Chapter 1 General Information
Environmental Conditions
The controller must accept nominal plant power of 2400V, 3300V, 4200V,
4800V, 5500V, 6600V, 6900V (+5/-15%), or 7200V (+0/-15%), 3 PH,
50/60 Hz (± 3%).
The standard controller must operate in an ambient temperature range of
0…40 °C (32…104 °F) with a relative humidity of up to 95% (noncondensing).
Higher ambient temperature conditions are supported with factory assistance.
Store the equipment in an environment with an ambient temperature range of
-40…+85 °C (-40…+185 °F).
If storage temperature fluctuates or if humidity exceeds 85%, space heaters
must be used to prevent condensation. The equipment must be stored in a
heated building which has adequate air circulation.
Rockwell Automation products are built using materials that comply with
Class 1: Industrial Clean Air sulfur environments as defined in IEC Standard
60654-4 (Operating Conditions for Industrial-Process Measurement and
Control Equipment), and G1 as defined in ISO-S71.04-1985 (Environmental
Conditions for Process Measurement and Control Systems: Airborne
Contaminants).
High Altitude Application
The equipment operates at altitudes from 0…1000 m (0…3300 ft) above sea
level, without derating. For applications above 1000 m (3300 ft), the maximum
current and basic impulse levels (BIL) of the controllers shall be derated, and
vacuum contactors may be compensated for operation at the specified altitude
(see publication
).
WARNING:
Do not store the equipment outside.
