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.
Notes on Usage of UG520/UG420 100-200V AC Specifications
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.
