1.3 Installation

A visual inspection of this product for possible damage occurred during shipment is
recommended before installation. It is your responsibility to ensure that qualified mechanical
and electrical technicians install this product.

If there is danger of serious accident resulting from a failure or defect in this unit, power off the
system and separate the electrical connection of the device from the system.

The unit is normally supplied without a power supply switch or a fuse. Use power switch and fuse
as required.

Be sure to use the rated power supply voltage to protect the unit against damage and to prevent
failure.

Keep the power off until all of the wiring is completed so that electric shock and trouble with the
unit can be prevented.

Never attempt to disassemble, modify or repair this unit. Tampering with the unit may results in
malfunction, electric shock or fire.

Do not use the unit in combustible or explosive gaseous atmospheres.

During putting equipment in hole on the metal panel while mechanical installation some metal
burrs can cause injury on hands, you must be careful.
