Machine Room Preparation
When preparing the machine room, consider:
• Machine room environment
• Ethernet and internet access
Environmental Considerations
• Ambient temperature should remain within 32° to 104° Fahrenheit (0° to 40° Celsius).
Temperatures outside these guidelines may be tolerated, but will shorten equipment life.
Adequate ventilation is required. Air conditioning may be necessary.
• The air in the machine room should be free of excessive dust, corrosive elements, and
excessive moisture. A NEMA 4 or NEMA 12 enclosure can help meet these requirements if
machine room conditions are inadequate.
• Very high levels of radio frequency (RF) radiation from nearby sources should be avoided.
RFI may interfere with controller components, degrading elevator performance. Using
hand-held communication devices close to the controller may also cause interference.
Interference from permanently installed radio transmitting antennas is not common.
• Power line voltage fluctuation should not be greater than ±10%.
• If any areas in the machine room are subject to vibration, they should be avoided or rein-
forced to prevent equipment from being adversely affected.
