A4.1. Installing the Base Module
The DTSXL System is designed to be attached to 19-inch racks. Observe the following
precautions when installing a DTSXL System to cabinets, control panels, etc.

Installation Direction
The DTSXL System is designed to be cooled by natural air. Install a DTSXL System so
that the ventilation air flows upward from its bottom to its top as shown below.
Figure Installing the Base module
CAUTION
- Be sure to turn off the power before installing or removing the base module.
- Do not install the unit in a manner that blocks the ventilation holes on the top and
bottom.
- To prevent the cooling air current from being blocked, be sure to place the unit at
least 100 mm away from other devices.
- Do not expose the unit to direct sunlight
- All access to the DTSXL System is from the front. Reserve a space of 100 and 150
mm from the front panel of the unit to the cabinet door to provide enough space for
the cables. (The minimum bending radius varies with cable material. Check the
wire specification.)
