3. Preparations

This product is guaranteed to operate in a temperature range of 0–40 degrees. If only this product is being

mounted in an EIA standard rack, multiple units can be mounted without leaving space between them. If this

product is being mounted in an EIA standard rack together with other devices, heat from each device might

cause the temperature inside the rack to rise, preventing this product from operating to its full potential. To

prevent heat buildup inside this product, you must observe the following conditions when mounting it in a rack.

• If this product is mounted together with devices that tend to become hot, such as power amps made by

other manufacturers, leave 1U or more of space between this product and other devices. Install a

ventilation panel in this space or leave it open to ensure sufficient airflow.

• Since this product takes in air at the front and exhausts it at the back, you should not rack-mount it

together with devices that take in air at the back and exhaust it at the front.

• Leave the back panel of the rack open, and keep the rack at least 10 cm away from the wall or ceiling to

ensure sufficient airflow. If the back panel of the rack cannot be left open, attach a commercially available

fan kit or other forced air exchange device. If a fan kit is installed, closing the back panel of the rack might

increase the heat dissipation effect in some cases. For details, refer to the owner's manual of your rack

and fan kit.

Install the included filter elements and grills. Note that the size of the filter elements differs between left and

right. The grills are held in place magnetically, and can be easily attached.

Fit the filter elements into the brackets of the unit; then attach grill "L" to the left side of the unit's front panel and

attach grill "R" to the right side of the front panel.
