Precautions for Safe Use
■
Handling with Care
Do not drop the NE1A-series Controller or subject it to excessive vibration or
me-chanical shock. The NE1A-series Controller may be damaged and may
not function properly.
■
Installation and Storage Environment
Do not use or store the NE1A-series Controller in any of the following loca-
tions:
• Locations subject to direct sunlight
• Locations subject to temperatures or humidity outside the range specified
in the specifications
• Locations subject to condensation as the result of severe changes in tem-
perature
• Locations subject to corrosive or flammable gases
• Locations subject to dust (especially iron dust) or salts
• Locations subject to water, oil, or chemicals
• Locations subject to shock or vibration
Take appropriate and sufficient measures when installing systems in the fol-
lowing locations. Inappropriate and insufficient measures may result in mal-
function.
• Locations subject to static electricity or other forms of noise
• Locations subject to strong electromagnetic fields
• Locations subject to possible exposure to radioactivity
• Locations close to power supplies
■
Installation and Mounting
• Use the NE1A-series Controller within an enclosure with IP54 protection
or higher according to IEC/EN 60529.
• Use DIN rail (TH35-7.5/TH35-15 according to IEC 60715) to install the
NE1A-series Controller into the control panel. Mount the NE1A-Series
Controller to the DIN rail using PFP-M End Plates (not included with the
NE1A-series Controller) to prevent it falling off the DIN rail because of
vibration.
• Space must be provided around the NE1A-series Controller, at least 5
mm from its side and at least 50 mm from its top and bottom surfaces, for
ventilation and wiring.
Contactor
Use contactors with a forcibly guided mechanism and monitor the auxiliary
NC contact to detect contactor failures. For feedback signals, use devices
with contacts capable of switching micro-loads of 4 mA at 24 VDC.
Other devices
Evaluate whether devices used are appropriate to satisfy the requirements of
the safety category level.
