to UG520/UG420

When TB1 is used for wiring, refer to the following table.
The power source used must be within the allowable voltage fluctuation.
Use a power source with low noise between the cables or ground and the cable.
Use as thick a power cable as possible to minimize any drop in voltage.
Keep cables of 100V AC and 24V DC sufficiently away from high-voltage, large-current cables.

Generally, an isolating transformer improves noise resistance.  However, if the display unit is far away

from the secondary port of the transformer and noise gets mixed in, an isolating transformer becomes

unnecessary.

If any power voltage fluctuation caused by noise is expected, it is recommended that a voltage stabilizer

be used.

   Caution

•

Do not remove the dust-proof seal till you finish wiring in the panel.  If the seal is removed, conductor chips or other

foreign matter may enter the device to cause failure.

•

When you finished wiring in the panel, be sure to remove the dust-proof seal.
