E2860

The clearance needed for proper ventilation and heat dissipation is as follows:

The power and heat dissipation values are as follows:

The power supplies in the E2860 controller shelf support voltages in the 200V to 240V range. The power supplies meet standard voltage requirements for both North American (USA and Canada) operation and worldwide operation. The power supplies use standard industrial wiring with line-to-neutral power connections or line-to-line power connections.

Keep this information in mind when you prepare the installation site:

• Protective ground – Site wiring must include a protective ground connection to the AC power source.

  Note: Protective ground is also known as safety ground or chassis ground.

• Circuit overloading – Power circuits and associated circuit breakers must provide enough power and overload protection. To prevent damage to the drive tray, isolate its power source from large switching loads, such as air-conditioning motors, elevator motors, and factory loads.
• Power interruptions – The controller shelf can withstand these applied voltage interruptions:
  • Input transient – 50 percent of the nominal voltage
  • Duration – One half-cycle
  • Frequency – Once every 10 seconds
• Power failures – If a total power failure occurs, the controller shelf automatically performs a power-on recovery sequence without operator intervention after the power is restored.

Each power supply contains two 16A slow-blow fuses.

These numbers can vary significantly, depending upon the drives tested in the particular configuration.

Power factor correction is applied within the power supply, which maintains the power factor of the E2860 controller shelf at greater than 0.95 with nominal input voltage.

Each E2860 controller shelf is shipped with two AC power cords, which fit the standard AC outlets in the destination country. Each AC power cord connects one of the power canisters in the controller shelf to an independent, external AC power source, such as a wall receptacle, or to any uninterruptible power supply (UPS).
