z
Handling abnormalities
Turn off the power immediately in the following cases. Using the unit in an abnormal con-
dition could cause fire, electric shock, or accident.
• Contact the nearest KEYENCE office for repair.
• If liquid including water, chemicals or debris enters the unit.
• If a metal contacts the connector.
• If the unit is dropped or the case is damaged.

z
Handling
• The DV-90 uses 24V DC for the supplied power voltage. Use of any other power supply
than this may damage the DV-90.
• The 5V DC power voltage supplied from the pin 9 of the 9-pin D-sub power supply is the
supplied power dedicated for the Keyence code reader. Do not use it for any other
devices than for the Keyence code reader. Otherwise, the connected device may be
damaged.
The maximum current that can be supplied to the connected code reader is 1100 mA.
Ensure that the sum of the current consumption of the code reader connected to the DV-
90 stays under this value.
However, when the ambient temperature exceeds 40 °C, the maximum power current that
can be supplied is 850 mA.
• Be sure to turn off the power of the DV-90 and of the connected devices when you plug/
unplug the cable. Otherwise, the DV-90 and the connected devices may be damaged.
• Isolate the cable from devices that generate high frequency, power supply lines or power
lines. Otherwise, noise could cause malfunction or accident.
• Do not damage, pull or heat the cable.

z
Operating environment/condition
• Disconnect the power supply unit at the time of maintenance.
• Do not wipe the DV-90 with benzene, thinner or alcohol. Doing so could change the color

mild detergent, then rub with a dry cloth.
