4-2 Diagnostics, Troubleshooting, and Start-Up Guidelines
• If a user has Rack access, no other user can make changes in that rack. All other
users will be limited to monitoring tasks and variables.
• Each user can monitor up to 16 COMMON and/or LOCAL variables.
• A maximum of 32 LOCAL variables per UDC module can be monitored, regardless
of the number of users.
• A maximum of 16 variables per rack can be forced.
Appendix G describes the type of access required by the user in order to carry out
common Programming Executive operations. Refer to the AutoMax Programming
Executive instruction manual for more specific information.
4.2 Environmental Requirements
The installation must meet the following requirements:
Ambient Temperature
• Open chassis: 0 to 50° C (32 to 122° F)
Enclosed chassis: 0 to 40° C (32 to 104° F)
Cooling
• Air for cooling must be of sufficient quality and flow to avoid recycling the heated
exhaust air back into the drive air inlets.
Relative humidity
• 5 - 95%, non-condensing
Altitude
• 1000 meters (3300 feet) above sea level.
Higher altitudes require derating.
Air Quality
• Clean
No flammable vapors, chemical fumes, or oil vapor.
Clearances
• Must allow access to the equipment within the cabinets for inspection,
maintenance, and replacement.
• Must provide non-restricted air flow to and from the intake and exhaust openings.
See the SA3100 Power Modules instruction manual (S-3058) for more detailed
information about installation requirements.
