Installation Precautions

Video Monitor
(When using the recommended F150-M09)
Heed the following precautions to prevent noise interference if the
video monitor case is metallic, because it is connected to the 0V line
in the internal circuits.
• Do not ground the video monitor.
• Do not ground the metallic part of the connector.
• Secure the video monitor with plastic screws if it is being
mounted to a metallic surface.
2-Dimensional Code
• The blank margin (quiet zone) is necessary around 2-dimen-
sional codes. Ensure a margin of at least four cells around both
data matrix and QR codes except for QR codes in Pattern mode.
A margin of only one cell is sufficient with QR codes in Pattern
mode.
• Adjust the only one reading code to be within the field of vision.
Reading can not be performed correctly if more than one code
are on a screen.
• Adjust the field of vision of a camera for the 2-dimensional code
to be at least 5 pixels per cell.
RESET Terminal
Do not use RESET input immediately after power is turned ON.
When using RESET input to synchronize execution timing, wait at
least 1 s after turning ON the V530-R150 power supply before turning
ON the RESET terminal.
