2.2 Installing the SIMATIC Box PC 620
The SIMATIC Box PC 620 can be operated in all the usual fitting positions. It is
particularly suitable for fitting in consoles, switch boards and control panels.
The SIMATIC Box PC 620 with AC power supply meets the requirements for a
fire enclosure to EN60950. it can therefore be fitted without an additional fire
enclosure.
The SIMATIC Box PC 620 with DC power supply is an open device (right device
side); therefore the mounting must meet the requirements of a fire enclosure.
Please note the following points when installing the PC:
•
Avoid extreme ambient conditions as far as possible. Protect your PC from
dust, moisture, and heat.
•
Keep the PC out of direct sunlight.
•
Mount the PC as safely as possible to prevent any danger (for example, by
falling over).
•
The clearance around the housing must be at least 100 mm at the front and
rear, so that the PC is sufficiently ventilated.
• Make certain that the ventilation slots for the housing are not covered.
• Observe the permissible fitting positions without fail when installing the
systems.

Warning
If the systems are installed in a non-permissible fitting position, the approvals
pursuant to UL 1950, UL 508 and EN60950 are no longer valid!
