Introduction
VL-EPMs-U1 Reference Manual 4
RoHS-Compliance
The VL-EPMs-U1 is RoHS-compliant.
ABOUT ROHS
In 2003, the European Union issued Directive 2002/95/EC regarding the Restriction of the use of
certain Hazardous Substances (RoHS) in electrical and electronic equipment.
The RoHS directive requires producers of electrical and electronic equipment to reduce to
acceptable levels the presence of six environmentally sensitive substances: lead, mercury,
cadmium, hexavalent chromium, and the presence of polybrominated biphenyls (PBB) and
polybrominated diphenyl ethers (PBDE) flame retardants, in certain electrical and electronic
products sold in the European Union (EU) beginning July 1, 2006.
VersaLogic Corp. is committed to supporting customers with high-quality products and services
meeting the European Union’s RoHS directive.
Warnings
ELECTROSTATIC DISCHARGE
Electrostatic discharge (ESD) can damage boards, disk drives, and other components. The circuit
board must only be handled at an ESD protective workstation. If an approved station is not
available, some measure of protection can be provided by wearing a grounded antistatic wrist
strap. Keep all plastic away from the board. Do not slide the board over any surface.
After removing the board from its protective wrapper, place the board on a grounded, static-free
surface, component side up. Use an antistatic foam pad if available.
The board should always be protected inside a closed metallic antistatic envelope during
shipment or storage.

Physical Description
Dimensions and Mounting
The VL-EPMs-U1 complies with SUMIT-ISM (Legacy Type 1) form factor, which provides for
specific mounting hole and stackable bus locations as shown in the diagram below.
Figure 2. VL-EPMs-U1 Dimensions and Mounting Holes
(Not to scale. All dimensions in inches.)
Caution The board must be supported at all four mounting points to prevent excessive
flexing when expansion modules are mated and detached. Flex damage caused by
excessive force on an improperly mounted circuit board is not covered under the
product warranty.
