The D400 can be installed in a standard 19-inch rack or substation panel.

Rack Mounting

The D400 mounts directly into an industry-standard 19-inch [482.6 mm] equipment mounting rack with EIA universal mounting rail hole spacing.

The top cover of the D400 can get hot during peak operation. Ensure that there is at least 1U (1.75 inch [44.45 mm]) of free space above the D400 unit for proper ventilation.

When the unit is operating above the 50 °C ambient temperature, safe handling precautions are recommended to prevent burns.

1.Position the D400 in the rack.

2.Holding the D400 firmly in the rails of the mounting rack, insert and tighten the four rack screws.

The recommended tool torque settings for zinc-plated mounting screws are:

–10-32 UNF screws use 22.2 in-lb [2.50 Nm]

–12-24 UNC screws use 31.0 in-lb [3.51 Nm]
