Under abnormal conditions, such as a short on SCSI TERMPWR, + 5 V
current may be higher. At temperatures of at least 25
°
C, a current of
8 A is sustained no longer than 0.5 seconds before the self-resetting
TERMPWR short circuit protection device opens.

3.1.4 Electromagnetic Compliance
This board is tested to and meets class B regulatory requirements for the
United States, Canadian, European, Japanese, and Australian markets.
This board carries the appropriate markings (FCC, CE, VCCI, C-Tick)
indicating such compliance.
3.1.5 Safety Characteristics
The bare board meets or exceeds the requirements of UL flammability
rating 94 V0. The bare board is also marked with the supplier’s name or
trademark, type, and UL flammability rating. Since this board is installed
in a PCI bus slot, all voltages are below the SELV 42.4 V limit.
