TROUBLESHOOTINGAPPENDIX
(3) Installation precautions
(a) Install a base unit on a flat surface.
If the surface is not flat, the printed circuit board is distorted, resulting in
malfunction of the modules mounted.
(b) If there is a vibration source, such as an electromagnetic contactor or no fuse
breaker, separate the control panel or keep enough clearance from the vibration
source to install the programmable controller.
In addition, keep the clearances shown below between the programmable
controller and devices (such as contactors and relays) to avoid being affected by
radiated noise or heat.
• In front of the programmable controller: 100mm or more
• On the right or left of the programmable controller: 50mm or more
(c) When installing a programmable controller to a control panel, do not mount any
module in the rightmost slot of the base unit.
Before uninstalling, remove the module mounted in the rightmost slot of the base
unit.
