4. General Safety Instruction for IT Equipment KISS 2U V2 MB_SBC– User's Guide (Version 1.00)
Additional safety instructions for DC power supply circuits
‰ To guarantee safe operation of devices with DC power supply voltages larger than 60 volts DC or a power consumption
larger than 240 VA, please observe that:
• the device is set up, installed and operated in a room or enclosure marked with “RESTRICTED ACCESS”, if there are no
safety messages on product as safety signs and labels on the device itself.
• no cables or parts without insulation in electrical circuits with dangerous voltage or power should be touched
directly or indirectly
• a reliable protective earthing connection is provided
• a suitable, easily accessible disconnecting device is used in the application (e.g. overcurrent protective device), if
the device itself is not disconnectable
• a disconnect device, if provided in or as part of the equipment, shall disconnect both poles simultaneously
• interconnecting power circuits of different devices cause no electrical hazards
‰ A sufficient dimensioning of the power cable wires must be selected – according to the maximum electrical
specifications on the product label – as stipulated by EN60950-1 or VDE0100 or EN60204 or UL508 regulations.
‰ The devices do not generally fulfill the requirements for "centralized DC power systems“ (UL 60950-1, Annex NAB; D2)
and therefore may not be connected to such devices!
Caution:
Energy hazards > 240 VA are present inside the chassis!
Activities such as system expansion with expansion cards, or maintanance have to be carried-out by
qualified personnel familiar with the associated dangers!
The installation instructions for the KISS 2U V2 Platform is the responsibility of the distributor.
When used as intended the KISS 2U V2 platform is to operate only closed and locked.
Only when the cover is properly installed, secured with the knurled screws on the rear and the cover
fastening screw on the front, and the access panel is locked with the key, it is ensured that the user
doesn’t have access to the internal parts of the KISS 2U V2 platform, loaded with hazardous energy.
4.1. Operation of Laser Source Devices
Fig. 1: Laser radiation warning label
The optional CD ROM and DVD drives contain light-emitting diodes (classified in accordance with IEC 60825-1:2007:
LASER CLASS 1) and therefore must not be opened.
If the enclosure of such a drive is opened, invisible laser radiation is emitted. Do not allow yourself to be exposed to this
radiation.
The laser system meets the code of Federal Regulations 21 CFR, 1040 for the USA and the Canadian Radiation Emitting
Devices Act, REDR C 1370.
