z PLC Orientation

• Each Rack must be mounted in an upright position to provide proper cooling.

• Do not install a Rack in any of the following positions.

Precautions for Safe Use

Always use the standard installation method. A nonstandard installation will decrease heat dissi-

pation, and may delay the replacement notification signal (in particular for Power Supply Units

with Replacement Notification (CJ1W-PA205C)), or degrade or damage the internal elements.
