equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio
communications. Operation of this equipment in a residential area (domestic environment) is likely to cause harmful
interference, in which case the user will be required to correct the interference (take adequate measures) at their own
expense.
CE
The product described in this manual complies with all applicable European Union (CE) directives if it has a CE marking.
For computer systems to remain CE compliant, only CE-compliant parts may be used. Maintaining CE compliance also
requires proper cable and cabling techniques.
Declaration of conformity iv

Safety precautions
Please read the following safety instructions carefully. It is advised that you keep this manual for future references.
• All cautions and warnings on the device should be noted.
• All cables and adapters supplied by SmartCow are certified and in accordance with the material safety laws and
regulations of the country of sale. Do not use any cables or adapters not supplied by SmartCow to prevent system
malfunction or fires.
• Make sure the power source matches the power rating of the device.
• Position the power cord so that people cannot step on it. Do not place anything over the power cord.
• Always completely disconnect the power before working on the system’s hardware.
• No connections should be made when the system is powered as a sudden rush of power may damage sensitive
electronic components.
• If the device is not to be used for a long time, disconnect it from the power supply to avoid damage by transient
over-voltage.
• Always disconnect this device from any AC supply before cleaning.
• While cleaning, use a damp cloth instead of liquid or spray detergents.
• Make sure the device is installed near a power outlet and is easily accessible.
• Keep this device away from humidity.
• Place the device on a solid surface during installation to prevent falls.
• Do not cover the openings on the device to ensure optimal heat dissipation.
• Watch out for high temperatures when the system is running.
• Do not touch the heat sink or heat spreader when the system is running.
• Never pour any liquid into the openings. This could cause fire or electric shock.
• As most electronic components are sensitive to static electrical charge, be sure to ground yourself to prevent static
charge when installing the internal components. Use a grounding wrist strap and contain all electronic components
in any static-shielded containers.
• If any of the following situations arises, please contact our service personnel:
• Damaged power cord or plug
• Liquid intrusion to the device
• Exposure to moisture
• Device is not working as expected or in a manner as described in this manual
• The device is dropped or damaged
• Any obvious signs of damage displayed on the device
• Do not leave this device in an uncontrolled environment with temperatures beyond the device’s permitted
environment with temperatures (see specification) to prevent damage.
• RTC battery warnings
• Use replacement batteries that comply with the recommended battery safeguards, especially for certain types of
lithium batteries.
• Do not dispose of batteries into a fire or oven, or crush them, as this can lead to an explosion.
• Do not leave batteries in extremely hot environments, as this can cause flammable liquids or gases to leak and
ignite.
• Do not subject batteries to extremely low air pressures, as this may cause flammable liquids or gases to leak,
resulting in an explosion.
Safety precautions v

RoHS compliance
SmartCow RoHS environmental policy
SmartCow is a global citizen for building digital infrastructure. We are committed to providing green products and
services, which are compliant with European Union RoHS (Restriction on Use of Hazardous Substance in Electronic
Equipment) directive 2011/65/EU and 2015/863, to be your trusted green partner and to protect our environment.
RoHS restricts the use of Lead (Pb) < 0.1% or 1,000ppm, Mercury (Hg) < 0.1% or 1,000ppm, Cadmium (Cd) < 0.01% or
100 ppm, Hexavalent Chromium (Cr6+) < 0.1% or 1,000ppm, Polybrominated biphenyls (PBB) < 0.1% or 1,000ppm, and
Polybrominated diphenyl Ethers (PBDE) < 0.1% or 1,000ppm.
In order to meet the RoHS compliant directives, SmartCow has established an engineering and manufacturing task force
to implement the introduction of green products. The task force will ensure that we follow the standard SmartCow
development procedure and that all the new RoHS components and new manufacturing processes maintain the highest
industry quality levels for which SmartCow is renowned.
The model selection criteria will be based on market demand. Vendors and suppliers will ensure that all designed
components will be RoHS compliant.
