Rack Mount Installation (Continued)

1.Enclosed Racks (Continued):

The ambient within the rack may be greater than room ambient. Installation should be such that the amount of air flow required for safe operation is not compromised. The maximum temperature for the equipment in this environment is 45C. Consideration should be given to the maximum rated ambient.

Installation should be such that a hazardous stability condition is not achieved due to uneven loading.

2.Open Racks: Make certain that the rack frame does not block the ventilation slots on the instrument cover. If the device is installed on sliders, check the unit when seated all the way into the rack to make certain that ventilation slots are not blocked.

Ventilation

Slots in the instrument cover are provided to allow ventilation for heat dissipation. To ensure safe, reliable operation, these openings must not be covered or blocked.

Disconnect Power

If any of the following events are noted, immediately disconnect the unit from the outlet and contact qualified service personnel:

1.If the power cord becomes frayed or damaged.

2.If liquid has been spilled into the device or if the device has been exposed to rain or water.
