Rack Installation

The BDx Module is intended for rack mount installations only and is designed to fit in standard 19-inch EIA equipment racks. The BDx Module product is designed to fit in one rack-unit (1U). Additional support, other than that provided by the front panel, is required. Fixed rear support rails are provided, which can be adjusted at time of installation to fit a variety of equipment rack depths. These included rails are designed to mate to inserts on the BDx Module side panels using included hardware. Alternatively, angle slides or cross beam supports can be used to securely fasten the product to the rack and support the rear weight. The unit should be horizontally mounted.

Cooling Requirements

Each BDx Module is cooled by suitable fans exhausting warm air to the rear of the cabinet. Fresh air intake is from the sides of the cabinet allowing two or more BDx Module to be stacked without any clearance required. Equipment racks should be equipped with fans or blowers to remove heat generated by the power supplies. Magna-Power recommends fresh air intake at the bottom of the cabinet and exhaust fans at the top pulling air out of the cabinet.

The BDx Module features integrated fans that pull in cool air from sides and exhausts warm air from the rear. Air intake from only the sides of the product allow two or more BDx Module to be stacked with zero clearance between units. Equipment racks housing the BDx Module should be equipped with either an open back, back with grills, or closed back with cabinet fans to remove heat generated by the BDx Module. For fully enclosed cabinets, Magna-Power recommends fresh air intake from the bottom of the cabinet and exhaust at the top.

For cabinet fans to be effective, the ambient intake air temperature outside the rack must be less than the air temperature inside the rack. The BDx Module is rated for 50°C ambient operating temperature. In the case of rack installation, this corresponds to the temperature inside the rack and adequate cooling measures must be taken to ensure the rack’s internal temperature stays below 50°C.

The following table provides Magna-Power’s recommended per unit cabinet air flow when installing the BDx Module in a fully enclosed cabinet:

Note

The table above accounts for only a single Accessory. When sizing cabinet fans, it is necessary to account for the heat produced by all the products in the cabinet.

Caution

Do not block the air intake on the front or sides of the instrument, nor the exhaust at the rear of the instrument. Blocking these vents could cause the product to overheat. The recommended minimum clearances are 2 inches (5.1 cm) along the sides and back.
