Description
Tolerance
Relative humidity
•
Normal operation ensured in relative humidity range of 5% through 90%, noncondensing.
•
Short-term operation ensured in relative humidity range of 5% through 93%,
noncondensing.
NOTE: As defined in NEBS GR-63-CORE, Issue 3, short-term events can be up to 96
hours in duration but not more than 15 days per year.
Temperature
•
Normal operation ensured in temperature range of 32° F through 104° F (0° C through
40° C).
•
Nonoperating storage temperature in shipping container: –40° F through 158° F (–40° C
through 70° C).
Seismic
Designed to comply with Zone 4 earthquake requirements per NEBS GR-63-CORE, Issue 3.
NOTE: Install the PTX10001-36MR only in restricted areas, such as dedicated equipment rooms
and equipment closets, in accordance with Articles 110-16, 110-17, and 110-18 of the National
Electrical Code, ANSI/NFPA 70.
General Site Guidelines
Efficient device operation requires proper site planning and maintenance. It also requires proper layout
of the equipment, rack or cabinet, and wiring closet.
To plan and create an acceptable operating environment for your device and prevent environmentally
caused equipment failures:
• Keep the area around the chassis free from dust and conductive material, such as metal flakes.
• Follow prescribed airflow guidelines to ensure that the cooling system functions properly. Ensure
that exhaust from other equipment does not blow into the intake vents of the device.
• Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the
equipment. Static discharge can cause components to fail completely or intermittently over time.
