1.1 Safety Notices
The following general safety precautions represent warnings of certain dangers of
which GE Intelligent Platforms is aware. Failure to comply with these or with
specific Warnings and/or Cautions elsewhere in this manual violates safety
standards of design, manufacture and intended use of the equipment. GEIP assumes
no liability for the user's failure to comply with these requirements.
Also follow all warning instructions contained in associated system equipment
manuals.
1.1.1 Flammability
The circuit board is made by a UL‐recognized manufacturer and has a flammability
rating of UL94V‐1.
1.1.2 Backplane Requirements
1.1.3 EMI/EMC Regulatory Compliance
The GBX24 is designed using good EMC practices and, when used in a suitably
EMC‐compliant chassis, should maintain the compliance of the total system. The
GBX24 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 GBX24 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 GBX24 are designed for integration into EMC
hardened cabinets/boxes.
Publication No. GBX24-0HH/2
WARNINGS
Use extreme caution when handling, testing and adjusting this equipment. This device may operate in
an environment containing potentially dangerous voltages.
Ensure that all power to the system is removed before installing any device.
To minimize shock hazard, connect the equipment chassis and rack/enclosure to an electrical ground.
If AC power is supplied to the rack/enclosure, the power jack and mating plug of the power cable must
meet IEC safety standards.
CAUTION
Only use the GBX24 in backplanes that supply power on both the J1 and J2 connectors. Use of
backplanes that supply power on the J1 connector only may cause excessive current to be drawn
through the power pins
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.
