Minimum Spacing
Maintain spacing from enclosure walls, wireways, and adjacent equipment. Allow
50 mm (2 in.) of space on all sides, as shown. This provides ventilation and
electrical isolation.
ATTENTION: When attaching the controller, power supply, and I/O modules,
make sure the bus connectors are securely locked together to be sure of
proper electrical connection.
This equipment is not resistant to sunlight or other sources of UV radiation.
ATTENTION: During panel or DIN-rail mounting of all devices, be sure that all
debris (such as metal chips or wire strands) is kept from falling into the
controller. Debris that falls into the controller could cause damage while the
controller is energized.
