1.5.4 Flammability

The SBC330 circuit board is made by a UL‐recognized manufacturer and has a
flammability rating of UL94V‐1.

1.5.5 EMI/EMC regulatory compliance

CAUTION
This equipment generates, uses, and can radiate electromagnetic energy. It may cause or be
susceptible to EMI if not installed and used in a cabinet with adequate EMI protection.
The SBC330 is designed using good EMC practices and, when used in a suitably
EMC‐compliant chassis, should maintain the compliance of the total system.
The SBC330 also complies with EN60950 (product safety), which is essentially the
requirement for the Low Voltage Directive (73/23/EEC).
Air‐cooled build levels of the SBC330 are designed for use in systems meeting
VDE class B, EN and FCC regulations for EMC emissions and susceptibility.
Conduction‐cooled build levels of the SBC330 are designed for integration into
EMC hardened cabinets/boxes.
CAUTION
Only handle the board at the edges, heatsink, or front panel.
CAUTION
Do not remove the heatsink.
The heatsink is thermally bonded to the ICs and will generally not separate from
the board by removal of the screws alone.
There are no user‐alterable components underneath the heatsink, so users should
have no reason to remove it. With the SBC330, the SODIMM cover may be
removed and reattached by a user.
In rare instances a user may be specifically instructed to remove a heatsink cover
by GE staff. However, this does not mean that users should attempt reattachment
of the heatsink, as this requires precise torque on the securing screws. Over‐
tightening the screws may cause the heatsink to damage components beneath it.
Removal and re‐attachment of the heatsink should only be carried out by the
factory.
