Mounting The D4X5-2 / Cx32-2 - Siemens SIMOTION D4x5-2 Commissioning And Hardware Installation Manual

Installing
3.4 Alternative mounting position
Note
Mounting positions other than those described in this document are not permissible!
To achieve a low overall height with SINAMICS S120 power units, use SINAMICS S120
booksize compact power units or Power Modules in blocksize format connected via the CUA31/
CUA32 Control Unit Adapter.
Heat dissipation
If SIMOTION D4x5‑2 Control Units are mounted horizontally, a double fan / battery module is
required as in the standard mounting position.
The double fan / battery module is always contained in the scope of delivery of the Control
Unit for the SIMOTION D4x5‑2.
Danger of injury or damage to property due to high surface temperature
SIMOTION D4x5‑2 Control Units can have a high surface temperature particularly on the
aluminum front and the top of the module especially with the "horizontal" installation type.
Perform a module and cable replacement only when the module has cooled down.
The ventilation spaces of 80 mm must be complied with, see Fig. "Installation of the
SIMOTION D4x5-2 in a horizontal position". The control cabinet cooling concept must also
ensure that the maximum air inlet temperature and the ambient temperature do not exceed
55° C.
