Recommended cables: A nominal cross-sectional area of
