Please observe the following precautions to prevent failure to operate, malfunctions, or
undesirable effects on product performance.
Installation of the Product
Installation Site
Do not install the product in locations subjected to the following conditions:
• Ambient temperature outside the rating
• Rapid temperature fluctuations (causing condensation)
• Relative humidity outside the range of 35 to 85%
• Presence of corrosive or flammable gases
• Presence of dust, salt, or iron particles
• Direct vibration or shock
• Reflective sensor of intense light (such as other laser beams or electric arc-welding
machines)
• Direct sunlight or near heaters
• Water, oil, or chemical fumes or spray
• Strong magnetic or electric field
Component Installation and Handling
Power Supply and Wiring
• To extend the output cables of amplifier units, shielded cables of the same specifi-
cations as the output cables must be used.
• When using a commercially available switching regulator, make sure that the FG
terminal is grounded.
• If surge currents are present in the power lines, connect surge absorbers that suit
the operating environment.
• When using two or more amplifier units or calculating units, make sure that the lin-
ear GND line of the amplifier units are connected to each other.
• Before turning ON the power after the product is connected, make sure that the
power supply voltage is correct, there are no incorrect connections (e.g. load short-
circuit) and the load current is appropriate. Incorrect wiring may result in breakdown
of the product.
• The cables must be 10 m or shorter in total length, for both sensor head and ampli-
fier units. To extend the cable from the sensor head, an optional extension cable
(ZX2-XC
R) must be used. For extension of the cable of amplifier units, shielded
cables of the same type must be used.
• When using calculating units, make sure that the linear GND lines of the amplifier
units are connected to each other.

undesirable effects on product performance.

• When using a commercially available switching regulator, make sure that the FG

• If surge currents are present in the power lines, connect surge absorbers that suit
the operating environment.
• When connecting two or more amplifier units by using calculating units, make sure
that the linear GND lines of the amplifier units are connected to each other. Supply
power to all connected amplifier units at the same time.
• Before turning ON the power after the product is connected, make sure that the
power supply voltage is correct, there are no incorrect connections (e.g. load short-
circuit) and the load current is appropriate. Incorrect wiring may result in breakdown
of the product.
• The ferrite core accessory must be attached to the sensor head cable before use.
(For how to attach the ferrite core, see pages 24 and 28.)
• The cables must be 10 m or shorter in total length for amplifier units. For extension
of the cable of amplifier units, shielded cables of the same type must be used. To
extend the cable from the sensor head, an optional extension cable (ZX2-XC
R)
must be used. Only one extension cable can be used.
• When using calculating units, make sure that the linear GND lines of the amplifier
units are connected to each other.
