Additional safety instructions for DC power supply circuits:
To guarantee safe operation of products with DC power supply voltages larger than 60 volts DC or a power
consumption larger than 120 VA, observe that:
Product is set up, installed and operated in a room or enclosure marked with “RESTRICTED ACCESS”, if there
are no safety messages such as safety signs and labels on the product.
Do not touch either directly or indirectly, cables or parts without insulation in electrical circuits with
dangerous voltage or power.
Reliable protective earth connection is provided
Suitable, easily accessible disconnecting device is used in the application (e.g. overcurrent protective device),
if the product cannot be disconnected
A disconnect device, if provided in or as part of the equipment, must 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’s type label – as stipulated by EN 62368-1 or VDE0100 or EN60204 or UL508
regulations.
The product 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!

Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive devices or micro-circuitry. Therefore,
proper packaging and grounding techniques are necessary precautions to prevent damage.
Always take the following precautions:
ESD Sensitive Device!
Follow the electrostatic discharge (ESD) precautions for components that are sensitive to
ESD. When handling ESD sensitive components use a clean, flat and ESD-safe workstation
and always be properly grounded. Failure to observe this warning notice may result in
damage to the product and internal components.
For more Information, see the Special Handling and Unpacking Instruction within this user guide and the Grounding
Methods below.
1.1.1.
Grounding Methods
The following measures help to avoid electrostatic damage to the product:
Cover workstations with approved antistatic material. Always wear a wrist strap connected to the workplace, as
well as properly grounded tools and equipment.
Use antistatic mats, heel straps, or air ionizers for more protection.
Always handle electrostatically sensitive components by their edge or by their casing.
Avoid contact with pins, leads, or circuitry.
Switch off power and input signals before inserting and removing connectors or connecting test equipment.
Keep the work area free of non-conductive materials such as ordinary plastic assembly aids and styrofoam.
Use field service tools such as cutters, screwdrivers, and vacuum cleaners that are conductive.
Always place drives and boards with the PCB-assembly-side down on the foam.
