SMC Networks IZE11 Operation Manual page 7

The direct-current power supply to combine should use UL authorization power supply which is the class 2 power
supply based on UL 1310 or the power supply is using the transformer of a class 2 based on UL 1585.
Environment
Do not use the product in an atmosphere containing corrosive gas, chemicals, seawater, water or vapor,
or in a place where there is a possibility of adhesion of those substances to the product.
It can cause failure or malfunction.
Avoid exposure of this product to direct sunlight.
Use sunshades if the product is exposed to direct sunlight.
Otherwise it can cause failure or malfunction.
Do not use in a place where water, oil or chemicals splashes.
Otherwise it can cause failure or malfunction.
Do not use a monitor nearby a place where electric surges are generated.
Internal circuit elements of the monitor can deteriorate or break when equipment generating a large surge
(electromagnetic lifter, high frequency induction furnace, motor, etc.) is located near the monitor. Provide surge
preventives, and avoid interference.
Do not apply the monitor to the load that generates electric surge voltage.
Relays or solenoid values generate electric surge voltage. When applying the monitor to drive these loads directly,
use the product equipped with surge absorber.
The product is not resistive to a lightning surge defined in CE marking. Take measures to protect
against a lightning surge at the load side.
Prevent foreign matter such as remnant of wires from entering this product.
Take proper measures for the remnant not to enter the monitor in order to prevent failure or malfunction.
Do not expose the monitor to vibration and impact.
Otherwise it can cause damage or malfunction.
Follow the specified ranges of the operating fluid and maintain ambient temperatures.
The ambient temperature should be in the range of 0 to 50 °C.
If the temperature is out of the specified range, resin parts may become fragile and be broken or deformed by head,
causing malfunction.
Take preventive measures against freezing. Do not use the monitor in a place where temperature suddenly
changes even if it stays within the specified range.
Do not expose the monitor to heat radiation from a heat source located nearby.
It can cause malfunction.
Adjustment and Operation
Do not short-circuit the load.
The monitor indicates the error status when a load is short-circuited. However, excess current can damage the
monitor.
Do not press the buttons with a sharp object.
It can cause damage to the setting buttons.
A warm-up time of 20 to 30 minutes is needed for detection of low potential.
The indication drifts about 1% soon after the power is on.
Do not touch the LCD during operation.
The indication on the LCD changes due to static electricity.
Maintenance
Before performing maintenance, make sure to turn off the power supply.
Otherwise an unexpected operation of the system component can occur.
Perform maintenance and check regularly.
Otherwise an unexpected malfunction of the system can occur due to a malfunction of the monitor.
Perform a proper functional check after maintenance.
Stop operation when an abnormality is observed such that the device does not work properly.
Otherwise an unexpected malfunction of the system component can occur.
Do not use solvents such as benzene or thinner to clean the monitor body.
It can damage the surface of the body and erase the indication on the body.
Use a soft cloth to remove stains. For heavy stains, use a cloth soaked with diluted neutral detergent and fully
squeezed, then wipe up the stains again with a dry cloth.
