7.3 Enclosure and securing of the modules.
7.3.1 Ambient characteristics of the cabinet.
The U70 module must be installed inside an electrical cabinet with a protection rating of IP54
or higher. The ventilation for the electrical cabinet must be enough to dissipate the heat
generated by all the devices and components working inside. The interior temperature of
the cabinet must not exceed 55ºC (113ºF) while the unit is running.
Dissipated power.
The modules generate heat and when trying to decide whether the electrical cabinet needs
external cooling or not, one must know the power dissipated by each one of its modules.
7.3.2 Cabinet design.
When attaching the module, the following requirements must be met.
• Place the modules in a vertical position.
• To secure the module, use the holes and slots made for that purpose. Vibrations should
be avoided. If necessary use securing means made of a material which absorbs or
minimizes vibrations.
• Respect the minimum distances recommended between the enclosure walls and the
central unit to let the air flow and improve heat dissipation.
7.3.3 Ventilation.
Leave a clearance of at least 50 mm (1.97 inches) above and below the module as well as
on the side (where the ventilation slots are located) to allow air to flow and heat to dissipate.
